Function getch in C program prompts a user to press a character. It doesn't show up on the screen. Its declaration is in 'conio.h' header file. The function is not a part of standard C library.
C programming code for getch
#include <stdio.h>#include <conio.h>
int main()
{
printf('Waiting for a character to be pressed from the keyboard to exit.n');
getch();
return0;
}

When you run this program, it exits only when you press a character. Try pressing num lock, shift key, etc. (program will not exit if you press these keys) as these are not characters.
Try running the program by removing getch. In this case, it will exit without waiting for a character hit from the keyboard.
How to use getch in C++
#include <iostream.h>
#include <conio.h>int main()
{
cout <<'Enter a character';
getch();
}
Using getch in Dev C++ compiler
Function getch works in Dev C++ compiler but it doesn't support all functions of 'conio.h' as Turbo C compiler does.
Function getchar in C

A common use of getch is you can view the output (if any) of a program without having to open the output window if you are using Turbo C compiler or if you are not running your program from the command prompt.
Conio Library In Mac
Hello all,
I am currently in week 7 of an 18 week C course and, over the past several weeks, I have had several problems with the examples given by my teacher. Some of you may remember this thread.
Once again, I have come across a situation where the example code, supplied by my teacher, works for the rest of the class (using Dev-C on Windows98 machines) but doesn't work for me (using MacOSX 10.4.5 and Xcode 2.2).
The problem stems from the header file <conio.h>. Whenever this is included in any example, Xcode throws up an error at compile time (technically, I guess it's GCC that throws up the error).
Now, true to form, my teacher absolutely insists that, like the fflush(stdin) function (see the thread I linked to above), the <conio.h> header file is completely ANSI compliant. Based on previous form, I am a bit skeptical...in the same way that the Pacific Ocean has a 'bit' of water in it.
So, in the interests of clarification, can anyone tell me...
1) Whether or not <conio.h> is a standard ANSI header file?
2) What functions <conio.h> might be included for. I suspect that it might be getche() or getch() (I don't know what the difference is between those two, by the way. Any illumination would be appreciated), because whenever one or both of those pop up in an example, the <conio.h> header file is included.
Thanks,
TV
