c++ - 编译器错误C2541- 'delete' : delete : cannot delete objects that are not pointers

Question

我写了这个课:

class StaticList
{
   private:
   int      headFree;
   int      headList;
   int      locNew;
   StaticListNode* listNodeArr;

   public:
   StaticList(int numberOfElements);
   ~StaticList();

   void addToStaticList(int ComputerNum);
   int getHeadList();
   int getHeadFree();
   StaticListNode* getListNodeArr();
   void show() const;
};

然后进行动态分配:

StaticList::StaticList(int numberOfElements)
{
   headFree = 1; //Because the first headFree is 1 (the 0 cell is dummy)
   headList = -1;
   locNew = -1;

   this->listNodeArr = new StaticListNode[numberOfElements];

   for (int i = 0; i < numberOfElements - 1; i++) 
       listNodeArr[i].setNext(i + 1);

   listNodeArr[numberOfElements].setNext(-1);
}

The problem is that when I try to delete the allocation through the d'tor, it gives me the error:

可能是什么问题呢？我想念什么？

谢谢!

Answer 1

当您在数组中分配n个元素时，array[n]是您无法访问的地方。

当您调用delete或delete[]时，它想释放不是它的内存。

所以

listNodeArr[numberOfElements].setNext(-1);

在 StaticListNode类数组中的无效位置
更改为

listNodeArr[numberOfElements - 1].setNext(-1);

或 0和 numberOfElements之间的正确位置
