Design and code a C++ program that calculates and prints the (D)iameter, the
(C)ircumference, or the (A)rea of a circle, given the radius. The program inputs
two data items: the calculation needed, and the radius of the particular circle.
The program should continue to ask the user for values until the user enters 'Q'
as the type of calculation.
The program should echo print the input data and prompt appropriately. Label
the output and format to two decimal places.
Example:
Enter the calculation type (A, C, D, Q) and
radius:
A
6.75
The area of a circle with radius 6.75 is
143.14
Enter the calculation type (A, C, D, Q) and
radius:
D
4.50
The diameter of a circle with radius 4.50 is 9.00
Enter the calculation type (A, C, D, Q) and
radius:
Q

Use functional decomposition to create a code design. Each math operations
must be in its own value returning function. No GLOBAL Variables are allowed!
Following the guidelines discussed in class, construct a test set for
the program.
