Thread: How to define semantics of object access when no member is specified?

Is there a way to define how to access an object(struct/union) when no member is specified? For example, could I define a struct ...

Code:

struct{
     int a;
     int b;
}c;

... and define that c should be accessed as an int when no member is specified, effectively making the a 3 int struct? The difference between this and anonymous objects is that I want a and b to still be accessed as members, like c.a and c.b.

No, I CAN'T use C++.

No.

The struct is a defined object with specified contents and a known size.

If you try to access it as anything but a struct, you will either a) garbage the contents, b) cause a run time error or c) get told your code can't be compiled...

If you need a third int, add it to the struct or define another variable.
