Question
Description: Write a program that implements a Rock/Paper/Scissors game that allows the user to play the computer (also known as roshambo, possibly originating in 19th century Japan). The program should prompt the user to enter R, P, or S for Rock, Paper, or Scissors, then it should randomly generate the computer's choice and determine who won and display the result. The program should allow the user to continue playing until the user decides to stop, displaying the score (number of times that the computer won, the number of times that the player won and the number of ties.). In this game, Rock beats (breaks) Scissors, Scissors beats (cuts) Paper, and Paper beats (covers) Rock. The program should do error handling on the input values and require the Player to enter R, P, S or Q (for quit.) The program should accept both upper and lower case letters. The program output should look exactly like the examples below, including spacing and error handling.Explanation / Answer
