/* Title     - Triangle Formulas
 * File name - Lab05
 * Programmer- 415 Erich Musick
 * IPO       - Input - The user inputs the real number lengths of three sides of
                a triangle.
               Processing - The program calculates the area and perimeter using
                the values entered by the user and the formulas for perimeter
                and for area.
               Output - The lengths of the three sides, the perimeter, and the
                area are printed on the user's screen.
