Language/Type: C++ recursion return
Author: Marty Stepp (on 2016/07/03)

Write a recursive function named sumOfSquares that accepts an integer parameter n and returns the sum of squares from 1 to n. For example, the call of sumOfSquares(3) should return 12 + 22 + 32 = 14. If your function is passed 0, return 0. If passed a negative number, your function should throw an int as an exception.

Constraints: Your function must be recursive. Do not use loops or data structures.

This is a function problem. Write a C++ function as described. Do not write a complete program; just the function(s) above.
