main.cpp

#include"Stud.h"#include"Stud.cpp"using namespace std;int main(){    Stud s1,s2(1101,"xiaoming",20,'m',99.8);    s1.set_age(21);    s1.display();    s2.display();    return 0;}

Stud.h

#ifndef _STUD_H#define _STUD_H#include<iostream>using namespace std;class Stud{        int id;        string name;        int age;        char sex;        float grade;        public:            Stud();            Stud(int i,string na,int ag,char se,float gr);            void set_age(int a);            void display();};#endif

Stud.cpp

#include"Stud.h"using namespace std;Stud::Stud(){        id=0;        name='0';        age=0;        sex='f';        grade=0;}Stud::Stud(int i,string na,int ag,char se,float gr){        id=i;        name=na;        age=ag;        sex=se;        grade=gr;}void Stud::set_age(int a){        age=a;}void Stud::display(){        cout<<"ID:"<<id<<endl<<"Name:"<<name<<endl<<"Age:"<<age<<endl<<"Sex:"<<sex<<endl<<"Grade:"<<grade<<endl<<endl;}

运行结果
