需要調試'預期的非限定id之前'）'令牌'，第一次C++用戶

Question

我想C++，仍然學生在uni，無法找到錯誤來自哪裏。有人可以幫忙嗎？

class M() { 
    static bool m() { 
     cout << "Hello, do you want to tell me your name (y or n)"; 
     char answer = 0; 
     int times = 1; 
     while(times < 3) { 
      cin >> answer; 
      switch(answer){ 
       case 'y' : 
        return true; 
       case 'n' : 
        return false; 
       default : 
        cout << "I am sorry, I don't understand that."; 
        times += 1; 
      } 
      cout << "Your time's up."; 
      return false; 
     }  
    } 
} 

int main() { 
    M::m(); 
}; 

Answer 1

這是在這條線：

class M() { 

你不把類名定義後的括號內。將其更改爲：

class M { 

有一些更多的問題與您的代碼（類右大括號，等以後分號），工作代碼看起來像這樣：

class M { 
public: 
    static bool m() { 
     std::cout << "Hello, do you want to tell me your name (y or n)"; 
     char answer = 0; 
     int times = 1; 
     while(times < 3) { 
      std::cin >> answer; 
      switch(answer){ 
       case 'y' : 
        return true; 
       case 'n' : 
        return false; 
       default : 
        std::cout << "I am sorry, I don't understand that."; 
        times += 1; 
      } 
      std::cout << "Your time's up."; 
      return false; 
     } 
     // You need this so you won't get warnings. 
     return false; 
    } 
}; // Don't forget this semicolon! 

int main() { 
    M SomeObject; 
    SomeObject::m(); 
};
