/*Program Name: Homework#6 Rectangle Area.cpp
Programmer: Caleb Cohen

Version: 1.3
Description: Rectangle Area

Write a C++ program to get the user data for a rectangle and to calculate area of the rectangle. Your job is to complete the program. When it is complete, the program will ask the user to enter the width and length of a rectangle and then display the rectangle’s area. The program calls the following functions, which have not been written:
• getLength – This function should ask the user to enter the rectangle’s length and then return that value as a double .
• getWidth – This function should ask the user to enter the rectangle’s width and then return that value as a double .
• getArea – This function should accept the rectangle’s length and width as arguments and return the rectangle’s area. The area is calculated by multiplying the length by the width.
• displayData – This function should accept the rectangle’s length, width, and area as arguments and display them in an appropriate message on the screen.
Overload getArea function to calculate area of a rectangle and a circle. You can use getWidth function to get the side of a square and radius of a circle.*/
