循环增量不起作用

Question

我是编程的初学者,也是论坛的新手.我一直在做一个开始项目,一个Hangman游戏.我正在使用迭代常量numberGuesses来跟踪用户输入了多少猜测.但是,我的程序没有正确迭代,无论出于什么原因我都无法理解.任何帮助是极大的赞赏!

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string userWord = " ";
    char userLetter = ' ';
    int numberGuesses = 0;
    string board1 =
        " -------|\n"
        " |      |\n"
        "        |\n"
        "        |\n"
        "        |\n"
        "        |\n"
        "      -----";
    string board2 = 
        " -------|\n"
        " |      |\n"
        " O      |\n"
        "        |\n"

        cout << "You entered: " << userLetter << endl;

        if (userWord.find(userLetter) != string::npos)
            cout << userLetter << " is in the word to guess." << endl;
        else
            cout << userLetter << " is NOT in the word to guess." << endl;

        numberGuesses++;

    }

    while (numberGuesses <= 6);

    return 0;
}

Answer 1

=是赋值运算符.要检查是否相等,您应该使用==运算符:

if (numberGuesses == 0) {
    // Here -------^
    // (and do the same for the other conditions)
