The function "getchar()" is somewhat like "getch()" function which reads a single character from the user .. this is normally used in some kind of loop .. so when any key from keyboard is presses, its code is returned by this function, which then you can use as per your needs.

The "Stdin" means the standard input device which is normally "Keyboard" .. "Stdout" means Standard Output Device which is "Monitor"
