Question

Write a program that plays the popular scissor-rock- paper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Here are sample runs: scissor (0), rock (1), paper (2): 1 Enter The computer is scissor. You are rock. You won. scissor (0), rock (1), paper (2): 2 Enter The computer is paper. You are paper too. It is a draw.

using namespace std;

int main()
