面向对象-单继承（公有继承）

//公有继承
#include <iostream>
#include <string>
using namespace std;

class Car{
    public:
        void get_value(){
            cin>>cost>>clour;
        }
        void display(){
            cout<<"cost:"<<cost<<endl;
            cout<<"clour:"<<clour<<endl;
        }
    private:
        int cost;
        string clour;       
}; 

//单继承（公有）
class Rice_Car : public Car{
    public:
        void get_value1(){
            cin>>name;
        }
