析构函数和成员析构的先后顺序

肖总问到这个问题，写了个程序验证： class Member { public: Member (){} virtual ~Member (){printf(“member destruct\n”);} }; class Base { public: Base (){} virtual ~Base (){ printf(“destruct\n”);} private: Member member_; }; int main(int argc, const char *argv[]) { Base c; return 0; }

结果是：

  destruct
  member destruct

可见析构的时候先调用析构函数，最后析构成员对象。
