根据给定的汽车类vehicle(包含的数据成员有车轮个数wheels和车重weight)声明,完成其中成员函数的定义,之后再定义其派生类并完成测试。
小车类car是它的派生类,其中包含载人数passenger_load。每个类都有相关数据的输出方法。
输出样例:
在这里给出相应的输出。例如:
Type:Vehicle
Wheel:4
Weight:1000kg
Type:Car
Type:Vehicle
Wheel:4
Weight:2000kg
Load:5 persons
它的派生类,其中包含载人数passenger_load。每个类都有相关数据的输出方法。
代码实现:
#include<iostream>
using namespace std;
class Vehicle
{ protected: int wheels; float weight; public: Vehicle(int wheels,float weight); int get_wheels(); float get_weight(); float wheel_load(); void show();
}; /* 请在这里填写答案 */
class Car : public Vehicle{private:int passenger_load;public:Car(int a,float b,int c):Vehicle(a,b){passenger_load=c;}void show(){cout<<"Type:Car"<<endl;Vehicle::show();cout<<"Load:"<<passenger_load<<" persons"<<endl;}};Vehicle::Vehicle(int wheels,float weight):wheels(wheels),weight(weight){
}
void Vehicle::show(){cout<<"Type:Vehicle"<<endl;cout<<"Wheel:"<<wheels<<endl;cout<<"Weight:"<<weight<<"kg"<<endl;
}int main ()
{ Vehicle v(4,1000);v.show(); Car car1(4,2000,5); car1.show (); return 0;
}
