📖 Basic Structure:
Â
#include <iostream> // Header file
using namespace std; // Namespace
using namespace std; // Namespace
int main() { // Entry point
cout << “Hello”; // Output
return 0; // Exit
}
Â
📌 Concepts Explained:
- Header File → Provides functions (iostream = input/output)
- main() Function → Program starts execution here
- Namespace → Avoids naming conflicts
