C++ First Program

👶 Your First C++ Program – Hello, World!

Let’s write your very first C++ program. This is where your coding journey truly begins! 🚀

📄 The Code

Here’s a simple C++ program that says hello to the world. Classic stuff — but super important!

#include <iostream> // includes input/output stream library

using namespace std; // allows you to use standard features without std:: prefix

int main() {
    cout << "Hello, C++ World!" << endl; // prints text to the screen
    return 0; // signals that the program ended successfully
}

🖨️ Output

Hello, C++ World!

🧠 Let’s Understand the Code

• #include <iostream> – Gives access to input/output functions like cout.
• using namespace std; – Lets you write cout instead of std::cout.
• int main() – This is where your program starts running.
• cout << "..." – Prints text to the console.
• return 0; – Ends the program successfully.

💡 Fun Fact

Every C++ program starts with main(). It’s like the front door where the magic begins! 🪄
