The document defines a C++ class called waqar that contains integer, string, and float data members to store a student's roll number, name, and GPA. Methods are defined to input student data, output identifying information, and display the stored data members. The main function creates two waqar objects and calls their methods to input data for one object, output a message from another method, and display the stored data members.

1. #include<iostream>
using namespace std;
class waqar{
int r;
string n;
float g;
public:
void khan() {
cout<<"nEnter your roll numbern";
cin>>r;
cout<<"Enter your name n";
cin>>n;
cout<<"Enter your gpa n";
cin>>g;
}
waqar();
void mama();
void shah(){
cout<<"ni am shah";
}
};
waqar::waqar(){

2. cout<<"I am waqar hussainn";
cout<<"Software Engineering from Abasyn university peshawar";
};
void waqar::mama(){
cout<<"Your roll number is = "<<r<<endl;
cout<<"your Name is = "<<n<<endl;
cout<<"Your Gpa is = "<<g<<endl;
};
main()
{
waqar b,f;
f.shah();
b.khan();
b.mama();
int a;
cout<<"enter Exit to end program";
cin>>a;
