每当我运行代码时，输出似乎都是正确的。但是，尝试输入"猜测"只会循环以前输出的内容。我似乎无法弄清楚是什么原因导致这种情况发生，因为我的同事发给我的示例代码中，它运行良好。此外，我不知道我会把代码的一部分放在哪里以减少剩余的遗漏数量，因为每当我尝试添加它时，它只会降低每个不匹配的字母的这个数字。(请记住，我对 c++ 还比较陌生(。

如评论中所述，您的主要问题是您没有将用户输入转换为大写。由于您还想通过每次猜测更新分数，因此我将创建一个函数来检查匹配项，替换下划线，如果没有匹配项，则返回 1，如果匹配，则返回 0。这似乎是倒退的，因为 0 通常表示失败，但您可以使用此值来更新分数：
int checkLetter(string& source, string& underscores, char c)
{
if (!isalpha(c)) return 0;
c = toupper(c);
int return_value = 1;
for (auto i = 0; i < source.length(); i++) {
if (c == source[i]) {
underscores[i] = c;
return_value = 0;
}
}
return return_value;
}
您的主循环变为：
do {
display(phraseUND);
cout << "Enter a letter: n";
cin >> guess;
chances -= checkLetter(phrase, phraseUND, guess);
cout << "______________________________________________________________" << endl;
cout << "Game Over After " << chances << " incorrect guesses!" << endl;
cout << "Category: " << category << endl << "Phrase: ";
} while (phraseUND != phrase && chances > 0);
请注意，我还更改了 while 条件以在所有猜测用完后退出。
