当然，也可以用函数来返回char*指针
[cpp] ?
int g_count = 0; ?
? ?
?class OperNew ?
?{ ?
?public: ?
? ? OperNew() ?
? ? { ? ??
? ? ? ? g_count ++; ?
? ? ? ? pC = new char[20]; ?
? ? ? ? memset(pC, 0, 10); ?
? ? ? ? sprintf(pC, "No.%d", g_count); ?
? ? } ?
? ? char* GetChar() ?
? ? { ?
? ? ? ? return pC; ?
? ? } ?
?private: ?
? ? char * pC ; ?
?}; ?
?
这样就能返回自定义的内容了。本次的返回加上了一个构造时候的序号，当然也可以添加时间等。结果如下：

小提示：
将输出文件拷贝到UE中，然后查找泄露行号出现的次数，可以计算出泄露的数目。
