write a c++ programm to calculate the area and circumference of rectangle.

the structure of of the program is :

1)declare two variables namely height and width

2)initialize the variables by asking the user

3)call the two functions areaRectangle() and circumferenceRectangle() from the main function

4)function calculate the area of rectangle called circumferenceRectangle()

5)write a function to calculate the area of the rectangle called areaRectangle()

6)write a function to calculate the area of the rectangle called circumferenceRectangle()

7)write prototyes for all possible function in code

8)display the result for each operatiom in the functon it self
