Answer to Question #176826 in C++ for Luna

Question

Write a program that will read an arbitrary number of sets of triangle sides using only integer values. 

1. Prompt the user for sets of numbers and process them until the user submits the numbers 0 0 0, which will terminate the program.
2. For each set of three numbers, the program should print the values read.
3. For each set of three numbers, the program should decide if the numbers represent the sides of a valid triangle.
4. If the numbers could not represent a valid triangle, display an appropriate error message.
5. If the numbers are valid, the program should determine, and display, the:
6. classify sides of the triangle – equilateral, isosceles, or scalene
7. classify angles of the triangle – right, acute, or obtuse

You need to have functions for the following tasks:

1. do the 3 side length form a triangle
2. classify the triangle by side lengths
3. classify the triangle as right or non-right triangle

Sample run:

Provide three side lengths – 0 0 0 to terminate.
