Define a class for a type called Counter. An object of this type is used to count things. Include a default constructor that sets the counter to zero and a constructor with one argument that sets the counter to the value specified by its argument. Write member functions to increase the value by one $($called increment$)$ and decrease the value by one $($called decrement$),$ don't let the value go below zero. Write a member function $($print$)$ that prints out the value of the counter.

Here's a driver program that you should include to test your class.
