#include<iostream.h>

#include<conio.h>

class student

{

int id;

char name[20];

public:

void get();            //here get() is inline member function as it is define in student class

                              {

               cout<<”Enter the Student Info = ”;

cin>>id>>name;

}

               void put();            //here put() is inline member function as it is define in student class

                              {

                              cout<<”Student Info = ”;

                              cout<<id<<name;

}

};

void main()

{

clrscr();

student st;

               st.get();

               st.put();

               getch();

}
