Question: In a triangle, the sum of the lengths of any two sides is greater than the length of the other third side. Write a program triangle.cc that prompts a user to enter the lengths of three sides, check if they form a triangle, and outputs if it is an isosceles, equilateral, scalene,
or right triangle. In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides. An isosceles triangle has two sides of equal length. An equilateral triangle has all three sides with the same length. A scalene triangle has no equal sides.

Test Run 1:
Enter the lengths of the three sides of a triangle -- 12.5 16.2 12.5
This is an isosceles triangle

Test Run 2:
Enter the lengths of the three sides of a triangle -- 3 5 4
This is a scalene and right triangle

Test Run 3:
Enter the lengths of the three sides of a triangle -- 4 1 2
This is not a triangle

Test Run 4:
Enter the lengths of the three sides of a triangle -- 1 1.4142 1
This is an isosceles and right triangle
