What?

The size of the array is determined by the initializer.

We were merely talking about adding "const" and "static" to the existing
declaration of "maxval", like this:

static const char *get_foo(size_t a)
{
  static const char *numbers[] =
  {
    "zero",
    "one",
    "two",
    "three",
    "four"
  };
  static const size_t maxval = sizeof numbers / sizeof numbers[0] - 1;

  return numbers[a <= maxval ? a : maxval];
}
