a. Define an enumeration type, , that has the values

b. Write a function, , that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)

c. Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.
