People use System(“PAUSE”) or System Pause c++ because they want the program to wait until they hit enter so they can see their output.

System Pause c++ Work
System Pause c++ frowned upon because it’s a platform-specific hack that has nothing to do with actually learning to program, but instead to get around a feature of the IDE/OS – the console window launched from Visual Studio closes when the program has finished execution, and so the new user doesn’t get to see the output of his new program.
Bodging in System(“pause”) or System Pause c++ runs the Windows command-line “pause” program and waits for that to terminate before it continues execution of the program – the console window stays open so you can read the output.
A better idea would be to put a breakpoint at the end and debug it, but that again has problems.
