Difference betn getch(),getche(),getchar() functions
 

I would like to know what is the difference betn
getchar(),getch(), and getche() functions and which should be used in which conditions.
Thanks,
comwizz. :confused:

Re: Difference betn getch(),getche(),getchar() functions
 

getchar
This is a standard function that gets a character from the stdin.

getch
This is a nonstandard function that gets a character from keyboard, does not echo to screen.

getche
This 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??

>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.

THANK U NARUE......:)

Re: Difference betn getch(),getche(),getchar() functions
 

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 !! :)

What part of post #2 did you not understand?

Re: Difference betn getch(),getche(),getchar() functions
 

getche-displays the character that u have typed on the screen
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)

The experience you get from people posting the same, over and over, in this thread.

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().
