我有以下程序。当我尝试执行它时,我发现 Allrounder
没有得到有效的名称。知道我该如何解决吗?
#include <iostream>
#include <string>
using namespace std;
class Player
{
std::string playerName;
public:
Player(std::string &playerName) :playerName(playerName) { cout << "Player Constructed\n"; }
void printPlayerName() const
{
std::cout<<playerName<<endl;
}
Player() = default;
virtual ~Player() { cout << "Player Destructed\n"; }
};
class Batsman : virtual public Player
{
public:
Batsman(std::string playerName) : Player(playerName) { cout << "Batsman info added\n"; }
~Batsman() { cout << "Batsman Destructed\n"; }
};
class Bowler : virtual public Player
{
public:
Bowler(std::string playerName) : Player(playerName) { cout << "Bowler info added\n"; }
~Bowler() { cout << "Bowler Destructed\n"; }
};
class Allrounder : public Batsman, public Bowler
{
public:
Allrounder(std::string playerName) :Batsman(playerName), Bowler(playerName) { cout << "Allrounder info added"; }
~Allrounder() { cout << "Allrounder Destructed\n"; }
};
int main()
{
Player *ptr = new Batsman("Sachin Tendulkar");
ptr->printPlayerName();
delete ptr;
cout << endl;
Player *ptr1 = new Bowler("Anil Kumble");
ptr1->printPlayerName();
delete ptr1;
cout << endl;
Player * ptr2 = new Allrounder("Ravindra Jadeja");
ptr2->printPlayerName();
delete ptr2;
cout << endl;
}
我确保调用超类构造函数,但在多重继承的情况下,这似乎不起作用。
当前 ptr2->printPlayerName()
无法打印 Allrounder
的名称。
