This is a simple rock, paper, scissors game using the c++ programming language. The program basically ask the user to enter there choice and compare it with the computer's choice and determine the winner based on the comparison. An example of a simulation would be that if the user chose rock and the computer chose paper, the computer would be the winner because paper covers rock.
