Area_CircumferenceEx4.txt

/*
This program is number 4 in exercises. The purpose is to reorder the program from sloppy error filled code
to a program that runs succesfully. It gathers user data and determines the area and perimeter for a rectangle,
area and circumference for a circle, and for a cylinder the volume and surface.
