C++ Get Started

🚀 Getting Started with C++

Ready to write your first line of C++ code? You’re in the right place! In this guide, you’ll set up your computer and run your first simple program: Hello, World!

Let’s jump in and make that computer talk to us in C++! 😄

💻 Step 1: Install a C++ Compiler

To run C++ programs, you need a compiler. Here are some options:

  • 🪟 Windows: Install Code::Blocks with MinGW
  • 🍎 Mac: Install Xcode Command Line Tools using xcode-select --install
  • 🐧 Linux: Use the terminal: sudo apt install g++

🛠️ Step 2: Choose an Editor

You can write C++ code in any text editor, but it’s best to use an IDE or smart editor:

  • Code::Blocks (easy for beginners)
  • Visual Studio (powerful but heavier)
  • VS Code (lightweight and flexible)

👨‍💻 Step 3: Your First C++ Program

Let’s write the classic “Hello, World!” program. This is like saying “Hi!” to the programming world.

#include <iostream>
using namespace std;

int main() {
    cout << "Hello, World!" << endl;
    return 0;
}

Try It Now

🔎 What’s Happening Here?

  • #include <iostream> – Includes input-output library
  • using namespace std; – So we don’t have to write std:: before things like cout
  • int main() – The starting point of every C++ program
  • cout << "Hello, World!" – Prints text to the screen
  • return 0; – Says “all good” when the program ends

✅ Output:

Hello, World!

🎉 You’re Officially a C++ Programmer!

That’s it! You wrote your first C++ program. It may seem small, but this is how every great programmer started — one line at a time. 🚀
