I recommend:

One: get in the habit of running gcc in a conforming mode -

    gcc -x c -std=c99 -pedantic-errors <whatever>.c

Two: get a copy of the C standard (or a close approximation thereto)

    wget http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf

(This link is for a corrected draft of C99.  It isn't the latest
version of C but for starters it is an excellent reference.)

Three: read section 6.3.2.1 paragraphs 1, 3, and 4.

Four: read section 6.5.3.2

Five: after reading the above and looking again at your code,
if you are still confused ask another question here.

Six: in general, if there is ever a question or confusion you
have about C, first try to find the answer yourself in the
document whose link is given above.  If you feel you still
need help then ask in the newsgroup here.
