带有字符串的C ++ if语句只给出一个答案

Question

所以，我试着写一个文本冒险的东西，每当我尝试将一个字符串与一个消息进行比较时，无论我写什么，我都会得到相同的输出...我已搜索并搜索，但不能找到答案......我有使用Java，LUA和一些HTML编程的经验...也许我试图做的事情与Java的方式太相似了？好吧，这里有一些代码可能最终有所帮助。

string sex;

cout << "Would you like to be a boy or a girl?" << endl;
cin >> sex;
cout << sex;
//statement to declare what you are...
if (sex == "boy" || "Boy"){
    cout << "You have chosen to be a boy!" << endl;
}
else if (sex == "girl" || "Girl"){
    cout << "You have chosen to be a girl!" << endl;
}
else{
    create();
}

任何形式的帮助将不胜感激。谢谢。

Answer 1

变化

if (sex == "boy" || sex == "Boy"){
    cout << "You have chosen to be a boy!" << endl;
}
else if (sex == "girl" || sex == "Girl"){
    cout << "You have chosen to be a girl!" << endl;
}

到

if (sex == "boy" || sex == "Boy"){
    cout << "You have chosen to be a boy!" << endl;
}
else if (sex == "girl" || sex =="Girl"){
    cout << "You have chosen to be a girl!" << endl;
}

原因是if (sex == "boy" || "Boy")语句，第二部分总是评估为真。
