Write a program that prompts the user to enter one of the following using the input command. Triangle, square, pentagon, hexagon Define the value of n for the above four cases via a switch/case structure. Then use n to calculate and display the sum of the interior angles in the figure. Send an error message if the user enters something other than above polygons. Show the output for only 1 case
