CAN SOMEONE FIX THE ERROR?

THIS IS MY CODE: (THE STRUCT IS ON POKEMON.H ALSO PLEASE FIX IT SO IT WORKS ON ISO C90, I'M NOT ALLOWED TO CONVERT TO C99)

pokemon.h (struct file)

struct pokemon { int level; char name[25]; };

iofunctions.h

int readfile( struct pokemon pokearray[ ], int* num, char filename[ ] ); int writefile( struct pokemon pokearray[ ], int num, char filename[ ] );

iofunctions.c

#include

#include "iofunctions.h"

#include "pokemon.h"

int max_size;
