#include<iostream.h>
#include<conio.h>
#include<string.h>
class A
{
int rno;
char name[10];
public:
void get()
{
cout <<"enter your name" << endl;
cin >>name;
cout <<"enter your rollno"<< endl;
cin >>rno;
}
void show();
};
void A ::show()
{
cout << name << "\t" << rno;
}
void main()
{
A a1;
clrscr();
a1.get();
a1.show();
getch();
}
