Do these problems from the text:
Chapter 9, problem 6, 7, 11

A.  Write a function that swaps two float variables.  To make sure that
    you understand what this function should do, consider this program:
    int main()
    {
        float f1(1.0);
        float f2(2.0);

        cout << f1 << " " << f2 << endl;
        swap(f1, f2);
        cout << f1 << " " << f2 << endl;
        return 0;
    }
    The output of this program should be 
        1.0 2.0
        2.0 1.0

B.  Write a function that takes a float array as a parameter, and returns
    the max and min of the elements in the array.  (Recall that if a
    function needs to return more than one value, then it must return them
    in reference parameters.)  Also write the function prototype.
