@Nishi
the answer you have posted is wrong..
Getch() and getchar() are two inbuilt functions..
in getch()
the argument to the function is any key on the keyboard,
not necessarily be a character (A - Z).
getchar()
the argument is a character -> alphabet (A - Z)..

Answer / pinky
getchar() is a function call: it reads in a single
character and waits for the user to hit 'enter key' before
reading the character. This line is included because many
compiler environments will open a new console window, run
the program, and then close the window before you can see
the output. This command keeps that window from closing
because the program is not done yet because it waits for
you to hit enter. Including that line gives you time to see
the program run.
getch() returns back on reading any character(a-z) or any
hit to the keyboard.

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.

Answer / barath krishnan
getchar() is very similar to using scanf with %c. The getch() function is normally used in 2 cases
1 To read any character not just numbers and alphabets but any
non white space character ( any key oder dan num/caps/scroll locks or tab keys)
2 To keep reading from a stream of inputs without forcing the user to press enter key at the end of each input unlike getchar()

Getchar() will accept a character from keyboard displays immediately while typing and need Enter key to pressed for proceeding.
Getch() Normally we will use it at the end of the main(). It just accepts a key stroke and never displays it and proceeds further.
Getche() will accept a character from keyboard display it immediately does not wait for Enter key to pressed for proceeding.
__________________________________________________________________
getch() - get character from screen without echo and compiler didn't wait for another key.
getche() - get character from screen and compiler didn't wait for another key
getchar() - get character from screen and compiler wait for another key.
