My program crashed for an hour or so and I tried to fix it

I finally fixed it

Twas a fucking compiler command gone bad

My code was good

Mastering Linked Lists: Beginner's Guide

Hey Tumblr friends 👋

After learning about Arrays, it's time to level up! Today we’re diving into Linked Lists — another fundamental building block of coding! 🧱✨

So... What is a Linked List? 🤔

Imagine a treasure hunt 🗺️:

You find a clue ➡️ it points you to the next clue ➡️ and so on.

That's how a Linked List works!

🔗 Each element (Node) holds data and a pointer to the next Node.

It looks something like this: [data | next] -> [data | next] -> [data | next] -> NULL

Why Use a Linked List? 🌈

✅ Dynamic size (no need to pre-define size like arrays!) ✅ Easy insertions and deletions ✨ ✅ Great for building stacks, queues, and graphs later!

❌ Slower to access elements (you can't jump straight to an item like arrays).

Basic Structure of a Linked List Node 🛠️

data -> stores the actual value

next -> points to the next node

📚 CRUD Operations on Linked Lists

Let’s build simple CRUD functions for a singly linked list in C++! (🚀 CRUD = Create, Read, Update, Delete)

Create (Insert Nodes)

Read (Display the list)

Update (Change a Node’s Value)

Delete (Remove a Node)

🌟 Final Thoughts

🔗 Linked Lists may look tricky at first, but once you master them, you’ll be ready to understand more powerful structures like Stacks, Queues, and even Graphs! 🚀

🌱 Mini Challenge:

Build your own linked list of your favorite songs 🎶

WHAT THE FUCK DO YOU MEAN C++ DOESN'T HAVE A SPLIT FUNCTION

[tarffie]

me finally diving into cpp programming making my first game idea, after looking the stuff I need to go through this is my only reaction

[mimimicpp]

Hi all.

Today I want to share the result of many days of work.

I finished making a character input field for my application. And although some text editing capabilities are not available, the required minimum is present.

The following text editing options are currently available:

Typing.

Deleting characters using the backspace key.

Moving the carriage between characters.

Selecting characters using the Shift key.

Copying, cutting, pasting characters using the keys Control + C, Control + X and Control + V. Using the clipboard.

The next thing I want to do is read some books about C++. And then continue working on the project.

POINTERS introduction

#include <iostream> using namespace std; int main(){ /* int n = 5; cout << n << endl; output: 5 */

// is for a comment line and /**/ is for multiple line comments //I make it like this so you can paste it immediately into a compiler //variable - &address - *pointers. //START //just like variable, a pointer is a container as well, storing an address (a memory location) //n is a variable meaning that it is a container storing certain value //because it's a container, it has it's address inside the memory, a physical location //in order to check the location / which address :

/* int n = 5; cout << &n << endl; output: 006FFD64 */

//because it's not always fun to remember long address numbers, so we give them names - variables. we create a pointer to name an address and easily access it.

//POINTERS //how to create a pointer holding address of our n variable:

int n = 5; cout << &n << endl;int* ptr = &n; cout << ptr <<endl; //in order to indicate that you're creating a pointer, use * star (int*) //then give it a random name (ptr) //assign it (to ptr) the address of our n variable which is = &n (= assign)(& address)(n variable) cout << *ptr << endl; // a star * before the pointer's name will only reference the pointer and then find the VALUE of the ADDRESS //which is our original variable n //basically we're asking for the value 5, not the address 006FFD64 //CHANGE THE VALUE (5) stored in the pointer ptr address: *ptr = 10 ; //a star * means access the memory location and (=)assign a NEW (10) value //let's check if it's now 10 instead of 5 cout << *ptr <<endl; cout << n ; //both *ptr and n now show 10

//NOTES //pointer has to be of the SAME TYPE as the variable it is pointing to //int pointer to int variable, not int to float //char pointer to char variable, bool pointer to a bool variable, etc //you can't assign a value to a pointer, it has to point to an address //first create a (example) variable to store that variable's & address to the pointer //pointers are problem solvers and not the casual way it's used in these examples system("pause>0"); return 0; }

🌟 Understanding Arrays: A Beginner’s Deep Dive! 🌟

Hey Tumblr friends 👋

Today I want to break down something super important if you're getting into coding: Arrays. (Yes, those weird-looking brackets you've probably seen in code snippets? Let’s talk about them.)

So... What Exactly Is an Array? 🤔

Imagine you have a bunch of favorite songs you want to save. Instead of creating a new playlist for each song (chaotic!), you put them all into one single playlist.

That playlist? That’s what an Array is in programming! 🎶✨

An array is basically a container where you can store multiple values together under a single name.

Instead of doing this:

You can just do:

Why Are Arrays Useful? 🌈

✅ You can group related data together. ✅ You can loop through them easily. ✅ You can dynamically access or update data. ✅ You keep your code clean and organized. (No messy variables 👀)

How Do You Create an Array? ✨

Here's a simple array:

Or create an empty array first (you must specify size in C++):

Note: C++ arrays have a fixed size once declared!

How Do You Access Items in an Array? 🔎

Arrays are zero-indexed. That means the first element is at position 0.

Example:

Changing Stuff in an Array 🛠️

You can update an item like this:

Looping Through an Array 🔄

Instead of writing:

Use a loop:

Or a range-based for loop (cleaner!):

Some Cool Things You Can Do With Arrays 🚀

In C++ you don't have built-in methods like push, pop, etc. for raw arrays, but you can use vectors (dynamic arrays)! Example with vector:

Quick Tip: Arrays Can Store Anything 🤯

You can store numbers, booleans, objects (structures/classes), and even arrays inside arrays (multidimensional arrays).

Example:

Real-World Example 🌍

A To-Do list:

Output:

👏 See how clean and readable that is compared to hardcoding every single task?

🌟 Final Thoughts

Arrays are the foundation of so much you'll do in coding — from simple projects to complex apps. Master them early, and you'll thank yourself later!

🌱 Start practicing:

Make a list of your favorite movies

Your favorite foods

Songs you love

...all in an array!

1/100 Days of C++: Introduction to Compiler, Linker, and Libraries

Hello reader, welcome to 100 Days of C++ series. In my previous post on 4 Main Reasons Why I am moving to C++ from Python, I expressed my views on how C++ programming language is more convenient for me as an automobile engineer. Not that Python is bad, I am still a fan of Python. But when you need a real-time execution, when a delay of a few hundred milliseconds is of drastic significance, C++ is…

Entry one: A refreashers in code

Hello I am Maxa Coda,

This is a journal of my progress relearning to code. Today I started from scratch learning C++. Thought I have do coding with C++ before and even made some applications with it. However afer yonks of not pratice and kinda forgetting some thew stuff I originally learnt I thought it would be a good idea to have a refeasher.

So I made so very basic console apps even with some user inputs.

So why I'm doing this? I want to work towards making my own simple game/application and not only upskill but also improve my current skillset.

Do I have a plan/project in mind? I do want to make a game, got a 2D side scroller in mind however one step at a time. I might do a few non game projects first. Will update as we go.

Signing off,

Maxa Coda
