Question
This assignment will be to allow the user to input the width and length of a rectangle. The program will then calculate the perimeter of the rectangle and the area of the rectangle. Then, the program will output all four dimensions (width, length, perimeter, and area) in a user-friendly dialog. Finally, the program will ask the user if he/she wants to calculate another rectangle. If so, the program will repeat the above process. If not, the program will say goodbye and stop. CODE COMMENTS PLEASE!
Instructions
In this assignment, students will develop two classes. The first class will contain:
