do-while循环C++

Question

我很新的C++和我的任务，他们要我创建获取用户输入，我已经在这里做了一个功能：（班级列表是一个数组）

public: 
    void userInput() { 

     string enterAgain; 

     do { 

     cout << "Enter the students name: " << name; 
     cin >> name; 

     cout << "Enter the number of classes the student is enrolled in: " << numClasses; 
     cin >> numClasses; 

     for (int i = 0; i < numClasses; i++) { 
      cout << "Enter the class list: " << (i+1) << classList; 
      cin >> classList; 
      i++; 
     } 

     cout << "Would you like to enter again (y for yes): " << enterAgain; 
     cin >> enterAgain; 

     } while (enterAgain == "Y" || enterAgain == "y"); 

    } 

当我运行它，它会要求用户为学生名字后面的他们正在上课的数，但是当它要求用户输入类列表会显示这样的事情：

Enter the class list: 0x7fff536d1b78 

但除此之外，它不会让我输入任何内容。我搜索了几个小时试图纠正这个问题，我希望有人能指出我在纠正这个问题的正确方向。谢谢！

public: 
    void userInput() { 

     string enterAgain; 

     do { 

     cout << "Enter the students name: " << name; 
     cin >> name; 

     cout << "Enter the number of classes the student is enrolled in: " << numClasses; 
     cin >> numClasses; 

     for (int i = 0; i < numClasses; i++) { 
      cout << "Enter the class list: " << (i+1) << classList; 
      cin >> classList; 
      i++; 
     } 

     cout << "Would you like to enter again (y for yes): " << enterAgain; 
     cin >> enterAgain; 

     } while (enterAgain == "Y" || enterAgain == "y"); 

    } 

应为─

public: 
    void userInput() { 

     string enterAgain; 

     do { 

     cout << "Enter the students name: " << endl; 
     cin >> name; 

     cout << "Enter the number of classes the student is enrolled in: " << endl; 
     cin >> numClasses; 

     for (int i = 0; i < numClasses; i++) { 
      cout << "Enter the class list: " << (i+1) << endl; 
      cin >> classList[i]; 
     } 

     cout << "Would you like to enter again (y for yes): " << endl; 
     cin >> enterAgain; 

     } while (enterAgain == "Y" || enterAgain == "y"); 

    }
