C++ Hangman 交换实际字符的下划线

Question

我正在用 C++ 为 Uni 评估开发 Hangman 游戏，但在用户键入字母后我无法显示隐藏的单词。所以我得到的单词显示为“_ _ _ _ _ _ _”，但是当我键入一个字母时，它不会将下划线替换为实际字母。

game::game() {

words[0] = "strongly";
words[1] = "cheese";
words[2] = "computer";
words[3] = "coffee";
words[4] = "potatoes";         //words that can be in the game
words[5] = "zebra";
words[6] = "extinguisher";
words[7] = "solution";
words[8] = "diligent";
words[9] = "flabbergasted";

numGuesses = 0;

hiddenWord = words[rand() % 10]; //pick a random word from array words

completedWord = hiddenWord;

//for loop for changing the word to underscores
for (int i = 0; i < completedWord.length(); i++) {
    completedWord[i] = '_';

}   

//for loop adding a space after underscore
for (int i = 0; i < completedWord.length(); i++) {
    cout << completedWord[i] << " ";


}

cout << endl;
cout << "Please enter a letter: ";


char guessedLetter;
cin >> guessedLetter;

if (guessedLetter = completedWord[0]) {
    completedWord = guessedLetter;
    //cout << guessedLetter << endl;
    cout << completedWord << endl;


} 

}

我的整个程序分为不同的头文件和cpp 文件。所以上面的代码来 self 的 gameguesses.cpp，它的标题如下:

    class game {
public:
    string words[10];
    game();
    string hiddenWord;
    int numGuesses;

    string completedWord;

};

这就是我实际得到的:

将不胜感激。谢谢!

我看到 2 个问题:

if (guessedLetter = completedWord[0])

该行需要 == 而不是 =。

其次，您仅将猜测与隐藏单词的第一个字母进行比较。您需要编写一个循环来检查每个字母并在匹配猜测的位置进行替换，而不仅仅是在元素 [0] 中。
