how write c++ Program ?

Before starting the abcd of C++ language, you need to learn how to write, compile and run the first C++ program.

To write the first C++ program, open the C++ console and write the following code:

#include <iostream.h>

void main() {
clrscr();
cout << "Welcome to C++ Programming.";
