''' Problem statement:

Write a program that display the following menu:

1.) Calcualte Circumference

2.) Calculate Area

Enter 1, 2 or 0 to exit

In the case of option 1 and 2, the program should then prompt the user for the radius of the circle, perform calculation, and output the result. Then the program should re-display the menu. When option 0 is choosen the program should exit.
