Accessing child variables through higher level structures

Question

If I have these structures:

typedef struct { int x; } foo;
typedef struct { foo f; } bar;

Normally you would access x through

Answer 1

In C++, it is possible in two ways. The first is to use inheritence. The second is for bar to contain a reference member named x (int &x), and constructors that initialise x to refer to f.x.

In C, it is not possible.
