c++ - 剪刀石头布游戏c++

Question

石头剪刀布游戏 c++ 不显示 cout 来告诉谁赢得了比赛，我不知道出了什么问题，为什么程序不显示 cout。请告诉我出了什么问题、如何解决它以及为什么会发生，我认为 cstdlib 在那里什么也没做。

Objective: To score the rock-paper-scissors game. If the user enters invalid input, your program should say so, otherwise it will output one of the above results.

#include <iostream> 
#include <cstdlib> 

using namespace std; 

int main() 
{ 
    string pone; 
    string ptwo; 
    string r; 
    string p; 
    string s; 

    cout << "Rock, Paper, Scissors Game\n"; 
    cout << "\nPlayer One, please enter your move: ('p' for Paper, 'r' for Rock, 's' for Scissor)";  

    cin >> pone; 

    cout << "\nPlayer Two, please enter your move: ('p' for Paper, 'r' for Rock, 's' for Scissor)"; 

    cin >> ptwo; 

    if (pone == ptwo) 
    { 
        cout <<"\nThere is a tie"<<endl; 
    } 

    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"; 
    } 

    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"; 
    } 

    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"; 
    } 

    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"; 
    } 

    if ( ptwo == s && pone == r) 
    { 
        cout <<"\nScissors cut paper, player 1 win"; 
    } 
    else if (ptwo == s && pone == p) 
    { 
        cout <<"\nRock smashes scissors, player 2 win "; 
    } 

    return 0; 
}

Answer 1

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“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
