getcharThis is a standard function that gets a character from the stdin.
getchThis is a nonstandard function that gets a character from keyboard, does not echo to screen.
getcheThis is a nonstandard function that gets a character from the keyboard, echoes to screen.
Use
getchar if you want it to work on all compilers. Use getch or getche on a system that supports it when you want keyboard input without pressing [Enter].And note that the return value of all three is
int! You need this to properly check for EOF.

>wat is echo??
In this case, echo means that when you type a character, it prints to the screen so you can see what you typed.

getch() returns the character you typed without displaying it on the screen.
getche() returns the character you typed by displaying(echoing) it on the screen.
and finally, getchar() works similarly and echos the character that u typed on the screen after "enter" is given.
hope you understood!!
all the best !!

getch-just returns the character that had been typed without displaying on the screen.
getchar-works similar as getche but needs an ENTER followed by the char typed...(macro version)

People! this thread has been answered since post number two. And the only thing it could be added to it might be that unless you have a compelling reason to handicap your code with none standard functions, do not use getche() or getche().
