What is the difference between "getch" and "return"?

[sammyboy]

I have tried to find out the difference between "getch" and "return" but i didn't get anything yet.

They are completely unrelated, to be frank.

return is a keyword which, in broad terms, prepares a value for the calling function to use or store in a variable, and effectively ends the function at that point.

int myrandom(void)
{
   return 4; // value chosen by a fair die roll - guaranteed completely random
}

getch() is a non-standard input function, which if used, may affect the portability of your codebase. You will either be targeting windows or another platform with some version of a curses library. References for these common implementations are below:
_getch, _getwch
getch(3): char from curses terminal keyboard - Linux man page

Not to appear condescending, but how can you not find differences between the two? What code were you using as reference?
