Struct Inheritance in C

Question

Can I inherit a structure in C? If yes, how?

Answer 1

I like and used the idea of Typesafe inheritance in C.

For example:

struct Animal
{
    int weight;
};

struct Felidae
{
    union {
      struct Animal animal;
    } base;
    int furLength;
};

struct Leopard
{
    union {
      struct Animal animal;
      struct Felidae felidae;
    } base;

    int dotCounter;
};

Usage:

struct Leopard leopard;
leopard.base.animal.weight = 44;
leopard.base.felidae.furLength = 2;
leopard.dotCounter = 99;
