题目如下

代码如下

.h

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

class Toy
{
public:
	Toy();
	Toy(string name,int price,string place);
	~Toy();

	string getName() const;
	int getPrice() const;
	string getPlace() const;

	void changePrice(float count);
	void discription();
private:
	string name;
	int price;
	string place;
	float count = 1.0;
};

.cpp

#include "Toy.h"
#include <string>
#include <iostream>

using namespace std;

Toy::Toy()
{
}

Toy::Toy(string name, int price, string place)
{
	this->name = name;
	this->price = price;
	this->place = place;
}

Toy::~Toy()
{
}

string Toy::getName() const
{
	return name;
}

int Toy::getPrice() const
{
	return price;
}

string Toy::getPlace() const
{
	return place;
}

void Toy::changePrice(float count)
{

	this->price = price*count;
}

void Toy::discription()
{
	cout << this->name << ":" << this->price << "," << this->place << endl;
}

 main.cpp

#include "Toy.h"

int main() {
	Toy toy("变形金刚", 5600, "China");
	toy.discription();
	toy.changePrice(0.5);
	toy.discription();

	system("pause");
	return 0;
}
