修改后的代码如下：

#include 
using namespace std;
#define DELETE_OBJECT(Obj) \
        {\
        if (Obj) \
            {\
            delete (Obj); \
            (Obj)=NULL;\
            }\
        }

输出结果：

Briefs:PoDeQiuKu
Pants:BuHeShenDeKuZi
Coat:ZangDeWaiTao

Boss Dressing
Underware:GanJinDeQiuYi
Briefs:HeShenDeQiuKu
