一代码
#include<iostream>
#include<string>
using namespace std;
class Stu
{
private:
string name; //学生姓名
int chinese; //语文成绩
int math; //数学成绩
int num;
public:
void setStudent(string n,int ch,int ma);
void show();
void setName(string n);
string getName();
float average();
};
void Stu::setStudent(string n,int ch,int ma)
{
name=n;
chinese=ch;
math=ma;
}
void Stu::show()
{
cout<<"Name:"<<name<<endl;
cout<<"Score"<<chinese<<" "<<math<<endl;
cout<<"average:"<<(math+chinese)/2<<" "<<"num:"<<math+chinese<<endl;
}
float Stu::average()
{
return (math+chinese)/2;
}
void Stu::setName(string n)
{
name=n;
}
string Stu::getName()
{
return name;
}
int main()
{
Stu s1,s2;
s1.setStudent("Lin daiyu", 98, 96); //对象置初值
s2.setStudent("Jia baoyu", 90, 88); //对象置初值
s1.show();//打印信息
s2.show();//打印信息
s1.setName("xue baochai");//重新置p1对象的名字
s1.show();
cout<<"s1.Name: "<<s1.getName()<<endl;//打印对象的名字
cout<<"s1.average: "<<s1.average()<<endl;//打印对象的成绩
return 0;
}
二运行结果
三 心得
慢慢体会到了类与对象的概念
四 知识点
类与对象
