小白成长之路（7）--C++多层派生类继承实例（期中考试）

没有一点点防备，专业老师来了一次突击期中考试，题目倒是不难，可做的时候总是有点紧张，以至于刚写完红线不少，不过还好，完美通关，特在此贴上代码，请各位大神帮助指出不足之处，给小白指点指点，再次感谢（小白代码，可笑之处轻喷）。

题目：

定义一个父类Vehicle，包含一个私有变量name，一个函数run（）；

定义两个子类Car，Plane，各包含一个私有变量move（运行方式）；

输出结果：Car is running through the wheel.

Plane is running through the wings.

(1).首先定义类文件和头文件



(2).Vehicle头文件代码

#pragma once
#include <iostream>
#include <string>
using namespace std;

class Vehicle {
private:
string name;

public:

Vehicle(string name);//含参数构造函数
~Vehicle();
public:
void set_name(string name);
string get_name();
public:

virtual void run();

};

(3).Vehicle类文件代码

#pragma once
#include "Vehicle.h"

Vehicle::Vehicle(string name) {//含参数构造函数
this->name = name;

}

Vehicle::~Vehicle() {

}

void Vehicle::set_name(string name) {
this->name = name;
}
string Vehicle::get_name() {
return name;
}

void Vehicle::run() {
cout << name << " " << "is running" << " " ;
}

(4).Car头文件代码

#pragma once
#include "Vehicle.h"

class Car : public Vehicle {

private:

string move;

public:

Car(string name, string move);
~Car();

public:

void set_move(string move);
string get_move();

public:
void run();

};

(5).Car类文件代码

#include "Car.h"

Car::Car(string name, string move) :Vehicle(name) {

this->move = move;

}
Car::~Car() {//析构函数

}

void
a43f
Car::set_move(string move) {
this->move = move;
}
string Car::get_move() {
return move;
}
void Car::run() {

Vehicle::run();
cout << " " << "through" << " " << move << endl;

}

(6).Plane头文件代码

#pragma once
#include "Vehicle.h"

class Plane : public Vehicle {

private:

string move;

public:

Plane(string name, string move);
~Plane();

public:

void set_move(string move);
string get_move();

public:
void run();

};

(7).Plane类文件代码

#include "Plane.h"

Plane::Plane(string name, string move) :Vehicle(name) {
this->move = move;

}
Plane::~Plane() {//析构函数

}

void Plane::set_move(string move) {
this->move = move;
}
string Plane::get_move() {
return move;
}
void Plane::run() {

Vehicle::run();
cout << " " << "through" << " " << move << endl;

}

(8).main文件代码

#pragma once
#include "Vehicle.h"
#include "Car.h"
#include "Plane.h"
#include <iostream>
using namespace std;

void show_vechiel(Vehicle* v) {
v->run();
}

int main() {

Vehicle* d = new Car("Car","the wheel.");
show_vechiel(d);
delete d;

Vehicle* p = new Plane("Plane", "the wings.");
show_vechiel(p);
delete p;

cin.get();
}

运行结果：



如有不足之处请各位大神不吝赐教，谢谢！
