CS 121 LESSON 6: OVERLOADED FUNCTIONS
NATIVE CODE VERSION


Ron Kessler
Created 1/4/2017

This solution introduces overloaded functions. This allows us to use several functions
of the same name but with a differenct signature.




Run with CTL-F5

//this time the function is designed with 2 parameters AND a return type
