Why is it compile time error ?

Because display is called without any object.

No. Only static functions can access static members.
Deepak Kumar said:

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.

Non static method can't access static member!

The class Indiabix don't have an object for call a member function dispaly().

Statics members are accessed by static functions.

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

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

Can not call display() function without object! Because display() is not declared static.
