This line here is a bit of a problem.

You havent declared the struct you are using in the function definition.
Move the declaration down after the struct declarations.

You might want to turn on gcc's very good error checking and
use something like:

cc -ansi -pedantic -Wall -o assig5 assig5.c

gcc would have told you pretty accurately, what was wrong in your code
with these added options.
