Programming exercise

1. Write a program to read in a character using a loop, and display the character in its normal "char" form. Also display it as a decimal number. Check for a dollar sign to use as the stop character. Use the "getch" form of input so it will print immediately. Hit some of the special keys, such as function keys, when you run the program for some surprises. You will get two inputs from the special keys, the first being a zero which is the indication to the system that a special key was hit.
