把你崩溃的程序贴上来。

 

应该就是由于缺少copy constructor和copy assignment导致的问题而已。

是啊怎么崩溃的？

没有内存泄露啊，好像也没有空指针访问啊。

今天看了c++对话系列，为什么说下面的类程序会因为内存问题而崩溃呢？

 

#include "xStruct.h" // definition of struct X

class xWrapper
{
    X* xItem;
public:
    xWrapper() : xItem(new X) { }
    ~xWrapper() { delete xItem; }

    void dump() { /* dumps xItem to cout */ }
};
