system("PAUSE"); the program waits for you to enter a key
system("CLS"); clears the console or command line terminal

both of makes your program not portable since is operating system
depended

See this about system("pause"); system("cls"); is conceptually similar.

use

getchar(); 
or
cin.get();

instead of system("pause");

Well, the System("pause"); actually a function to the main windows shell, which calls pause.exe, and thereby pauses your program. And just to let you know, the System("PAUSE") method is a bad way of pause your applications...

A good alternative is at:

As for System("CLS") function, it clcears your console applications screen. Basically erasing any user or application genereated output on the screen.

Please let me know if this helps you.
