using namespace std;
class student{
private:
int rollnum,age;
char name[60];
public:
void getstd(){
cout<<"Enter the Name"<<endl;

}
void showstd(){
cout<<"Name is "<<name<<endl<<"Age is "<<age<<endl<<"Roll Number is"<<rollnum<<endl;
}
};
int main()
{
student s1;
cout<<"Enter Value of Students\n";

cout<<"Output\n";
s1.showstd();
cout<<"/*\nName-Sanjampreet Singh\nRoll Number-1507967\n*/";
}
