getchar():- this function returns a character that has been recently typed. the typed character is echoed to the computer screen. after typing the appropriate character the user is required to press enter.

getch():- This function also returns a character that has been recently typed, bet neither the user is required to press enter key after entering the character nor the typed character echoed to the computer screen.

getche():- the advantage of this function over getchar() is that as soon as the user types a character, the character is immediately accepted, i.e. the user is not required to press enter key after typing a character.
