Answer 5

For linux, you may use system("clear") ;

I use system("cls") along with goto (primitive combo) to make something like a refresh option. Whenever the user presses the assigned key, the screen is cleared and only the useful part is shown.

Helps create a page like feel, when I use a while loop along with some if elses...

Though this Idea can be considered obsolete by many as I use goto (which is deprecated)...

Answer 6

system cls clears the screen and then goes to the next statement in the program.
