class Player

string type;
int rank;
public:
virtual void printType()
{
cout<<"Calling Class Player, type is: general Player"<<endl;

//class FootballPlayer: Derived from Player
class FootballPlayer: public Player

class MaleFootballPlayer: public FootballPlayer
{
public:
void printType()
{
cout<<"Calling Class MaleFootballPlayer, type is: Male Football Player"<<endl;
}
void printRank()

cout<<"Calling Class MaleFootballPlayer, Rank is: Male Player rank"<<endl;
}

//class CricketPlayer: Derived from Player
class CricketPlayer: public Player
{

public:
void printType()
{
cout<<"Calling Class CricketPlayer, type is: Cricket Player"<<endl;
}
};
int main(int argc, const char * argv[])
{
FootballPlayer fbplayer;
CricketPlayer crplayer;
MaleFootballPlayer malefbplayer;
FootballPlayer *fbplayerPtr;
fbplayerPtr=&malefbplayer;
fbplayerPtr->printType();
return 0;
}
当我运行程序时，我得到的输出是，
调用类 MaleFootballPlayer，类型为：男足球运动员
我正在创建一个基类指针（footballplayer）并分配给派生类对象（malefootballplayer），它应该调用属于基类的函数（因为它不是虚拟的）并且输出应该是'调用类FootBallPlayer，类型是： 足球运动员'。
希望清除我的概念。
谢谢。
