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:
cpp
#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;
}
