河內塔在C++中使用面向對象的概念

我已經看到，這個問題已被問到，但不完全從這種方法。我查看了其他線程，並沒有看到我必須採取的方法的解決方案。請原諒我冗長的帖子。我必須從OOP的角度解決這個問題，事情是我想用一個數組來保存用戶輸入的磁盤數量。我沒有看到另一種方式。河內塔在C++中使用面向對象的概念

  **This is my .h file for the class Tower.** 
      #include <iostream> 
      #include <string> 
      #include "Location.h" 

      using namespace std; 
      //Class for the tower 
      class Tower 
      { 
      private: 
       Location _location; 

       public: 
        //Constructor to build object 
        Tower(Location location); 
        //set get functions to set and get values. 
        void setLocation (Location newLocation); 
        Location getLocation()const; 

       }; 

     **This is my location.h file i used an enum datatype to specify the location of each peg.** 

      enum Location 
      { 
       start, 
       middle, 
       last 
      }; 
     **My disk.h file that has the properties of my disks.** 
     using namespace std; 

     class Disk 
     { 
     private: 
      int _diskLocation; 
      int _diskSize; 

     public: 
      Disk(Tower tow1, int sizeOfDisk); 
      void setdiskSize(int); 
      int getdiskSize()const; 
      void setdiskLocation(Tower newTower); 
      Tower getdiskLocation()const; 

     }; 
    **This is my implementation file where I initialized the constructor and its data members.** 
    using namespace std; 

    Tower::Tower(Location location) 
    { 
     setLocation(location); 
    } 

    Disk::Disk(Tower tow1, int sizeOfDisk) 
    { 
     setdiskSize(sizeOfDisk); 
     setdiskLocation(tow1); 
    } 

Finally the main.cpp file. here i make the objects to be used but when i try to pass in the number of disks entered by the user into the array i get the following error. **"Array initializer must be an initializer list"** 
int main(int argc, const char * argv[]) 
{ 

    Tower tower1(start); 
    Tower tower2(middle); 
    Tower tower3(last); 


    int numberOfDisks =0; 

    cout << "Enter number of disks: " << endl; 
    cin >> numberOfDisks; 


    Disk disks[] = new Disk [numberOfDisks] 
    return 0; 
}

我開始認爲使用這種方法無法解決問題。我在互聯網上發現的這個問題的每個解決方案都是通過程序完成的。除了一些其他的語言和編程概念，我還沒有被教過。這是我第二次參加過的編程課。感謝您的幫助。

Disk disks[]和Disk* disks之間的差異。你可以做Disk* disks = new Disk[numberOfDisks];（注意你的例子中缺少的;），但你不能做Disk disks[] = new Disk[numberOfDisks];。瞭解原因，請參閱this post。
