返回信息流遍了个小程序 试验成员函数指针 结果提示报错 是不是vc语法有变化？
#include <iostream>
using namespace std;
class Mammal
{
public:
Mammal(){HowMany ++;cout << "the number of Mammal is "<< HowMany<<endl;}
~Mammal(){HowMany--;cout << "the number of Mammal is "<< HowMany<<endl;}
void Getage() const {cout<< "it's age is " << itsAge<<endl; }
static void GetNum() {cout << "Now the number of Mammal is : "<< HowMany<<endl;}
private:
int itsAge;
static int HowMany;
};
int Mammal::HowMany=0;
int main ()
{
const int MaxNum=3;
void (Mammal::*pget)() const=0;
pget=Mammal::Getage; // 这里提示说要加个&
Mammal a; //提示说 error C2039: 'pget' : is not a member of 'Mammal'
a.pget;
a.GetNum();
return 0;
}
