Invisible Keystrokes

**Frog22** · 08-19-2002

I am new to C++ and was wondering how you input, without what your typing being displayed on the screen, if this is already on the board I apologize, i couldn't find it.

I am using visual C++ 6.0
Example:
when using the "cin" command out of the iostream header;
what you are typing is displayed as you type it, I would like to use
this for inputting passwords.

thanks alot

p.s great site, excellent source for great links, and code;

You need a non-standard function to do that. It involves getting unbuffered keyboard input.

If you have it, you could use getch() (conio.h if you're using Windows).

Code:

#include <stdio.h>
#include <conio.h> // getch()

int main()
{
	int input;
	printf("Enter a number: ");
	while ((input = getch()) != '\r')
		putchar(' ');
	return 0;
}

You could of course make function that does that work for you.
