c++ - 类析构函数中的错误

Question

我刚开始我的容器类，但我已经遇到了问题:

class Container
{
    private:

    string* BasePointer; // The starting pointer.
    unsigned int Capacity; // The number of values the container can hold.

    public:

    Container() // Default constructor.
    {
        Capacity = 1;
        BasePointer = new string[Capacity];
    }

    ~Container() // Destructor.
    {
        delete BasePointer; // Delete the container to prevent memory leaking.
    }
};

我收到错误 Container Classes(26467) malloc: *** error for object 0x100100088: pointer being freed was not allocated。我做错了什么？

XXX ptr = new XXX[size] 应该与数组版本 delete [] ptr 匹配，而不仅仅是常规的 delete。

了解 free store management在 C++ 中，正如 James 提醒我们的那样——遵循 rule of three在这种情况下。
