首页 > 解决方案 > 摇滚/纸/剪刀游戏无法正常运行

问题描述

我正在上计算机科学的初级课程,我的下一个项目应该是制作一个石头、纸、剪刀游戏。

游戏还没有完成,因为我仍然需要添加记分和输入建议(哦,我应该更频繁地选择)和循环。

然而,我的问题是,我想测试游戏是如何运行的,直到这一点。代码编译正确,但是一旦我输入了我的决定并且计算机输入了它的决定,“赢家”就不正确了。

例如:

玩家选择摇滚

电脑选择剪刀

这是一个平局

我想也许我输入了一些我的 if 语句不正确,因为我选择的一些答案是正确的(关于谁是真正的赢家),而有些则没有。

但是在回到我的代码并(多次)检查它们之后,它们对我来说似乎是正确的......

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main()

{ // MAIN bracket OPEN

char YorN;
char player;
int computer;

srand(time(NULL));


cout << "****************************************************************************************" << endl;
cout << "**********************************ROCK PAPER SCISSORS***********************************" << endl;
cout << "****************************************************************************************\n\n"<< endl ;

cout << "---Rules of the game is simple. Choose R for Rock, P for Paper, and S for Scissors---\n";
cout << "---Whoever with the most wins, will be crowned victorious ---\n\n";
cout << "Do you think you can beat me? (Y or N): ";

cin >> YorN;
cout << "\n\n\n";

cout<< "NOTE:::: Whenever you're done playing the game, press ( E ) to Exit the game::::" << endl;


if(YorN=='Y' || YorN == 'y')
{ // if statement OPEN

    cout << "\nAlright, lets see what you got! "<< endl;

} // if statement CLOSED

else

    cout<< "\nWow, I beat you without even trying. \nI am VICTORIOUS!!" << endl;

    return(0);

computer = rand() % 3 + 1;

switch(computer)

    case 1:
            cout<< "Computer chooses Rock "<< endl;
            break;
    case 2:
            cout<< "Computer chooses Paper "<< endl;

    cout<< "***Player WINS***"<< endl;

} // eses if statement7 CLOSED

else if(player=='s' || player=='S' && computer==3)
{ // else if statement8 OPEN

    cout<< "***It's a TIE***" << endl;

} // else if statement8 CLOSED

} // MAIN bracket CLOSED

同样,编码不完整。我还得补充一些东西。

另外我很抱歉,我还是编码新手。如果我对我的问题不够彻底或者我在代码页上添加了太多内容,请原谅我......我不知道要包含或排除哪些部分

解决方案


修复 if 语句的所有括号

例子

从:

if(player=='r' || player=='R' && computer==1){

至:

if((player=='r' || player=='R') && computer==1){
