随机生成的数字结果与用户输入不匹配

-4

我遇到了一个随机生成的数字结果与用户输入不匹配的问题，它只输出第一条语句而不是落在其他位置，如果用户猜错了。随机生成的数字结果与用户输入不匹配

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

using namespace std; 


int main() 
{ 

    int bank = 10; 
    int heads = 0; 
    int tails = 1; 
    char response; 
    string headsTails; 
    int coinToss = rand() % 2; 
    srand(static_cast<int>(time(0))); 


    cout << "Welcome to the coin flip game. It cost a dollar to play. " << endl; 
    cout << "If you guess correctly you will win $2.00 dollars " << endl; 
    cout << "Do you want to play? (Y/N) " << endl; 
    cin >> response; 


    while (toupper(response) == 'Y') 
    { 
     cout << "Your bank is $" << bank << " dollars." << endl; 
     cout << "Enter head or tails (H/T)" << endl; 
     cin >> response; 

     coinToss = rand() % 2; 
     headsTails = coinToss ? "Heads" : "Tails"; 

     if (coinToss == heads || coinToss == tails) 
     { 
      cout << "Winner! The coin flip came up " << headsTails << endl; 
      cout << "Would you like to play again? (Y/N) " << endl; 
      cin >> response; 
      bank += 2; 
     } 
     else 
     { 
      cout << "Sorry, you lose. The coin flip came up " << headsTails << 
endl; 
      cout << "Would you like to play again? (Y/N) " << endl; 
      cin >> response; 
      bank -= 1; 
     } 

    } 
    cout << "Thanks for playing! Your bank is " << bank << endl; 
    cout << "Please come again! " << endl; 
    return 0; 
}

如果你想比较硬币的结果折腾到用户输入，你实际上应该这样做。你现在忽略用户输入。代码的作用并不神秘，你做到了。 – harold

if (coinToss == heads || coinToss == tails)

这个条件是错误的，它会始终为true，因为你coinToss为0或1自己设置。

您必须使用response变量你问用户，是这样的：

int guess = response == 'T' ? 1 : 0; // convert the user input to the same values used throughout the program. 
if(guess == coinToss) 
//won.. 
else 
//lost..

谢谢！我知道这种情况有什么问题，我不知道我没有想到将结果与用户输入进行比较。 – Revved
