This pointer doesn't works in static member functions since the static member functions doesn't require an object to invoke the member function.
And display member function function is not a static member function it is normal member function so if we call display we need to create a object then it call.

Replace int main() part by following Code.
int main()
{
IndiaBix obj;
obj.SetData(33);
obj.Display();
return 0;
}
Output : 33
int main()
{
IndiaBix obj;
obj.SetData(33);
obj.Display();
return 0;
}
Output : 33

Because display is not a static function, it cannot be accessed by class name.

Non static method can't access static member!

Because Display() is non-static method and non-static methods are always called using object.
eg :-
IndiaBix obj;
obj.Display();
Correct way to call.
eg :-
IndiaBix obj;
obj.Display();
Correct way to call.

No. Only static functions can access static members.

Because display is called without any object.
