程序设计与算法（三）C++面向对象程序设计第五周相关笔记

一、

继承与派生的基本概念

#include<bits/stdc++.h>
using namespace std;
class Student{
    private:
        string name;
        char sex;
        int height,weight;
    public:
        Student(string _name,char _sex,int _h,int _w):name(_name),sex(_sex),height(_h),weight(_w){    
        }
        void get_info(){
            cout<<name<<'\n'<<sex<<'\n'<<height<<" "<<weight<<endl;
        }
        void set_h(int h){
            height = h;
        }
        void set_w(int w){
            weight = w;
        }
};

        int grades;
    public:

        }
        void get_info(){
            Student::get_info();
            cout<<grades<<'\n'<<is_baoyan<<'\n';    
        }
        void set_g(int g){
            grades = g;
        }
        void set_b(bool b){
            is_baoyan = b;
        }
