Write a complete C++ program with the two alternate functions specified below, each of which simply triples the variable count defined in main . Then compare and contrast the two approaches.

These two functions are

a)function tripleByValue that passes a copy of count by value, triples the copy and returns the new value and

b)function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias (i.e., the reference parameter)
