to blue screen)

The 'e' in getche() fuction means it echoes(display) the
character that you typed to the screen.As against it ,getch
()just returns the character that that you typed without
echoing it on the screen.

Answer / beulah david

Both getch() and getche() are used to read single character
there is very little difference
For Example.....
1.
main()
{
getch();
}
after running the above program

when you press any key, you'll exit from output screen
verify the output by pressing alt+F5

will not show anything
OUTPUT : black screen(nothing is displayed)

2.
main()
{
getche();
}

will show the key you were pressed

OUTPUT : u(the cursor waits for sometime untill you press
any key from the keyboard after pressing it immediately goes
to blue screen)

Answer / ayaskanta

getch is used to get a character from keyboard. once a key
is pressed it goes back to blue screen. In the case of
getche the compiler waits for you to press ENTER after you
have entered another character through keyboard.
