Window stay!

I know how to get the window to close when you press a letter and then enter but is it possable to have it close when you press escape?

#include <stdio.h>
#include <conio.h>

Code:

---

int main()
{
char c;
        while (c!='q')
        {
        c=getch();
        printf ("%i",c);
        }
        return 0;
}

---

Here's a horrible little bit of code I threw together that may give you an idea. You may be particularly interested in the number that appears when you press esc.
q exits :)
