Programming Project 4 of Chapter 6 on page 341 of the Savitch text.
Except that we provide you with the names of the class members and
the test program. You must define the class, including pre- and 
postconditions on the member function prototypes and the definitions
of the member functions. You will turn in one complete program
that includes your class definition, the main that we provide below
and your definitions of the member functions.

Hint: If you understand the basics of classes, this is easy.

member function names:
    increment  -- increments the counter
    decrement  -- decrements the counter
    get_count  -- returns the current value of the counter
    output  -- outputs the current value of the counter


main for your program is below:


int main()
{
    CounterType c1, c2(100);

    c1.output(cout);
    cout << " should equal 0.\n";
    c2.output(cout);
    cout << " should equal 100.\n";

    c2.output(cout);
    cout << " should equal " << c2.get_count() << endl;

    c2.increment();
    c2.output(cout);
    cout << " should equal 101.\n";

    c1.decrement();
    c1.output(cout);
    cout << " should equal 0. (Better not be -1.)\n";
    c2.decrement();
    c2.output(cout);
    cout << " should equal 100.\n";

    for (CounterType c(1); c.get_count() <= 3; c.increment())
    {
        c.output(cout);
        cout << " ";
    }
    cout << "Hurrah!" << endl;

    return 0;
}
