Instructions: Please create a CH+ program to solve the following problem. Submit electronic (Canvas Dropbox) copies of your program source code and two or more sample runs to me by the deadline. Late submissions will not be accepted. Documentation requirements follow the problem specification. 1. Write a program that prompts a user to enter the lengths of the sides of a triangle, classifies the triangle as equilateral, isosceles, or scalene, and computes the area of the triangle. The program begins by displaying the purpose of the program, then prompts the user to enter the lengths of the three sides. It then determines if the sides form a triangle. If they do not, the program displays a message informing the user that the sides do not form a triangle and ends. If they do, the program determines if the triangle is equilateral (3 equal sides), isosceles (2 equal sides), or scalene (no equal sides). It then computes and displays the area of the triangle, rounded to two decimal places. As usual, your program output should resemble the sample runs at the end of this document. Notes: The values for three sides form a valid triangle if the sum of the lengths of any two sides is greater than the length of the remaining side. The area of a triangle can be computed from its sides using the following formula (known as Heron's Formula): area = Vs* (s - a). (s -b)*(s - c) where a, b, and c are the lengths of the sides, and s is equal to half the sum of the sides (i.c., half the perimeter). The use of logical operators to test for valid side lengths is required for this assignment. Test your program using whole number values for the lengths of the sides, but make the variables that store the lengths of the sides type double. If you do not, you may encounter unexpected results.

Documentation Requirements: Each program source code file must have a header at the beginning of the program containing the following: Name of author, PSU e-mail address of author, name of course, assignment number and due date, name of file, purpose of program, compiler and operating system used, references Example: . Author: Wanda Kunkle E-mail: wmk12@psu.edu Course: CMPSC 121 Assignment: Lab 5 Due date: 2/26/2021 File: TriangleTypeTester.cpp Purpose: This program prompts the user to enter the lengths of three sides of a triangle. If the lengths form a triangle, the program classifies the triangle as equilateral, isosceles, or scalene, then computes and displays its area; otherwise, it displays an appropriate error message and ends.
