Can the address of a variable with automatic storage duration be taken in its definition?

Question

Is it allowed to take the address of an object on the right hand-side of its definition, as happens in foo() below:

typedef struct { char x[100]         


        

Answer 1

The question has already been answered, but for reference, it doesn't make much sense. This is how you would write the code:

typedef struct { char x[100]; } chars;

chars make (void) {
  chars c;
  /* init c */
  return c;
}

void foo(void) {
  chars b = make();
}

Or perhaps preferably in case of an ADT or similar, return a pointer to a malloc:ed object. Passing structs by value is usually not a good idea.
