Why do we use getch() in c++

Answer 1

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.

Answer 2

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.

Answer 3

To make the screen of outbuts remain const
