getch() is used to make the console wait till a key is pressed. If placed at the end of the program, getch() make the output window to hold till a key is pressed.

Varun Goyal what you said is actually the half use of it. getch() is primarily used to return the ascii code of the key pressed as it is a function with a return value and not void. So actually for returning this value it has to keep waiting untill any key is pressed.
