Notes

* The difference between this code and 08-02_keywait1.c are in Line 15 and 16. The addstr() statement is specific here (as opposed to "any key"), and the comparison in the while loop is also specific.

* If you see the "any key" you press appear, and you don't want that key to appear, use the noecho() function before you use getch() to prompt for input.
