Question

Talking about structs, is it possible to just copy a struct‘s fields to another struct without explicitly calling the type field name?

Let me show you an example:

struct StructA
{
   char Name[20];
   int Age;
};

struct StructB
{
   StructA FieldStructA;

   int SomeOtherDeclarations;
   // ...
};

So, I could access the StructA fields on StructB doing this:

StructB strB;
strB.FieldStructA.Name[0] = 0;

What I want to do is access the StructA fields through StructB without accessing the data field on StructB. Something like inheritance between classes. Like this:

StructB strB;
strB.Name[0] = 0;

I want to inherit StructA fields on StructB. I know that I could do that with classes, but I have to use struct for some reasons (interop, specific use of stack and so on).

Thanks for your time!

If you are using gcc, try making it an anonymous member:

http://gcc.gnu.org/onlinedocs/gcc/Unnamed-Fields.html

struct StructA
{
  char Name[20];
  int Age;
};

struct StructB
{
   struct StructA;

   int SomeOtherDeclarations;
   // ...
};
