Preface

This is a small guessing program , You can choose ：“ scissors , stone , cloth ”, The computer randomly selects “ scissors , stone , cloth ”, The computer referee decides to win or lose , Announce the result of the game , And give the winner extra points .

One 、 The code is divided into the following files

Two 、 The following are listed respectively 8 The contents of a file

1.main.m

#import <Foundation/Foundation.h>
#import “Judge.h”
int main()
{

r1->_name = @“ Afar dog ”;
Judge *j1 = [Judge new];
j1->_name = @“ Black whistle ”;
while(1)
{
//1. Players punch
[p1 showFist];
//2. Robot punches
[r1 showFist];
//3. The referee announced the result of the match , And give the winner extra points
[j1 judgeWithPlayer:p1 andRobot:r1];
