使用Visual调试库检测内存泄露

#include using namespace std;   // 使用调试库 #define _CRTDBG_MAP_ALLOC #include #include // 重定义new运算符 #ifdef _DEBUG #ifndef DBG_NEW #define DBG_NEW new (_NORMAL_BLOCK,__FILE__,__LINE__) #define new DBG_NEW #endif #endif   class Simple{ public:     Simple()     {          m_pInt = new int();     }     virtual ~Simple()     {          delete m_pInt;     }       void setIntPtr(int inInt)     {          *m_pInt = inInt;     }   private:     int* m_pInt; };   void dosomething(Simple*& outSimple) {     outSimple = new Simple(); }   int _tmain(int argc, _TCHAR* argv[]) {     _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);       Simple* pSimple = new Simple();       // 这里导致内存泄露     dosomething(pSimple);       delete pSimple;       return 0; }

该程序有两处内存泄露：
