石头剪刀布游戏 c++

这是你的问题：

if (pone == r && ptwo == p) 
{ 
    cout << "nPaper wraps rock, Player 1 win"; 
} 
else if (pone == r && ptwo == s) 
{ 
    cout << "nRock smashes scissors, player 1 win"; 
} 
//etc etc

将这些"r"、"p"和"s"放在引号中，如下所示：

if (pone == "r" && ptwo == "p")
//etc etc

你应该很好

你应该给 r、p 和 s 分配一些值

宁愿

r = "r";
p = "p";
s = "s";

希望这有帮助。

这有点晚了，但是...

这是我的程序。我使用了代码的 if elseif 部分，并发现了它的问题。 您重复 2/3 秒的代码两次

****这部分****

if ( pone == r && ptwo == p) 
    { 
        cout << "nPaper wraps rock, Player 1 win"; 
    } 
    else if (pone == r && ptwo == s) 
    { 
        cout << "nRock smashes scissors, player 1 win"; 
    } 

而这部分

if (pone == p && ptwo == r) 
{ 
    cout <<"nPaper wraps rock, player 1 win"; 
} 
else if ( pone == p && ptwo == s) 
{ 
    cout <<"nScissors cut paper, player 2 win"; 
} 

这是我的代码版本，（这是一个准备运行的完整程序）希望这对:)有所帮助
