Reading and processing input from keyboard

Hi,

I have some questions about how to work with input from the keyboard. This code can read characters from the keyboard and print them:

Code:

#include <stdio.h>

main()
{
	int c;

	c = getchar();

	while(c != EOF)
		{
		putchar(c);
		c = getchar();
		}

	return 0;
}

However, how can I make so that the input isn't displayed to the screen and is also limited to one character each time (so that you don't have to press RETURN) ? Basically what I want is to make a switch statement based on a few characters read from the keyboard.

Thanks in advance.
