I have a C struct that I would like to store a const short int in. However, I get an error when I create an object saying I have uninitialized constant members. Is there a way I can initilize this value ahead of time or at least in the same line that I create the item in? I would love to just make it a short int but what I am storing is, in fact, a const short int (and it seems more than a little silly to me that my compiler is unable to convert between a short int and a const short int). Thank you When you find yourself in the company of a halfling and an ill-tempered Dragon, remember, you do not have to outrun the Dragon...

int main()
{
  struct foo
  {
    const int i;
  };

  struct foo f = { 25 };

  printf("%d\n", f.i);

  return 0;
}

Works for me.

struct foo
{
    foo (int const i) : m_i(i) {}
    int const m_i;
};

foo f (7);

Should work, too

EDIT: Tried it and it DOES work.

The OP said "C struct".

I''ll bet the OP wanted a "C solution".

Correct me if I''m wrong, but isn''t the const identifier a C++ token? If the compiler doesn''t mind the const, then nonpop''s solution is perfectly valid.
