Learn C++ Programming – Beginner to Advanced

If you're looking to jump into the world of programming, you've probably heard of C++. It’s one of the most popular and versatile programming languages in the world. From building video games, and software applications, to even creating operating systems, C++ offers an unmatched level of control and efficiency. Whether you're a complete novice or someone looking to sharpen your coding skills, Learn C++ Programming – Beginner to Advanced is your comprehensive guide.

Why Learn C++ Programming?

Before diving into C++ programming, let's explore why learning this language is a great choice. C++ is a general-purpose programming language that’s been around for decades, and it still remains a favorite among developers due to its performance and flexibility. Major companies such as Microsoft, Google, and even game development studios like Epic Games rely on C++ to build high-performance systems.

If you’re thinking about a career in software development, knowing C++ can give you a competitive edge. It's widely used in areas like game development, systems programming, financial tools, and desktop applications. Plus, C++ serves as the backbone for many other modern programming languages, so mastering it can provide a strong foundation for understanding other languages.

Getting Started: The Basics of C++ Programming

Starting with C++ might seem intimidating at first, but trust me, once you get the hang of it, you’ll love how much control it gives you over what happens inside your computer. The Learn C++ Programming – Beginner to Advanced course breaks down the concepts in a simple and digestible way.

1. Setting Up Your Environment

The first thing you’ll need to do is set up your programming environment. Don’t worry—it’s not as complicated as it sounds. You can use a range of free tools like Code::Blocks, Visual Studio, or Eclipse to write and run your C++ code. These Integrated Development Environments (IDEs) will provide everything you need to start coding right away.

2. Understanding Basic Syntax

The syntax of C++ is quite similar to other programming languages like Java and C#, but it has its own unique features. You'll start by learning how to write simple programs using the following basic building blocks:

Variables: Containers for storing data.

Data types: The types of data you can store (e.g., integers, floats, characters).

Operators: Used to perform operations on variables and values (e.g., addition, subtraction).

Control structures: The "logic" of your program, which includes if-else statements, loops, and more.

3. First Program: Hello World

Every programmer's journey begins with writing the simple Hello World program. It’s the quickest way to see how a basic C++ program works.

cpp

Copy code

#include <iostream>

int main() {

    std::cout << "Hello, World!";

    return 0;

}

This small program prints “Hello, World!” to the screen. Seems simple, right? It introduces you to essential concepts like input/output streams and the main function.

Diving Deeper: Intermediate C++ Programming Concepts

Once you're comfortable with the basics, it's time to dive deeper into more complex topics that allow you to harness the full power of C++. In the Learn C++ Programming – Beginner to Advanced course, you'll gradually advance to more intricate features.

1. Object-Oriented Programming (OOP)

One of the best things about C++ is that it supports object-oriented programming (OOP). This paradigm is based on the concept of "objects" that represent real-world entities. Here, you'll learn about classes, objects, inheritance, polymorphism, and encapsulation.

For example:

cpp

Copy code

class Car {

public:

    string model;

    int year;

    void start() {

        cout << "Car started" << endl;

    }

};

int main() {

    Car myCar;

    myCar.model = "Toyota";

    myCar.year = 2020;

    myCar.start();

    return 0;

}

In this snippet, the Car class contains data members and a method that represents the attributes and behaviors of a car. OOP is a powerful way to manage complex programs, as it organizes the code in a way that mimics real-world entities.

2. Pointers and Memory Management

C++ is known for giving developers fine-grained control over memory. While many modern languages handle memory management automatically, C++ requires you to understand concepts like pointers, memory allocation, and deallocation. This might seem tricky at first, but it's a vital skill for optimizing performance.

Pointers, for example, allow you to directly access and modify memory locations:

cpp

Copy code

int num = 10;

int* ptr = &num;  // pointer to the address of num

cout << *ptr;     // dereferencing to get the value at that memory location

3. Data Structures and Algorithms

To write efficient programs, you’ll need to master data structures like arrays, linked lists, stacks, queues, and hash maps. Alongside this, algorithms such as sorting, searching, and recursion play a significant role in improving the performance of your applications.

Advanced C++ Programming: Mastering Complex Concepts

After getting comfortable with intermediate concepts, you’ll be ready to tackle advanced topics that push your C++ knowledge to the next level. The Learn C++ Programming – Beginner to Advanced course covers these thoroughly.

1. Templates

Templates allow you to write generic code that works with any data type. This helps you write flexible, reusable code without duplicating code for different data types.

cpp

Copy code

template <typename T>

T add(T a, T b) {

    return a + b;

}

int main() {

    cout << add<int>(3, 4) << endl;

    cout << add<float>(3.5, 2.5) << endl;

    return 0;

}

This template function can be used to add integers, floats, or any other data type, making your code more versatile.

2. File Handling

File handling is essential for storing and retrieving data. In C++, you can open, read, write, and manipulate files, making it possible to develop complex programs like text editors or data management systems.

3. Concurrency and Multithreading

As you progress, learning about multithreading and concurrency will enable you to write efficient programs that execute multiple tasks simultaneously. This is critical in developing high-performance systems, especially in today's era of multi-core processors.

How Learning C++ Helps Your Career

C++ programming is more than just a technical skill; it's a valuable asset in the competitive job market. By mastering C++ programming, you'll be equipped to work on various exciting projects and career paths, including:

Game Development: Build 3D video games and immersive experiences using C++ and frameworks like Unreal Engine.

Demystifying Object-Oriented Programming: Key Concepts and Principles

Object-Oriented Programming (OOP) is a fundamental paradigm in software development that has revolutionized the way programmers approach problem-solving and code organization. Despite its widespread adoption, many developers still find OOP concepts daunting and challenging to grasp. In this comprehensive guide, we will demystify Object-Oriented Programming by exploring its key concepts and principles in detail, providing clarity and understanding to beginners and experienced developers alike.

1. Objects and Classes:

At the core of Object-Oriented Programming are objects and classes:

Objects are instances of classes that encapsulate data (attributes) and behavior (methods).

Classes serve as blueprints or templates for creating objects, defining their structure and behavior.

2. Encapsulation:

Encapsulation is the bundling of data and methods within a class, hiding the internal implementation details from the outside world:

Encapsulation promotes data abstraction, allowing objects to interact through well-defined interfaces.

Access modifiers such as public, private, and protected control the visibility and accessibility of class members.

3. Inheritance:

Inheritance enables code reuse and promotes hierarchical relationships between classes:

Subclasses inherit properties and methods from their superclass, allowing for code reuse and modularity.

Inheritance promotes the creation of hierarchical class structures, where subclasses specialize or refine the behavior of their superclass.

4. Polymorphism:

Polymorphism allows objects to exhibit different behaviors based on their underlying type or class:

Polymorphism can be achieved through method overriding (runtime polymorphism) or method overloading (compile-time polymorphism).

Polymorphism enhances code flexibility and extensibility, allowing for more modular and adaptable software designs.

5. Abstraction:

Abstraction involves modeling real-world entities as simplified, essential representations in code:

Abstraction focuses on capturing the essential properties and behaviors of objects while hiding irrelevant details.

Abstract classes and interfaces provide a mechanism for defining common behaviors and contracts that concrete classes must implement.

6. Message Passing:

Message passing is a fundamental mechanism in Object-Oriented Programming for objects to communicate and collaborate with each other:

Objects interact by sending messages to each other, triggering method invocations and responses.

Message passing promotes loose coupling and encapsulation, as objects are only aware of each other's interfaces, not their internal implementations.

7. Design Patterns:

Design patterns are reusable solutions to common design problems in software development:

Object-Oriented Programming languages often leverage design patterns to address recurring challenges and promote best practices.

Examples of design patterns include Factory, Singleton, Observer, and Strategy patterns, each serving specific purposes and use cases.

Conclusion:

By understanding the key concepts and principles of Object-Oriented Programming, developers can build more modular, scalable, and maintainable software systems. Whether you're a beginner learning the fundamentals of OOP or an experienced developer seeking to deepen your understanding, mastering these concepts is essential for success in the world of software development. Armed with this knowledge, developers can leverage the power of Object-Oriented Programming to create elegant and efficient solutions to complex problems, driving innovation and progress in the field of technology.

What is the basic fundamental of Java?

Java is a powerful, object-oriented programming language that is widely used in the software industry for building scalable, secure, and platform-independent applications. Whether you are a beginner exploring the world of coding or an experienced developer brushing up on core concepts, understanding the basic fundamentals of Java is crucial.

In this article, we’ll explore the key principles that make up the foundation of Java programming and why mastering them is essential for any developer.

 Why Learn Java Fundamentals First?

Java is not just a language—it’s a comprehensive ecosystem. Grasping the basics helps you write efficient code, debug effectively, and transition smoothly to more advanced topics like frameworks, APIs, and libraries.

Foundational knowledge is often what sets apart a beginner from a confident coder.

 1. Java Syntax and Structure

Every Java program must follow a specific structure and syntax. The code is organized into classes and methods, and Java is case-sensitive. Here’s a quick overview of the structure:

java

public class HelloWorld {

    public static void main(String[] args) {

        System.out.println("Hello, World!");

    }

}

Key Elements:

class: Everything in Java revolves around classes.

main(): Entry point of any Java application.

System.out.println(): Used to print output.

 2. Data Types and Variables

Understanding data types is one of the most fundamental parts of programming in Java. Java is a statically typed language, meaning variables must be declared before use.

Primary Data Types:

int – integers

double – floating-point numbers

char – single characters

boolean – true or false

Variable Example:

java

int age = 25;

boolean isStudent = true;

 3. Control Flow Statements

Control flow dictates how a program runs and under what conditions certain blocks of code are executed.

Main Control Statements:

if, else if, else

switch

for, while, do-while loops

break, continue

Example:

java

if (age > 18) {

    System.out.println("Adult");

} else {

    System.out.println("Minor");

}

 4. Object-Oriented Programming (OOP)

Java is fundamentally an object-oriented language. This means that the design of the program revolves around creating objects from classes.

Core OOP Principles:

Encapsulation – Binding data and methods together

Inheritance – Reusing code from one class in another

Polymorphism – One interface, many implementations

Abstraction – Hiding internal implementation details

Example:

java

class Animal {

    void sound() {

        System.out.println("Animal makes a sound");

    }

}

class Dog extends Animal {

    void sound() {

        System.out.println("Dog barks");

    }

}

Understanding OOP is vital if you want to build scalable and maintainable applications in Java. These principles are taught step-by-step in the Best Java course in Chandigarh, which focuses on both theory and real-time project application.

 5. Java Methods and Functions

In Java, methods are blocks of code that perform a specific task and can be reused.

Method Syntax:

java

public static int add(int a, int b) {

    return a + b;

}

Methods help you:

Break down complex problems

Avoid code repetition

Improve readability

 6. Arrays and Collections

Java provides tools to store multiple values:

Arrays: Fixed-size, same data type

ArrayList, HashMap, HashSet (Collections): Flexible and dynamic

Example:

java

int[] numbers = {1, 2, 3, 4};

System.out.println(numbers[0]); // Output: 1

Collections are particularly useful in real-world Java development where data needs to be stored, searched, or manipulated efficiently.

7. Exception Handling

Errors are inevitable. Java provides a robust exception handling system that ensures your application doesn't crash unexpectedly.

Syntax:

java

try {

    int divide = 10 / 0;

} catch (ArithmeticException e) {

    System.out.println("Cannot divide by zero");

}

Handling exceptions makes your code more resilient and user-friendly.

 8. Java Development Tools

Java developers rely on a variety of tools for writing, testing, and deploying code, such as:

IDEs like IntelliJ IDEA or Eclipse

Build tools like Maven or Gradle

Version control systems like Git

Debuggers and profilers for performance monitoring

Learning how to use these tools early on will help you become an efficient developer.

 Conclusion

The basic fundamentals of Java—from syntax and variables to object-oriented principles and exception handling—are essential stepping stones for every programmer. Whether you aim to build Android apps, enterprise solutions, or web applications, these core concepts are non-negotiable.

If you’re looking to get a solid foundation with hands-on practice and expert guidance, enrolling in the Best Java course in Chandigarh can significantly accelerate your learning journey. These courses typically include project-based learning, resume-building exercises, and mentorship to help you succeed in real-world scenarios.

OOPs concepts with real time examples are frequently used in Java because they promote code reuse while maintaining security.

[crystalelemental]

“hamofjustice: i've definitely wondered if i've poisoned my own experiences by having the "i'm just running through this to get to postgame" mindset and exploring+remembering pretty much nothing on the way there, when imagining oneself in the pokemon world was the most fun part as a kid. it is a little disappointing that you kinda still have to go out of your way to smell the roses and use your imagination though, still towns of 4 houses with people who say 1 line each in 2022.”

I dunno, I prefer it over the opposite, which I’m going to start calling the Breath of the Wild effect, since it’s the only open-world game I’ve directly experienced.  When everything open and there’s technically tons to do but it’s all very repetitive and boring, that’s way worse to me.

I think the real hit has been...as I’ve gotten older, I feel like I’ve had less time for fun.  I can experience older games with the same excitement because I have established concepts and ideas within those games, and that carries over.  But a new game needs that time and energy devoted, that I’m not always willing to invest because I’m tired, or pulled in too many directions by life, and don’t feel like I can dedicate, and then it feels hollow because yeah, it’s four houses with people who say one line each.  It doesn’t feel like as much.  There are also legitimate changes that do simplify things.  Gen 8 is actually a smaller world.  Each route is much smaller that previous games, there are fewer trainer battles, and a lot less side stuff to explore, because the game wanted to streamline its experience to facilitate EXP All by removing situations like Gen 2′s Team Rocket segments that go for 40 minutes of fighting the same four Pokemon.  I can’t say it wasn’t well intentioned, but it does leave a gaping hole where an interested spooky Fae Forest should be, you know?

“3 minutes devoted to a character's vibe is pretty cool in comparison! actually putting stuff like that in the game would be a pretty welcome thing i would not complain about online for wasting my time and would make me enjoy every time i encountered them later more (also, i like that the elite four have been characters you actually know in the games lately, instead of four themed weirdo strangers. sometimes even the champion is some rando who said one line to you before)”

Just calling Diantha right out, huh?  But yeah, I like getting to know these characters.  I think the inverse is also fine though.  Like, FRLG kept the same structure where you really don’t know the E4, but your post-game had stuff like the Four Island bit with Lorelei, and I think that’s great too.  I don’t have to know them at first, but there should be something.  I do like the idea of getting some time to know the gym leaders, and I think the best example we had of that was probably Gen 5, where you met almost all of them in advance of their battle, or their battle was immediately followed a segment learning about their character.  That was great.  I think it’s part of why Gen 5′s cast shines so much.  If they could produce something comparable again, I think people would respond positively.

“(and in the language of pokemon tropes a rando saying one ambiguous line to you basically gives away that they're the champion. if i knew i'd have this much to say i'd just have reblogged it oops)”

You’re fine.  But you’re right, I think it was probably a good move on their part to just...announce who is the Champion.  The mystery was pretty easily solved early on.

“megazardx2: @hamofjustice Well, only Diantha was ever really a “rando” as far as Champions are concerned.”

Hehe, we all know about that one.  Poor Diantha.

“Anyways, I agree; they’ve been putting a lot more effort into making Gym Leaders, E4 members and Champions into actual characters for players to engage and fall in love with for reasons outside of design, which is something I very much appreciate. I mean, the existence of Pokémon Masters is proof!“

I definitely like having character, but on the Masters note...I think it’s nice to have gaps too.  I don’t need to know everything about a character, just enough to work with.  Like...part of the fun of a character like Jasmine or Caitlin for me is that we don’t know everything about them, and have some room for interpretation.  I know some find that bothersome and lacking depth, but I think it can be a nice experience at times, too.

Not Your Average Love Story (SPN x CM)

Sam Winchester x Spencer Reid

Word Count: ~3490

Warnings: Show-level violence, but that’s about it! It’s bizarrely fluffy. 

A/N: My first square for @cmbingo​: “meet the parents.” This is essentially a rewrite of Supernatural 12x01, “Keep Calm and Carry On,” except Spencer and Sam are adorable dorky murder boyfriends. 

Thanks to @fangirlxwritesx67​ for the read-through! 

 When Spencer realizes he’s in love with Sam, he’s on a plane, hoping to make it to Kansas before the sun goes dark. 

He looks out the window at the too-orange light, thinking, this is a weird twist for a love story. He turns that thought over in his mind and realizes: love. 

Oh. 

It takes him by surprise, for some reason, but only for a second. He’s starting to get used to surprises. 

* * *

Spencer has always been self-aware enough to realize that his intellect and his lack of social skills would not make it easy to strike up a traditional relationship. Then, of course, you factor in his obsessive tendencies, his attachment issues, and the stresses of his job, and it’s not actually surprising that he made it past the age of thirty before he fell in love for the first time. Considering how that ended, it’s definitely a surprise — if not a minor miracle — that he’s made it this far with Sam. 

Then again, nothing about their relationship has been predictable. Spencer never guessed he’d meet his future partner while dissecting a dessicated brain. 

Ever since Spencer Reid met Sam Winchester, his life has been one surprise after another. 

* * *

The third unanswered call makes him nervous, but he figures Sam must be asleep, or at least he should be asleep. If Spencer finds himself doing ninety mph in his tiny rental car, it’s mostly because Kansas highways don’t seem to follow the usual laws of physics. They’re flat and endless and eerie in the grey pre-dawn light. 

The moment he opens the door, Spencer knows something is wrong. He spares a wishful thought for his Kevlar, and then he draws his gun, falling automatically into the too-familiar stance as he silently descends the stairs. 

There’s blood on the floor. 

This doesn’t surprise him in the slightest. 

* * *

Spencer tends to spend a lot of time visualizing hypothetical problems and their solutions. He’s good at imagining all the potential outcomes of a particular scenario and calculating their likelihoods based on given variables. He frequently does this at night, instead of sleeping. 

In other words, he worries a lot. 

If he were in a normal relationship he would probably worry about normal things. For example: whether Spencer was misreading the situation, whether it was okay to run a thorough background check on them, and what to wear on a date. What would their first argument be about? What would their parents think of him? What would his mom think of them? 

About thirty-six hours after they met, Sam saved Spencer’s mom from a wraith; first impressions don’t get much better than that. 

The normal worries were rapidly eclipsed by Sam-specific worries. For example: what if he got cursed, what if he got possessed, and were there angels or demons after him this week. Why couldn’t Dean either drive a little slower or get a car with less antiquated safety features? How would Spencer help if Sam got hurt on the job? Should he tell the B.A.U. what he’s been learning about the supernatural? 

He does end up telling them everything; Sam and Dean show up at a crime scene, Hotch almost arrests them, and it turns out that one of the serial killers they’ve been hunting for a decade is actually a skinwalker. 

But the point is that when Spencer sees blood on the floor, he isn’t surprised. He’s visualized this scenario — and several hundred variations on it — before. 

* * * 

He hears a raised voice in the library and takes the steps two at a time. There are two complete strangers there, a blonde woman aiming a gun at a man, and Spencer’s training kicks in before he can figure out why she looks familiar. 

“Federal agent, hands in the air,” he barks. 

He can see the split-second when the woman thinks about turning her gun on him, but she seems to think better of it, and she sets the gun down slowly before putting her hands in the air. 

“Who are you?” the man demands. “What did you do with Sam?”

“What — Sam?” Spencer asks, panic rising in his throat. “Spencer Reid, FBI. Who —” 

“You’re Spencer?” he asks, brow furrowed. 

Spencer realizes: “You’re Castiel.” 

“Whoa, whoa, hey, gun down,” Dean interrupts. “It’s okay! She’s okay, Spence!” 

“Dean? You’re alive?” Castiel grabs him before he can say anything else.  

Spencer lowers his gun slowly. He’s starting to hyperventilate. He wants to know how Dean is still alive, yes, but he’s watching the way they embrace, the smile on Cas’s face and the way Dean’s shoulders seem to drop like he’s relaxing for the first time in a long time, and all he can think about is — 

“Can somebody tell me where the hell Sam is?” Spencer asks, voice cracking embarrassingly. 

“He’s not here,” Castiel says.

The woman looks between Cas and Spencer, eyes wide, and it’s not clear who she’s talking to when she asks, “Who are you?” 

“He’s my —” Dean starts.

Cas cuts him off by saying, “He’s Sam’s —” at the same time Spencer blurts out, “He’s an angel.” 

“Come again?” the woman asks, and when she sees the way Dean shifts nervously, she adds, “Not that, I don’t care about — you said angel?” 

“Angel. You know. Wings, harp.” 

“Not actually,” Spencer tells her, just as Cas scowls and says, “No, I don’t have a harp.” 

“Cas, Spencer,” Dean says, and he pauses, swallowing hard. “This is Mary. Mary Winchester.” 

Spencer and Cas speak in unison again, Cas in a gruff monotone as Spencer’s voice goes squeaky: “Your mother?” 

Of all the things Spencer has worried about, he never thought he would never have to worry about making a bad first impression on Sam’s parents. Sam’s parents are dead. 

Except… apparently not. Apparently Sam’s mom has been resurrected, and Spencer just pulled a gun on her. 

“Nice to meet you,” Mary says softly, with a tentative smile. 

For a second he freezes, staring at her, and his mind starts racing, recalculating, replanning, getting his worrying done after the fact, and Spencer has no idea what to say. He never made a plan for this. 

“Nice to meet you,” he responds, flushing. “Um. Sorry about that.” 

“I’d have done the same thing if I were you.” She smiles, and she doesn’t look much like Sam, but the kindness in her eyes is so very familiar. Spencer’s breath catches. 

“She’s not kidding, shoulda seen the way she pinned me when I tried to introduce myself,” Dean grumbles. Then he turns to Castiel and says, “Tell me what happened to Sam.” 

As Castiel starts to explain the details, Spencer calls Penelope. 

“FBI, office of the brilliant but under-caffeinated,” she says, slightly less chirpy than he’s used to, and Spencer realizes how early it is. Oops. 

“It’s me.” 

“Oh! Boy genius! They did it, huh? Hotch called us back in, like, as soon as the sun came back on, because apparently criminals don’t stop just because the world is ending, or whatever, but he wanted to give you a day at least — hey, are you okay? How’s that handsome lumberjack of yours?” 

“Sam’s missing,” Spencer says without preamble. “I need your help.” 

It takes Penelope approximately a minute to find the car and identify the driver, but the identity of his passenger is a little more elusive. She types away, keys clattering ceaselessly in the background, as Spencer yawns. 

“Got it! Okay, I have a cell number. If you call her, I can track it. You ready?” 

“Dean, give me your phone?” Spencer asks, holding out a hand. “You stay on the line with Penelope. She can tell you as soon as she gets the address.” 

“I can make the call,” Dean says. “I want to have a word with this bitch.” 

“Dean,” Spencer snaps. “First of all, I’m the only person here who’s trained in hostage negotiation. Finding people is literally in my job description.” 

“This isn’t a fuckin’ bank holdup, this is my brother,” Dean retorts. “It’s my job to take care of him.” 

“If you call her a bitch and start in on your threatening macho bullshit, she’s going to hang up, or worse, she’s going to believe you, and then she’ll be trying to get you before you can get to Sam. I know how to talk to people like this. If I can convince her I’m scared, that I’m not a real threat, she might give something away.” 

“But —” 

“Secondly, the only people who know you’re alive are in this room right now, which means you’re our best chance to take her by surprise when we get there, so shut up and let me do my job.” 

“You really think you can find him,” Dean says, and it’s not a question. He holds out his phone with a look of begrudging respect.

“Yes.” 

Spencer thinks, I have to. 

* * *

People aren’t all the same, but if you could quantify the concept of normal, if you could look at it statistically, most people would fall within the standard deviation. Most of their lives take an even, predictable shape, Spencer thinks. There are plenty of other people like them, and they seem to fit with each other, too, interlocking in an easy way that Spencer has always envied. 

Spencer’s got all these awkward uneven edges and strange angles. He’s not normal, and he’s always known that. 

For a long time, he doesn’t think he’ll ever find someone who’ll fit easily, not without changing him, trying to reshape him in some way. He doesn’t want to change, but he gets lonely. Most people (friends, let alone lovers) don’t last long before they get sick of his quirks. Some try longer than others, but one way or another, there’s always some jarring part of him that doesn’t match what they want. 

What if they like to sleep with the windows open, even in the winter? Or if they sleep with the air conditioning cranked up in the summer? Spencer knows he should be better about compromising on little things like that, but he really prefers things a certain way. He knows it’s neurotic. He can’t help it.  

Spencer is used to people staring blankly when he starts talking, but at what point will it drive someone away? When will they stop pretending to care about his Doctor Who opinions? When will they get bored of his info-dumping? 

And then there are the really difficult questions. How does he tell someone he used to be an addict? What if he doesn’t want to tell them about being kidnapped and tortured? What if he does, and then they start asking questions? How does he explain his PTSD, or his nightmares, or his bedtime routine of triple-checking every lock and setting his gun within arm’s reach? 

At first, when he met Sam, Spencer worried about arguments and parents and all the other normal things, but more importantly, he worried about himself. He wondered which of his irregularities would finally make Sam give up on his attempts to fit Spencer into his life. 

Neither of them sleep much, but when they do end up sharing a bed, Sam has his own routine; while Spencer checks the locks, Sam draws warding symbols, lines each window and door with salt, and sets his gun within reach. He likes the windows closed and the thermostat above 68, because, he explains simply, “Lucifer runs cold.” 

Speaking of Lucifer. Sam understands addiction, kidnapping, torture, PTSD, and nightmares, and he doesn’t ask Spencer to tell his stories before he’s ready. Sam has stories of his own. 

Sam also has his own Doctor Who opinions, and those opinions were the cause of their very first argument. Sam is wrong, but Spencer loves that he cares enough to argue. 

The first time Spencer started rambling about serial killers, he noticed Sam frowning and cut himself off, embarrassed, ready to apologize. Sam just pulled out a journal and asked him to repeat what he’d said, so that Sam could do more research on the subject later. 

Sam doesn’t expect him to change. He doesn’t try to re-shape Spencer. His life is just as weird, and by all logic they shouldn’t fit, but they do. And Spencer doesn’t feel any less himself, but suddenly he realizes that he must’ve changed along the way, because he can’t imagine his life without Sam any more; if they can’t find him, his absence is going to tear Spencer apart. 

* * * 

It’s a tense car ride, to say the least. 

Hell of a first impression, Spencer thinks again, glancing at Mary’s pale, worried face in the rearview. 

Castiel and Mary are in the backseat, and they’re trying to make small talk, but Castiel seems to be about as good as Spencer at the whole “casual conversation” thing. Sam’s told him so much about Castiel, Spencer feels like he knows him, but they’ve never actually crossed paths before. 

And then there’s Dean, who’s got his jaw clenched, staring straight ahead. Spencer gives him directions, and he grunts or nods, but he doesn’t say anything else. 

Dean intimidates the hell out of him, but they’ve always gotten along fine, maybe because Spencer’s never yelled at him before. He’s very aware that arguing with Dean Winchester is usually fruitless at best (and deadly at worst), but he’s never been good at holding his tongue when he’s upset. 

“I’m sorry,” Spencer manages to mutter eventually.  

“Huh?” Dean looks at him, frowning. 

“About earlier. I didn’t mean to — um.”

“Nah, it’s fine,” Dean says gruffly. 

“I was upset. I’m sorry.” 

Dean shrugs, and he hesitates before adding, “You were right.” He looks as surprised to be saying it as Spencer is to hear it. 

Spencer blinks at him a couple times before hurriedly saying, “Turn left. There.” 

Cas and Mary are having a quiet conversation about the weirdness of technology, and Spencer is about to join them when Dean speaks up again. 

“Garcia — she said something funny.”

“Uh oh.” 

Dean snorts. “Nah, not like that. Before she hung up, she told me not to worry. Said of everybody she knows, Sam probably has the second-best odds of escaping any poor sap who tries to abduct him.” 

“Second best?” 

“That’s what I said. But apparently that title belongs to you.” 

“I wouldn’t bet on it. All I can do is talk myself out, he’s stronger.” Spencer gives him a crooked attempt at a smile; it feels awkward on his face, but he means it when he says, “He’ll be okay.”

* * * 

The funny thing is, Spencer has been in this situation before. 

When it was Maeve, though, he panicked, because all he could think about was how she must feel: scared, helpless. Spencer has too much empathy sometimes. Imagining Maeve’s helplessness made him feel like he was drowning. 

This is different. He’s not exactly zen about the whole situation, of course; it feels like a piece of him is missing, but he’s clear-headed, because he knows that Sam is anything but helpless. He trusts Sam to take care of himself.  

Aside from the supernatural element, Sam’s job is astoundingly similar to Spencer’s, and he’s astoundingly good at it. The Winchesters have consulted on a couple cases, now, for the B.A.U. (Spencer’s still not sure how Hotch manages the paperwork) and they try to find cases in the same general area as wherever Spencer winds up, so they’ve gotten to work together a few times. Sam’s sheer competence at his job might be the most attractive thing Spencer has ever seen. 

Spencer used to imagine a quiet, mundane romance. He always just assumed he’d find someone whose life was more normal than his, and he was resigned to the stress it would cause in a relationship. He’d forget to call, he’d miss dinner, he’d have to cancel plans and be absent from so much of what constituted a normal domestic life, and his partner would be left at home, alone, all too aware of how much danger Spencer could be in, helpless to do anything about it. 

Instead, Spencer found Sam. Spencer never has to feel guilty about missing dinner, because Sam isn’t at home worrying about him. Sam is out there saving the world. 

Sam is not going to wait for Spencer to rescue him; he might not even need rescuing, at this point. Instead of worrying about what Sam is doing and whether he’s scared, Spencer can focus on his own plan. 

* * * 

He and Dean circle slowly around the house. They spot the entrance to the basement, and Dean almost runs right to it, but Spencer grabs his arm and points to the sigils around the door. 

Spencer notices movement through a window next to the back door, and when they creep up to get a glimpse inside, he sees two women. One is the blonde — the brains of the operation — and the other is stockier, clearly the muscle. 

After a quick conversation in whispers and gestures, Dean sneaks around to the side of the house opposite the basement, and a second later Spencer hears him shout. He waits a couple seconds and glances in the window again, and sure enough, the bigger woman is gone while the blonde is watching something on a computer monitor, looking agitated. Security cameras, maybe. 

Spencer is about to go inside when he sees the blonde start, look around, and grab a cattle prod. Then she’s hurrying toward a door, sliding back a heavy deadbolt, and Spencer sees a dark stairwell that must lead to the basement. 

He slips through the door and follows her. 

For a split-second, the scene in the basement almost stops his heart. Sam is lying on the floor, completely still, his head surrounded by a puddle of blood. 

But before Spencer can really process what he’s seeing, let alone react, Sam is in motion: lashing out, grabbing her by the throat, shoving her against the wall. Spencer descends the stairs quietly with his gun at the ready, trying not to make any noise that might distract Sam right now. 

Sam doesn’t need his help. There’s blood on his damp clothes and his arms are shaking as the blonde goes limp in his grip, but he’s alive; he doesn’t need Spencer’s help, and Spencer isn’t the slightest bit surprised. 

When Sam turns and sees him, he doesn’t look surprised either. He just smiles, all dimples and sparkling eyes in spite of his obvious pain as he limps over. 

“Sorry that took me so long,” Spencer says casually, trying to control his grin. He doesn’t want to holster his gun yet, so he keeps it trained on the woman and hugs Sam one-armed. 

Sam wraps his arms around Spencer, holding on tight. Spencer rests his forehead on Sam’s shoulder, taking a second to breathe as he feels missing pieces sliding neatly into place. 

“Love you,” Sam says, and the words sound like a sigh of relief. He pulls back, and he looks surprised, like he didn’t actually mean to say that out loud. 

Spencer’s about to reply when he sees the woman struggling to her feet, reaching for her cattle prod, and so instead he says, “Look out.” 

Sam steps sideways to give him a clear shot. Spencer shoots her in the thigh and she screams as she falls to the floor. 

“See how you like it,” Sam tells her, with a vicious little smile. 

“I love you too,” Spencer blurts out. 

For a second they both pause, grinning at each other like idiots, their surroundings forgotten.

Then there’s a sound from overhead, and Sam asks hurriedly, “The other one. Did you take her out already?”

“Dean’s got her,” Spencer tells him. “We should check on him, then we can come back down and deal with — Sam?” 

At first he can’t figure out why Sam’s mouth drops open like that, shocked and disbelieving. Then he remembers. 

“Dean’s alive?” Sam asks, a smile spreading slowly over his face. Spencer nods, wrapping an arm around Sam’s ribs, supporting him as he limps gingerly toward the stairs. It feels like he’s forgetting something.

There’s another noise, and then Mary is in the doorway, looking down at them. 

Oh. 

Sam turns to Spencer silently, like he’s waiting for confirmation that she’s real. 

Spencer nods. “Yeah. So — um. Surprise?” 

Sam doesn’t actually seem all that surprised, because… of course he doesn’t. He blinks at Spencer a couple times and then he grins. 

“You met my mom before I did,” Sam says, breathless and amused, and grabs the banister to haul himself up the stairs. Spencer laughs and follows him, smiling to himself. 

It’s not your average “meet the parents” scene, but somehow, it fits Sam and Spencer perfectly. 

Nothing about their love story has been normal. Why start now?
