Assignment 5

Write a program to calculate the sum of the squares, the sum of the cubes,
and the average of the squares of two numbers.  The input will have a code
followed by two numbers.  The code will indicate which function to do:

	Code	Meaning

	 S	Sum of the Squares
	 C	Sum of the Cubes
	 A	Average of the Squares

Input the data from a file and output the result to the screen or to a file,
your choice.  The output should show the data read as well as the results.
Use a function for each of the above (Sum of Squares, Sum of Cubes, Average).

Sample Run:

Input data: S    10   10
   The sum of the Squares is 200
Input Data: C    10   10
   The sum of the Cubes is 2000
Input Data: A    10   10
   The average of the Squares is 100
