Write a program with an overloaded method for doubling the value of the argument. One version of the method should double an int value, and the other version should double a float value. Call both methods to demonstrate that they work.

Write a program with one method that takes an int value, and returns both double and triple that value. You’ll need to use reference parameters.

Modify the program from Exercise 8-2 so that you don’t need to initialize the variables that will hold the doubled and tripled values before calling the method.
