定义一个学生类和一个老师类。学生类有学号、姓名、两门或多门成绩数据，老师有职工号和姓名数据。学生对象能查看自己成绩信息，教师能对学生成绩进行录入。编程实现初始化一个或多个学生信息，初始化一个老师信息。实现学生成绩的输入和相关学生的成绩查看功能。

#include<iostream>#include<string>using namespace std;class student;class teacher{public:teacher(int t_n, string t_na){t_no=t_n;t_name=t_na;}void change (student& );void t_show(){cout<<"老师的职工号:"<<t_no<<" "<<"老师的姓名:"<<t_name<<endl;}private:int t_no;string t_name;};class student{public:student(int s_n, string s_na,float eng,float mat){s_no=s_n;s_name=s_na;english=eng;maths=mat;}friend void teacher::change(student& );void s_show(){cout<<"学号:"<<s_no<<" "<<"姓名:"<<s_name<<" "<<"英语成绩:"<<english<<" "<<"数学成绩:"<<maths<<endl;}private:int s_no;string s_name;float english;float maths;}; void teacher::change(student& d) { cout<<"请输入"<<d.s_name<<"的英语成绩"; cin>>d.english; cout<<"请输入"<<d.s_name<<"的数学成绩"; cin>>d.maths; } int main() { teacher teacher1(01,"陈一"); student student1(1,"陈二",0,0); student student2(2,"陈三",0,0); teacher1.t_show(); teacher1.change(student1); teacher1.change(student2); student1.s_show(); student2.s_show(); return 0; }
