/* 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.

This program will calculate the perimeter and area of any triangle. The user
only needs to enter the real-number lengths of the sides of a triangle. The
program DOES NOT protect against values that do not form a triangle.

Enter the length of side a: 6

Enter the length of side b: 9.5

Enter the length of side c: 5

  Side A       Side B       Side C      Perimeter       Area
----------   ----------   ----------    ----------   ----------
         6          9.5            5          20.5      13.0968
