Where do we use System header file

Question

In Cpp there's a header file named as System, but can you tell me where and why we use this header file, what is the main function of this file

Answer 1

Most commonly used system commands (for Windows OS) are:

system("pause"); // to pause console screen
system("CLS"); // to clear console screen
system("color XX"); // to set console screen foreground and background color

and more which you can find online. :>

The <system.h> header file is a non-standard header provided only by Borland. If you want to use system() function, use <cstdlib>
