C++ - Function overloading: write two functions with the following prototypes: int overloadthis (double, double, double); int overloadthis (int, int);

Write a main() function with the following function calls: result = overloadthis( a, b, c ) // where each value is an integer result = overloadthis( x, y ) // where each value is a double result = overloadthis( n ) // where n is either an integer or double (you decide)

How do you explain the results?
