🧪 Simple Test Code

This is a basic C++ program that displays Hello, World! in the output. Perfect to test if everything works:

// Simple C++ Program
#include <iostream>
using namespace std;

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

Explanation:

• #include <iostream> lets you use input/output functions like cout.
• using namespace std; avoids writing std::cout every time.
• main() is the entry point of the program.
• cout << "Hello, World!" displays the message.
