C++虚函数接口类

/*======================================================================接口类：仅含有纯虚函数的类称为接口类。无数据成员成员函数全部是纯虚函数接口类更多的表达一种能力或协议起飞降落子类一定要实现这些纯虚函数/*======================================================================*/#include <iostream>#include<string>using namespace std;class Flyable{public:Flyable() {}virtual ~Flyable(){}virtual void land() = 0;virtual void takeoff() = 0;};class Plane:public Flyable{public:Plane(string name) {this->m_strNum = name;}~Plane() {}virtual void takeoff() {cout << "飞机起飞" << endl;}virtual void land(){cout << "飞机降落" << endl;}virtual void printcode(){cout << "我是飞机"<< m_strNum << endl;}protected:string m_strNum;};class FightPlane:public Plane{public:FightPlane(string name):Plane(name){}virtual ~FightPlane(){}virtual void takeoff(){cout << "战斗机起飞" << endl;}virtual void land(){cout << "战斗机降落" << endl;}virtual void printcode(){cout << "我是战斗机" << m_strNum << endl;}private:};void flyMatch(Flyable *f1, Flyable*f2){f1->takeoff();f1->land();f2->takeoff();f2->land();}int main(){Flyable *f1=new FightPlane("f1");FightPlane *f2 = new FightPlane("f2");flyMatch(f1, f2);return 0;}
