Difference Between Array and Pointer

Arrays and pointers are fundamental concepts in programming, each with its unique characteristics and applications. Understanding the differences between these two is crucial for any developer. In this article, we will explore the Difference between arrays and pointers, shedding light on when to use one over the other.

What are Arrays? 

An array is a fundamental data structure used in computer programming. It serves as a systematic way to store and organize a collection of elements, all of which share the same data type. These elements are arranged in a contiguous block of memory, making it convenient for programmers to access and manipulate them.

Arrays have several distinctive characteristics:

Fixed Size: When you declare an array, you must specify its size, which remains constant throughout its lifetime. This fixed size distinguishes arrays from other data structures, like linked lists, which can dynamically adjust their size.

Sequential Storage: All elements within an array are stored one after the other in memory, creating a continuous block. This sequential storage simplifies data retrieval and manipulation.

Efficient Access: Accessing elements in an array is highly efficient because you can directly reference them using their index. This means you can quickly locate and work with specific elements within the array.

In programming languages like C and C++, array declaration follows a syntax like this:

int myArray[5]; // This line declares an integer array with a size of 5 elements.

Arrays find widespread application in various scenarios where you need to manage a fixed number of elements. For example, they are commonly used to store data like student grades in a class, daily temperatures, or the names of employees in a company directory. Arrays are a versatile tool that plays a fundamental role in many programming tasks.

What are Pointers?

Pointers are a fundamental concept in computer programming. They are essentially variables that store memory addresses of other variables, allowing for indirect access to the data stored in memory. Pointers are a powerful tool with a dynamic nature, and understanding how they work is crucial for efficient programming.

Here are some key characteristics of pointers:

Dynamic Memory Addresses: Pointers can hold the memory addresses of other variables, and these addresses can change during the program's execution. This dynamic nature makes pointers highly flexible.

Indirect Data Access: Pointers enable indirect access to data. When you use a pointer, you're not working directly with the data itself but rather with the memory location where the data is stored.

Flexible Usage: Pointers are versatile and are used for various purposes, including dynamic memory allocation, hardware interaction, and complex data structures like linked lists and trees.

In programming languages like C and C++, pointer declaration follows a syntax similar to this:

int x = 10;         // Declare an integer variable x and assign it a value.

int* ptr = &x;      // Declare a pointer variable ptr, which holds the memory address of x.

Common use cases for pointers include scenarios where you need to allocate and deallocate memory dynamically, interact with hardware or device registers, or work with data structures that can change in size during the program's execution.

Pointers are a fundamental tool in programming that adds a layer of indirection and flexibility to how you can manipulate and access data in memory, making them an essential concept for programmers to grasp.

A pointer variable can store the address of only one variable at a time.

An array can store a number of elements the same size as the size of the array variable.

5.

Pointer allocation is done during runtime.

Array allocation is done during compile runtime.

6.

The nature of pointers is dynamic. The size of a pointer in C can be resized according to user requirements which means the memory can be allocated or freed at any point in time.

The nature of arrays is static. During runtime, the size of an array in C cannot be resized according to user requirements.

Conclusion

In summary, arrays and pointers are essential tools in programming, each with its unique strengths. Arrays are ideal for fixed-size collections with efficient direct access, while pointers shine when dynamic memory allocation is needed or when working with complex data structures. The choice between them depends on your specific requirements and design considerations.

Synopsis: Chris likes how the donut glaze looks on your lips.

Warnings: Smut, p n v, cum eating, male receiving, and more.

With love and big tits, Rose

━━━━━━━━━━━━━━━━━━━━

The street lights reflected on the dashed white lines as I make a left turn down the street. Music had been stopped a while ago, Chris’s voice being the only source of noise.

“No, yesterday for a video idea we tried a bunch of different donuts, but they all sucked-well, except for maple, but still-I’d prefer glazed. I was craving donuts, not garbage.” Chris rants through the car speaker.

I let out a soft giggle, the same complaint that had already been explained to me at least three times.

“How far are you?” He questions.

Gazing around at my surroundings, his house is right around the corner. I had the map to his house memorized mindlessly at this point.

Afterall, we are best friends.

“Um-I’m at the ugly green house.” I mutter.

“I’LL BE AT THE DOOR IN FIVE SECONDS! SEE YA!” He yells as I hear the line go dead.

I park the car in his driveway, looking over at the plastic food container in my passenger seat. Before I have the chance to grab it, Chris is yanking open my door and pulling me into his arms.

“Fucking missed you. God, I think I’m going insane, you even smell like donuts.” He compliments, inhaling deeply with his nose against my neck.

Goosebumps travel up my spine from the sensation. I pull away from his embrace, seeing a slight pout appear on his lips.

“I made us donuts! They’re the homemade one I made for your birthday last-”

The sentence is long forgotten as I let out a shriek. Chris’s arms reattach to me, squeezing me while jumping up and down.

“I LOVE YOU I LOVE YOU I LOVE YOU!!!” He proclaims.

His voice echoes loudly so I place my pointer finger over his mouth. Chris shoves my hand off, holding it in his own.

“Don’t try to shush me! I’m excited! Now, let’s go in and eat!” He announces.

He leans into the open driver’s side door, grabbing the container on the adjacent seat and dragging me inside.

***

The cold kitchen counter feels freezing against the back of my thighs. I sit on the smooth granite, watching as Chris stands by the microwave.

“Why? I just want them now!” He whines with a child-like pout.

Laughing at his antics, I playfully punch him in the arm. “They taste better warm, remember? It’s only ten seconds!” I reason.

He begins to roll his eyes, but the beeping of the microwave snaps his attention back to the donuts. Pulling out the plate filled with an array of donuts, he places it on the counter next to me.

He moves in between my legs as he picks one up. He takes a colossal bite out of the warm desert and moans softly.

“Don’t be greedy!” I exclaim, placing a flat hand on his chest.

Chris moves the donut in front of my lips allowing me to take a bit. As my mouth waters from the sugary taste, I feel the warm glaze on my lips.

“Mmmmmmm, fuck these are so good.” I acknowledge, savoring the sweet taste on my tongue.

I bring my tongue out, licking my bottom lip clean as an attempt to wipe off the glaze. I shift my gaze up, seeing Chris’s intense stare.

He was staring with a certain look.

A look best friends don’t give each other.

“Chris?” I ask, calling him back to reality.

He shakes his head slightly, “Sorry, zoned out there for a minute,” He responds.

I move my hand that lays flat on his chest up onto his shoulder. He didn’t have a shirt on, which wasn’t unusual, and neither was me touching him. We constantly were hugging or leaning into each other.

Physical touch was our main way of showing how much we cared about one another.

One time, we had decided to get severely high together. One thing led to another and…we really showed physical affection. Especially him as he fucked me into pure bliss. The next morning, we agreed never to talk about it again.

But that didn’t stop me from thinking about how good he fucked his cock up into me all the damn time…

Especially right now.

The cold counter beneath me did almost nothing to soothe the heat between my legs. A burning of desire building up as I felt myself be overcome with a need for him.

“Here, open.”

I open my mouth, letting him place the donut inside.

As I take a bite, he pulls it away, brushing it all over the side of my face. His eyes look hypnotized at the sight.

“Chris!” I exclaim.

I pull my hand off of his bare shoulder to cover my mouth as I chew.

I barely finish swallowing the donut as he shoves it in my mouth once more, catching me off guard. More glaze is decorated on the side of my face, practically dripping from my chin.

That wasn’t the only thing dripping either.

I meet his gaze, the heat becoming hotter between my legs. I let my thoughts wander to the familiar memory of the hazy night we spent together. The night we were tangled up in the sheets with no regrets until the morning.

“Chris, are you even gonna eat the donuts I made you? I thought you were craving them!” I reclaim, holding his wrist back from shoving the warm dough back into my mouth.

Using my other hand, I grab the napkin next to us and wipe my face off.

“I’m not craving donuts anymore.”

The way the sentence falls out of his mouth makes my thigh squeeze together subconsciously, closing in around his torso.

“Chris…” I warn.

Chris places the donut back down on the plate, pulling me towards him. My legs wrap completely around him as he rests his hands where my hips and thighs meet, caressing with a firm grip.

“Chris…we can’t. We’re best friends.” I remind.

His face doesn’t falter in the slightest. His gaze only focused on my lips.

“How often do you think about it?” He asks.

He pulls his face down to the crook of my neck, leaving slow, soft, teasing kisses. My mind goes blank, but I don’t push him away. I rest my weight back on one hand behind me as my other one wraps in his hair.

“Think about what?” I ask, a newly found neediness clouding my emotions as I anticipate his response.

“Us. That night.” He mutters, his lips continuing against my neck.

I snapped back into my senses, “Chris. We agreed not to talk about it.” I state.

“You don’t wanna talk about how good I fucked you? How perfect you looked taking my cock, hm?”

I feel myself clenching around nothing at his words. His lips become hungrier, starved as his kisses turn to sucking and sucking turns to biting. I grind myself against him, attempting to get some sort of friction subconsciously. He pulls back up to my face, looking me directly in the eye.

“You gonna answer me or do I need to get it out of you in a different way?” He cocks an eyebrow up, tilting his head slightly to the side.

I don’t say anything. Instead, I fist my hand in the collar of his shirt and bring him down to me. He doesn’t hesitate, kissing me back with an aggressive passion.

Becoming dizzy from the lack of air, I pull back. He lets his lips kiss the side of my mouth, trailing a path down to the base of my throat.

One of his hands snakes up under my oversized shirt, a light pressure from a single fingertip tracing my skin as his lips are all over my neck. He places his palm flat, caressing my torso right below my breast.

“Do you want this?” He asks, pulling away to look up at me.

I nod my head, “Touch me, Chris.” I reply.

He grins at me, his hand covering my breast before tweaking the nipple, making me moan as I wrap my hand back in his hair. He brings his lips back down, ravishing each inch of my neck with a mix of soft kisses, harsh sucking, and light nibbles on the skin.

I couldn’t help but rock my hips against his hard erections, making him groan against my neck.

He pulls away once more, bringing his hand to take off my shirt in one swift movement. His lips come down to my chest, using the same pattern that he used on my neck.

It felt more than just good.

From the way his mouth was moving against me, his other hand rubbing the top of my thigh, getting closer and closer to where I wanted him most, to the friction I got from moving my hips to grind on his hardness.

It all felt fucking amazing.

Shamelessly, I let every sound slip out of my mouth, encouraging him as he continued.

“Why don’t you get on your knees for me, sweetheart…” he trails off, bring his hand up to my face and swiping his thumb against my bottom lip, “Wanna fuck your mouth and cum on your pretty little face.” He finishes, a daring look peering into my eyes as I look at him.

I nod, he helps me off the counter, pulling my sweats off as well. I let my knees land on the hard, wooden floor and place my hands on the tops of his thighs to support my weight.

I put my hand on his clothed dick, trying to pull his waistband down, but he stops me. “Uh-uh-uh, not so fast…gotta put your hair up first, hm? Good thing I always have a hair tie for you.” He remarks, pulling the black elastic off his wrist.

He had always carried around a hair tie for me. After I had complained about losing them, or not having one when I needed it, he bought some and always made sure to have one for me.

It was endearing and sweet, making me feel a warmth of comfort.

This didn’t though.

This made me burning hot, desire flooding as I watched him bring his hands behind my head. He starts gathering my hair softly, pulling it into one spot.

I gasp as I feel the abrupt movement of him yanking me back by my hair, pure want written all over his face as he stares down at me.

“Gonna be a good girl and let me fuck your mouth?” He asks, looking down at me for a response.

“Please.”

As the word leaves my mouth, he places the hair tie in my hair and finishes putting my hair up.

“Good girl, now open up for me.” He directs.

He lets one hand stay on the back of my head, holding me by my hair. The other pulls out his hard dick, placing the tip against my lips. I gather spit in my mouth, licking up and down his shaft as best I can to lubricate his hard length.

I bring my hand up, jerking him slightly. He pulls my hair back, grabbing my wrist with one of his hands.

“No hands. I just want to fuck your mouth. Can you do that for me?”

I nod, sticking out my tongue.

“Mmmmm fuck.” He hisses out, sliding his wet cock in my mouth as I cover my teeth with my lips.

Only around half his length is slowly thrusting in my mouth. I get antsy, moving my mouth forward to take more of him. He pulls harshly at my hair, keeping me in place.

“Who's greedy now, hm?” He teases, thrusting his entire length in my mouth.

Tears immediately well-up as his pace ensues faster and faster. I can feel him sliding down the back of my throat. I gag each time he reaches the back, his head thrown back at the sensation.

“Just like that-fuck!” He exclaims, picking up his pace.

I can tell he’s close by the way his hips become messier in their movements and the way his hand grips my hair tighter.

He looks down at me as I stare up at him through my eyelashes, watching as he furrows his eyebrows and his mouth hangs slightly open.

“Fuck fuck fuck!”

He grips my hair, gripping hard as he holds me back.

“Open up, pretty girl.”

I succumb to his request, opening my mouth and sticking out my tongue. He jerks himself off, white spurts of cum landing mostly on my tongue as some falls onto my face.

He drops his throbbing cock, letting his hand in my hair pull me at an angle to lean me back and face up at him. He takes his other hand, wiping my face before shoving it into my mouth.

“Mmmm…looks even better than I imagined. I wonder what my cum would look like dripping out onto your thighs…”

I swallow the salty liquid, “Why don’t you find out?” I urge.

A sadistic smile creeps on his face as he yanks me to my feet by my hair, “If you say so. Bend over for me, princess.” He commands, pushing me against the counter.

I bend over, the cold counter making my nipples harden from the sudden change. But, it doesn’t last long as everything starts to get hotter and hotter.

His hand rubs my thighs from behind, spreading them as he rubs over my heat, making me moan.

“So wet, baby. This all for me?” He asks.

“Yes, fuck.” I moan out, his hand wrapping in my hair again as his other directs his cock towards my entrance.

“Tell me, princess. How often do you think about that night?” He asks.

I grind my hips back, attempting to get some sort of friction. He immediately drops his dick, his hand slapping against my ass with a loud snap.

“Tell me or I’m not giving you anything.” He threatens, leaning down and whispering the dirty words into my ear.

“Fuck-all the time! Every time I touch myself, every time I think of you. Please!” I beg, wiggling my hips in desperation.

“Tell me what you think about, baby.” He requests.

My mind is hazy, but all I can think about is how much I need him.

“I-I…I think about how you were-fuck!” I scream out, putting my hands behind to push him away as he forces his entire length into me, filling me with a gut-wrenching stretch.

“Keep talking, baby. Doing so good, just keep talking.”

I take in a deep breath, feeling him grind himself into me and letting me adjust to the feeling.

“T-think about-um-how you were pounding into me-mmmm..” I moan, the feeling of him pulling out and pushing in slowly bringing me an undeniable pleasure.

“You like it when I pound you, princess?” He questions.

“Yes!” I let out, my hands feeling his bottom abdomen as his stomach flexes. “Fuck, too much!” I scream out.

As my hands push on his stomach, he grabs both of my wrists with one hand and pins them to my back.

“Hey…it’s okay, you’re taking me so good, princess.” He comforts, thrusting at a slow pace deeply.

I moan, clenching around him as he starts picking up the pace.

“You want me to pound you, hm? Remind you how good it feels?” He asks, a loud clapping noise sounding as our skin slaps together with each thrust.

“Please!”

The simple word seems to adhere. Chris starts pounding relentlessly up into me, fucking his cock up in my gut.

“Fuck-you feel so good. So close, yeah?” I moan out as a response, letting myself clench down around his cock as my mouth falls open with deep moans.

“Good girl. That’s right, princess. Cum all over my dick.” He praises, slowing down his pace as I ride out my orgasm.

However, he doesn’t stop or pull out. Instead, he starts fucking up into me again.

“You’ll give me one more, right baby? You can do it.” He says.

I nod my head, letting the pleasure build up once more as he pushes me further down into the counter. The pressure on my lower stomach makes his dick pounding in and out of me even better.

My mouth opens wide, a strangled moan coming out as I cum around him once again.

“Gonna be greedy with my cum in your pussy too?” He says, leaning down as his breath fans against my ear.

I nod, writhing beneath him as his thrusts become more erratic.

I feel his cum fill me, leaking out as he pulls out.

I try to stand up, but his hand holding my wrists pushes me back down. I feel his hand let loose of my hair, pulling my thighs apart.

“Looking so pretty with my cum dripping all over you.” He compliments, rubbing the skin of my thigh roughly.

He lets go of my wrists, pulling me against his chest.

“You okay?” He asks, laughing at my fucked-out expression.

I nod my head, letting my weight fall onto him. He pulls my clothes back on me, setting me back on the counter as stands in between my legs.

My eyes are closed as I try to catch my breath.

“These donuts are so fucking good.” I hear his muffled voice say, his mouth full as I look up at him to see him finishing the donut from earlier.

I laugh at him, “Yeah, well…they’re better when they’re warm.” I remark, echoing my same statement from earlier.

He rolls his eyes, shoving the donut into my mouth. I give him a blank look, remembering his previously similar antics.

“It’s just a glazed donut this time, I swear!” He exclaims, holding his hands up in defense.

“Okay…” I trail off, accepting the bite.

He moves the donut back to his mouth, chomping on another large bite.

“I fucking love glazed donuts.”

Say, for the sake of argument, you want to make a bad programming language. Why would you do this?

Well, for instance, you might get your hands on a book of scripts to generate ephemera for celestial events, only to find out it was written for Microsoft QuickBasic for Macintosh System 7. You quickly discover that this particular flavor of BASIC has no modern interpreter, and the best you can do is an emulator for System 7 where you have to mount 8 virtual floppy disks into your virtual system.

You could simply port all the scripts to another BASIC, but at that point you might as well just port them to another langauge entirely, a modern language.

Except QuickBasic had some funky data types. And the scripts assume a 16-bit integer, taking advantage of the foibles of bitfutzery before converting numbers into decimal format. BASIC is very particular -- as many old languages are -- about whitespace.

In addition to all this, BASIC programs are not structured as modern programs. It's structured to be written in ed, one line at a time, typing in a numbered index followed by the command. There are no scopes. There are no lifetimes. It's just a loose collection of lines that are hopefully in a logical order.

So sure, I could port all these programs. But I'm sure to make mistakes.

Wouldn't it just be easier, some basal part of my brain says, to write your own language that some some modern ameneties, that you compile for your own laptop, that kind of acts like BASIC? A language where you just have to translate particular grammar, and not the whole structure of the program?

Of course it's not easier. But I'm already too far in to quit now.

Memory

Who doesn't love manual memory layout?

In QuickBasic, memory is "kind of" manual. The DEFINT and DEFDBL keywords let you magically instantiate types based on their first letter. I don't know how you deallocate things, because all the scripts in this book finish quickly and don't hang around to leak a lot.

In QuickBasic, this looks like

I guess that the second statement just overrides the first.

There is no stack in a BASIC program, so there will be no stack in my language. Instead you just give names to locations.

creates a symbol named age and makes it refer to 0x1F. The pointer operator should be obvious, and the walrus means we're defining a symbol (to be replaced like a macro), not doing a value assignment during the execution of the program. Now we can assign a value.

Atoms infer types. age knows it's an int.

You cannot assign a new type to an atom.

However, you can cast between types by creating two atoms at the same address, typed differently.

The language does not convert these, it simply interprets the bits as the type demands.

Larger types

Not all types are a single word. Therefore, you can use the range operator .. to refer to a range of addresses.

Note that strings are stored with an extra byte for its length, instead of null-terminating it. Assignment of a string that is too long will result in a compilation error.

Next and Auto

There are also two keywords to make the layout of memory easier. The first is :next which will place the span in the next available contiguous location that is large enough to hold the size required. The second is :auto. For all :auto instances, the compiler will collect all these and attempt to place them in an intelligent free location. :auto prefers to align large structs with 64-word blocks, and fills in smaller blocks near other variables that are used in the same code blocks.

String Allocation

Strings come with a macro to help automatically build out the space required:

This is equivalent to:

That is, a string with capacity 5, a current size of 0, and zeroes (null char) in all spots. This helps avoid memory reuse attacks. ZBASIC is not a secure language, but this is still good practice.

There is also another macro that is similar to a "string literal".

Verbose and annoying! Just like BASIC.

Array Allocation

Likewise, arrays have a similar macro:

Which expands in a similar way as strings, with a capacity word and size word. The difference here is that the type given may change the actual size of the allocation. Giving a type that is larger than a single word will result in a larger array. For instance, f64 takes up two words some systems, so array::empty!(5, f64) will allocate 10 words in that case (5 * 2). Larger structs will likewise take up even more space. Again, all this memory will be zeroed out.

Allocation order

As an overview, this is the order that memory is assigned during compilation:

Manual Locations -> Next -> Auto

Manual locations are disqualified from eligibility for the Next and Auto phases, so a manual location will never accidentally reference any data allocated through :next or :auto.

Here is an example:

This produces the initial layout:

Which, after the code is run, results in the memory values:

Note that types are not preserved at runtime. They are displayed in the table as they are for convenience. When you use commands like "print" that operate differently on different types, they will be replaced with one of several instructions that interpret that memory as the type it was at compile-time.

Truly awful, isn't it?

May I present some pages from Hanako's Teacher's notes about the Solar Magi (along with my commentary)!

The Solar Magi are the "strikers" of the Magi species, usually possessing personal innate magic that's flashy and/or inherently destructive. They're also the only Magi subspecies with the ability to fly in both their full and hybrid forms, and are considered the fastest of all Magi subspecies on average.

-Despite most of their features resembling various birds, their pupils most closely mimic a gecko's.

-The second eyelid serves the same purpose as a bird's and, yes, they are transparent! It's believed the black points to their eyes help with 'hunting'.

-The average human usually only comes up to their shoulder, but they're still not the tallest of all Magi. That honor goes to the Abyssal Magi.

-Of the four Magi subspecies, they're the only one to keep a mostly human face between their forms.

-Solar Magi feathers come in a wide array of colors and shapes. Sometimes, they mirror actual bird species, such as owls, ravens, sparrows, and more. Other times, their coloration and decorative feathers are completely unique and can't be traced back to any particular animal species.

-One of the few traits shared across all Solar Magi is that they all have feathers under their eyes that reach back to the feathers lining their ears. However, how these feathers look varies.

-The above samples are NOT the only examples of Solar Magi feathers, just a select few examples.

-Solar Magi and Abyssal Magi are considered the more colorful Magi subspecies due to what animals they draw traits from.

-Like the rest of their feathers, their wings often mimic actual bird wings, but not always. Hanako's wings are intended to closely mimic a peregrine falcon's, although the rest of her design doesn't match any other known bird.

-All Solar Magi have three-fingered hands - the thumb, the pointer finger, and what's considered the middle finger on a human hand. The wrist doesn't have the full rotation a human wrist does, but it still has quite a bit of motion.

-Solar Magi know multiple spells relating to making flying safe for themselves, which include spells to alter how they take in air mid-flight, warm up their human-esque hybrid forms, and more.

-A Solar Magi's wings look very different between their hybrid form and full Magi form. Their Magi form look most similar to what is shown above. In their hybrid form, their wings are made of whatever element their personal innate magic is. In Hanako's case, her hybrid wings take the form of solidified light.

For an example of their hybrid form, take a look at the drawing here (note that some of the feather patterns are already considered outdated):

Why, What, and How; tuples in rust

When I first learned rust tuples were a tad funky, they were like arrays, but not index-able at runtime, I had never really touched something like that before (to my understanding), so I figure I should share my way to get my head around them.

Why

tuples serve simple role, compound multiple types into one, which is great for returning multiple values, if I want to return a string, and some sort of flag to say what that string could be representing, I can just return (String, T), then the caller can use T to determine what to do instead of mucking around with complicated string parsing.

perhaps I need two or more values of possibly different types to represent what I'm representing, for example a simple Linked list node may want to be an optional pointer to the next node, and it's value; Like (T, Option<Box<(T, Option<Box... wait a minute this is recursive, It needs a name to be written out like this so you should use a struct not a tuple! but what's a struct?

What

something that blew my mind is the ability to know what a struct is, it's an named tuple, if you give a tuple a name, and maybe some trait impls or methods, you've made a struct, simple as.

this is why the syntax to get a field and to get a tuple element is so similar, tuples use numbers instead of names, but their the same concept.

but that doesn't actually explain what a struct or a tuple is, it's pointing to the other and saying their the same.

How

a tuple is a chunk of contiguous memory, with a known (to the compiler) layout, it's like if an array could have multiple types, it holds all it's elements together in a sequence and you can cut out all but the value you want since you know where it is already. the reason you can't index them at runtime is that array indexing is done by moving X bytes over in memory in the array to reach the next element, which only works when you know what size something is going to be and what type it is.

A fun edge case, unit, or ()

unit is a seemingly useless type, why have a compound of nothing? it's purpose is definitely a valid one, having a single value type is a great way to round off the Rust type system, it takes no space, it's the representation of nothing, but why an empty tuple instead of some special primitive? I'd bet it's cause consistency, () has all the properties you would expect an empty tuple to have, an already existent syntax meaning no new keywords or names need be learned to use it, and is straightforward representation of nothing.

Tuple Tips!

if you're tuple is made of less than 13 elements that all implement Default, the tuple does as well, it's default value is all the default values of its elements.

if your using two equal length arrays and want to pair them together, consider instead make an array of two element tuples; think [(T1, T2)] instead of ([T1], [T2]), great for iterating over pairs of statically known values.

if your struct is just some behavior over a simple enough set of values (like an Rgb type just being (u8, u8, u8)), consider implementing Into and From for those tuples so you can easily convert between them

Ready to dive deeper into C programming and other coding skills? Check out our Programming Course to get started!

1. What is C language?

Answer:

Think of C as a general-purpose procedural programming language designed by Dennis Ritchie in the 1970s; It meets our needs for system programming because of its fast speed, simplicity, and ability to access low-level memory.

2. What are the basic data types in C?

Answer:

They are basic data types, which include:

int (Integer)

float (Floating-point)

char (Character)

double (Double precision floating-point)

3. What is a pointer in C?

Answer:

In C, a pointer is a variable that keeps the memory address of another variable. It is used for creating dynamic memory management and working with arrays efficiently.

4. What is the difference between ++i and i++?

Answer:

++i means increment NOW, i. e., increment before using in any expression; i++ means use the current value of the variable in an expression and then increment it.

5. What is the use of sizeof operator?

Answer:

It returns the size of memory (in bytes) that a data type occupies. For instance, sizeof(int) may return 4.

6. What is the difference between call by value and call by reference?

Answer:

Call by value: passes the copy of the variable, so changes made inside the function do not affect the original.

Call by reference: passes the actual address so that changes modify the real variable.

7. What are storage classes in C?

Answer:

Storage classes tell us about the scope, lifetime, and visibility of variables:

auto

extern

static

register

8. What is recursion in C?

Answer:

Recursion is a condition wherein the function calls itself. It’s generally applied for calculating factorials or Fibonacci values.

9. What is a NULL pointer?

Answer:

A NULL pointer is a pointer that points to no location in memory. It is used for error handling and safe pointer initialization.

10. How would you differentiate between structure and union?

Structures allocate separate memory spaces to each member.

Unions allocate the same space in memory to all members, which saves space but allows it to hold only one value at a time.

Conclusion

These top 10 questions are about some of the basic concepts of C that are normally asked in interviews. So having command over these will surely be very helpful in boosting your confidence and making you a stronger candidate.

Digital vs. Analog Weighing Scale: Which One is Better?

For business owners, the question of which type of weighing to choose may often arise. Whether to choose an analog scale or a digital one. There are many pros associated with both these scales and each has its own set of benefits. In this blog, we will understand the difference between these scales and compare the properties to finally know which is better to use.

Understand How They Work

Before we get into comparison, let’s understand how both these scal es work:

Digital Weighing Scale: A Digital Weighing Scale uses chemical cells which contain strain gauges. When the load is placed on the pan, the load cells bend slightly, which changes the resistance of strain gauges. This change is converted into an electrical signal and processed into a digital weight signal, which is then displayed on the screen.

Analog Weighing Scale: The analog weighing scale is divided into two types- spring and beam balance. In spring type, when weight is placed, the spring compresses and this deformation is translated into weight by pointer or dial. In beam balance, the dial is at the center when weight on both beams is equal.

Differences

Accuracy & Precision: The strain gauges in the digital scales give accurate and precise readings. It is unaffected by vibrations and environmental disturbances. On the other hand, the Analytical Balance relies on needles, dials and pointers which are not very accurate and may give results that have higher deviations.

Heavy Duty Applications: Analog scale may be accessible for simple weighing operations at grocery stores. But for heavy duty applications where the load may go up to thirty thousand kilograms, it is not applicable. While digital scale of crane type can handle heavy duty load.

Ease of Portability: In general duty applications the digital scales are compact and lightweight. Hence they have a good portability factor. On the contrary, the two pans of analog scales make it heavier and not easy to portability.

Usage: The usage of digital weighing scales is wider than that of analog ones. It can be manufactured for small to heavy duty applications as well. When integrated with software, it offers multiple functions like counting, storing memory, etc.

Tare Function: The digital scales have a tare function that allows the display screen to give zero reading when only the container is kept on it, so that the user may not need to subtract the weight of the container from the final reading to get the net weight of the item. The analog scale has no tare function.

Conclusion

Our comparative overview shows the digital weighing scale is better than analog Weighing Scales. The accuracy, ease of use, lightweight build, and wide array of features make it useful in diverse applications. It can be integrated with software to work as a counting scale too. So, whether required in retail stores for weighing grocery and household items, or raw materials and components at the industrial level, digital weighing scales are the better option than analog scales.

We at Samurai Technoweigh provide a large variety of Digital Weight Machine. From Floor series for medium duty, and crane series for heavy-duty to tabletop scales for retail stores, we have digital weighing scales for all kinds of purposes.

C Programming Interview Questions: Test Your Knowledge Before the Interview

Preparing for a job interview can be stressful, especially when it comes to technical roles that demand strong programming skills. If you're applying for a role that involves C programming, it's crucial to sharpen your understanding of the language. That’s where revisiting C Programming Interview Questions can help you gain an edge. Whether you’re just starting out or brushing up your knowledge, this guide will walk you through the kind of questions that often come up in interviews and help you reflect on your grasp of C.

Why Interviewers Love C

C is one of the oldest and most powerful programming languages. Its simplicity, performance, and low-level memory manipulation make it the foundation of many operating systems, embedded devices, and real-time applications. Interviewers love C because it reveals a candidate’s depth of understanding about how software interacts with hardware, how memory is managed, and how algorithms are constructed at a low level. A strong command over C shows that you’ve built your programming knowledge from the ground up.

The Importance of C Tutorial Practice

Before jumping into specific C Programming Interview Questions, it’s essential to walk through a structured C Tutorial. Reviewing basics like data types, control structures, functions, and arrays lays the groundwork. As you progress, you should also focus on pointers, memory allocation, and structures—these are often seen as “make or break” topics in technical interviews. Even if you’ve worked with C in the past, refreshing these concepts through tutorials helps bring everything back into focus.

Core Concepts Interviewers Test

Let’s explore some of the key areas interviewers typically cover when asking C programming questions:

Memory Management: Expect to be tested on how C handles memory—both stack and heap allocation. You should understand concepts like dynamic memory allocation, memory leaks, and buffer overflows.

Pointers and Arrays: One of the most common and trickiest parts of C. Interviewers often want to know if you truly understand how pointers work, how they interact with arrays, and how pointer arithmetic can be used (or misused).

Data Structures: Even though C doesn’t have built-in data structures like lists or maps, you’re expected to know how to implement them using arrays, structs, and pointers. Interviewers may ask conceptual questions or have you describe how to organize data efficiently.

Functions and Scope: Knowing how functions work in C, including parameter passing, recursion, and variable scope, is essential. You might be asked about the difference between global and local variables, or how static variables behave.

Compilation and Execution: Understanding how C code is compiled and linked can be a big plus. Interviewers may ask about header files, macros, and the difference between declarations and definitions.

Edge Cases and Problem Solving: You might get questions that aren’t strictly about C syntax, but about how to solve a problem efficiently in C. These could test your logical thinking, debugging ability, or creativity in using C’s features.

Behavioral vs. Technical Balance

While it's easy to focus entirely on technical preparation, remember that interviews are also about communication. When answering C Programming Interview Questions, try to explain your thought process clearly. Even if you don’t know the answer right away, showing how you break down a problem can leave a positive impression. Being able to explain technical concepts in simple terms shows that you truly understand them.

Preparing Strategically

Start by identifying your weak areas. Did you struggle with pointers in your last project? Are you unsure about how memory leaks occur? Use your C Tutorial sessions to focus on these gaps. Practice answering questions out loud, even if you're by yourself. Simulating interview conditions helps reduce anxiety and improves your fluency in technical discussion.

Mock interviews with peers or mentors can also be helpful. Getting feedback not only helps you improve but also builds your confidence. Remember, interviews aren’t just about technical knowledge—they’re about demonstrating your ability to think and communicate effectively.

Final Thoughts

There’s no shortcut to mastering C, but by working through C Programming Interview Questions and revisiting your C Tutorial foundations, you can walk into your interview with confidence. Preparation is more than just reviewing facts—it’s about understanding concepts deeply and being able to explain them clearly. Use every question as a chance to show not only what you know, but how you think.

So before your next interview, challenge yourself with a mix of theoretical and practical C questions. Make your understanding bulletproof, and walk into that interview room ready to impress.

Do you want to know the difference between memcpy and memmove?  We’ve got you covered with this guide.  Memcpy and memmove are built-in C language functions that work similarly—copying memory blocks from one memory address to another within C.  However, the two are not the same, and they have varying, specific functions.  It’s crucial to know the difference between the two to understand which function to leverage in specific use cases.   After all, you need to determine the best tool and method to use, such as when deciding when to pick Crystal programming language to develop software.  This guide covers the main differences between memcpy and memmove to help you understand how each works and when to use them best.  Let’s go.  Memcpy and memmove: An overview Memcpy is a C function used for copying a specific number of bytes or data (n characters) from a single location or array (source object) to another (destination object).  The function helps you copy or move data across memory locations.  Memcpy is crucial since memory, which are electronic components, can’t store infinite data, making it necessary to move your data to other locations to free up some space.  Consider the following when using memcpy: Ensure you copy data to and from objects that don’t overlap, or the behavior will show as undefined.  Include a header file before using the function.  Specify the number of bytes before using the memcpy function to copy the memory areas.  Copy memory areas or regions that are the same data type.  The best way to understand the function is to look at memcpy examples and their use cases.  Memcpy syntax: void *memcpy(void * restrict dst ,const void * src ,size_t n); Where:  src is the pointer to the source object  dst refers to the pointer to the destination object n is the number of bytes you wish to copy. The memmove function also copies data from one location to another.  However, memmove copies the data from the source object first and moves it to the temporary array.  Then, the function copies the data from the temporary array to the destination object. It allows you to copy between objects that can overlap.  The function prevents an undefined behavior when your source and destination objects overlap.  Memmove Syntax: void *memmove(void * restrict dst, const void *src, size_t n); Memmove’s basic parameters are the same as memcpy.  Implementing memcpy and memmove in C Generally, it’s best not to create your own memcpy since your standard or compiler library likely has a tailored and efficient memcpy implementation.  However, some situations call for creating your own memcpy function to work around certain limitations.  You can create a memcpy function with a simple memory-transfer algorithm that reads one byte individually, writing the byte before reading the next.  While this algorithm is pretty easy to deploy, it doesn’t always offer optimal performance, especially with memory buses that are wider than 8 bits.  As you can see in the code below, lines seven and eight handle the scenario so that the source and destination memory is not NULL.  Lines 10 to 15 contain a while loop that copies the data from the source to the destination one at a time and increments the source and destination pointer by one.   Similar to memcpy, your standard or compiler library will likely have an efficient memmove function implementation.  That being said, unless there are special use cases, avoid creating your own memmove function.  Implementing memmove is similar to memcpy.  The difference is that it can handle an overlapping scenario through a temporary array.  The code below copies all the n characters to a temporary array first, then copies the temporary array data to the destination.  Key differences between memcpy and memmove Below are the main differences between the memcpy and memmove functions:

Memcpy returns undefined behavior if the memory location that the source and destination pointers point to overlap.  On the other hand, memmove has a defined behavior that can handle overlapping scenarios. If you’re unsure if there is overlapping, your safest bet is to use memmove. It’s best to use memcpy when forwarding or duplicating copies and memmove when there is overlapping.  Memmove is generally slower than memcpy because the memmove function uses an extra temporary array to copy data before copying the stored data to the destination.  Important considerations when using memcpy and memmove While the memcpy and memmove functions work well, it’s best to know their limitations before using them, including the following: The memcpy and memmove functions can show undefined behaviors if you access the source and destination buffer beyond their lengths.  Memcpy and memmove don’t check the destination and source buffer’s validity.  The memcpy and memmove functions don’t check the terminal null character.   Memcpy has limitations. For instance, the memcpy function can fail if the source parameter that is pointed to is in a shared block memory (between processes). Memmove allows memory regions to overlap but can require additional overhead than memcpy, including extra memory, resources, etc.  Quick summary: memcpy vs memmove Check out the quick memcpy and memmove comparison below.  memcpymemmovePurposeCopies data directly from the source to the destination.Copies data to the temporary buffer or array before copying it to the destination.OverlapShows a wrong output (undefined behavior) when the source and destination overlap. Can handle overlaps by copying to a temporary array first. Performance Faster than memmoveTwo times slower than memmove.Best to useIn general use cases When the source and destination overlap. Memcpy vs memmove: Which is better? Using memcpy or memmove depends on your data and whether the source and destination overlap.  While the memcpy and memmove functions give the same results, it’s best to know how each works to ensure you use them correctly and effectively.  Both C programming language functions make it easier to move your data but ensure you understand their limitations before you start copying and moving.  Doing so helps you minimize potential data loss and avoid using an inefficient method to move large amounts of data.

Understanding String Copying in C++: A Complete Guide

Copying strings in C++ copy strings is a common task that comes up in various programming scenarios, from simple assignments to complex string manipulations. Understanding how to copy strings efficiently and safely is crucial for writing robust and maintainable C++ code. In this post, we’ll explore the different ways to copy strings in C++, along with examples and explanations to guide both beginners and experienced programmers.

Using the Assignment Operator

In C++, you can copy strings easily using the assignment operator (=) when working with std::string. This method creates a deep copy of the string data.

#include

include

int main() { std::string original = "Hello, World!"; std::string copy = original; // Copy using assignment operator

std::cout << "Original: " << original << std::endl; std::cout << "Copy: " << copy << std::endl;

return 0; }

Output:

Original: Hello, World! Copy: Hello, World!

This method is straightforward and widely used when working with std::string.

Using the std::strcpy Function

If you’re dealing with C-style strings (null-terminated character arrays), you can use the std::strcpy function from the header. This function performs a copy of the source string into the destination array.

#include

include

int main() { const char* source = "Hello, World!"; char destination[50];

std::strcpy(destination, source); // Copy using std::strcpy

std::cout << "Source: " << source << std::endl; std::cout << "Destination: " << destination << std::endl;

return 0; }

Output

Source: Hello, World! Destination: Hello, World!

Note: Ensure that the destination array has enough space to hold the source string, including the null terminator, to avoid buffer overflows.

Using std::copy for Custom String Handling

For custom string types or scenarios where you need more control, the std::copy function from the header can be used.

#include

include

int main() { const char source[] = "Hello, World!"; char destination[50];

std::copy(source, source + sizeof(source), destination); // Copy using std::copy

std::cout << "Source: " << source << std::endl; std::cout << "Destination: " << destination << std::endl;

return 0; }

Output:

C-String: Hello, World! String Copy: Hello, World!

5. Deep Copy vs. Shallow Copy

It’s important to understand the distinction between deep and shallow copies. While std::string handles deep copies internally, copying pointers or dynamically allocated strings requires explicit handling to avoid dangling pointers or memory leaks.

Conclusion

Copying strings in C++ can range from simple to complex depending on the type of strings and the requirements. Using std::string is generally the most efficient and safest method, while C-style strings require careful memory management. By mastering these techniques, you’ll be able to handle any string copying scenario with confidence.
