c++ - 剪刀石头布游戏无法正常运行

Question

我正在上计算机科学的初级类(class)，对于我的下一个项目，我应该制作一个剪刀石头布游戏。

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。

不过，我的问题是，我想测试游戏的运行情况，看看它在这之前是否正常运行。代码编译正确，但一旦我输入我的决定并且计算机输入它的决定，“获胜者”就不正确了。

例如:

玩家选择摇滚

电脑选择剪刀

平局

我想也许我输入了一些 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
{ // else staement OPEN

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

    return(0);
} // else statement CLOSED

            break;
    default:

computer = rand() % 3 + 1;

switch(computer)
{ // Switch statement computer OPEN

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

{ // else if statement8 OPEN

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

} // else if statement8 CLOSED

} // MAIN bracket CLOSED

同样，编码不完整。我还要补充一些东西。

另外，很抱歉，我对编码还是个新手。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......我不知道应该包含或排除哪些部分

修复 if 语句的所有括号
