Student s1("zhnangfei");
Student s2("zhaoyun");
(s1.*pwho)();
Student* ps = &s2;
(ps->*pwho)();
//指向静态成员函数的指针
int (*padd)(int,int) = Student::s_add;
//int (Student::*padd1)(int,int) = Student::s_add;错误的写法
cout << padd(100,200) << endl;

}
成员函数的指针(即函数指针):
返回类型 (类名::*指针名)(形参类型) = &类名::成员函数名(注意类名前一定要加取地址符&,不然报错)
指向静态成员函数的指针(还是函数指针):
返回类型 (*指针名)(形参类型) = Student::s_add(注意类型前面可以不加&也可以加)
