该程序应该如何工作，它将要求用户猜测随机选择的单词。用户将通过放置可能在该单词内的字母来完成此操作。代码将随机选择3个单词，并且当用户猜到其中一个单词时，它将继续移动到下一个单词。如果用户正确地获得了所有3个单词，那么程序会祝贺他们，如果他们弄错了，那么程序就会结束。该程序将检查用户是否正在尝试输入他们已经使用过的信件，并将阻止他们这样做。该程序还将检查该字母是对还是错，如果错误，将给用户一个警告并增加他们的尝试次数。
我已经编写了几乎所有需要的东西，但我遇到了一个错误，在第一个单词之后，如果用户要输入第二个单词中的一个字母，程序就会说出这个单词错了。例如，让我们说第二个词是CIA。我会在控制台输入字母I和A，它会接受它，但是当我输入C时它会告诉我C不在所选单词中并且会增加我，如果我要尝试输入在C再次它将阻止我这样做。尝试调试但我无法明确指出问题。

你的问题似乎是所有三款游戏都使用word1.find(guess)。我还建议创建一个PlayGame(const string& word)函数，以减少重复和bug的可能性。
