Consider again the triangle classication program with a slightly different specication: The program reads oating values from the standard input. The three values A, B, and C are interpreted as representing the lengths of the sides of a triangle. The program then prints a message to the standard output that states whether the triangle, if it can be formed, is scalene, isosceles, equilateral, or right angled. Determine the following for the above program: Part a: For the boundary condition A+B>Ccase (scalene triangle), identify test cases to verify the boundary. Part b: For the boundary condition A = C case (isosceles triangle), identify test cases to verify the boundary. Part c: For the boundary condition A = B = C case (equilateral triangle), identify test cases to verify the boundary. Part d: For the boundary condition A2 +B2 = C2 case (right-angle triangle), identify test cases to verify the boundary.
