Thread: bunch of warnings

hello guys, how are you,
I got a small problem with my code, and I would love if somebody can walk me through it step by step and help me debug the code
here is my code

Code:

#include <stdio.h>
#include <string.h>
 struct books printhello();
 int outputboo( struct books boo);
struct Books{
   char  title[50];
   char  author[50];
   char  subject[100];
   int   book_id;
};



main( ){



}

outputboo(struct books boo){
    printf(" here is your value of the function of the STRUCT :%i",&boo.book_id );
}

struct books printhello(){
      struct books boo ;

      scanf("%i",&boo.book_id);
      printf("your boo book_id is : %i", boo.book_id);
      return Boo;
}

and here is the code in Code::Blocks



and here is the warning I got :

The first thing you need to do is move your function prototypes to after the structure definition. And remember C is case sensitive.

Next main() should be defined to return an int, and you should return a value from this function.

Jim

I moved the prototypes after the structure definition and still getting the error (13|warning: parameter has incomplete type)
and I changed main to :

Code:

int main( ){

return 0;

}

and still the same problem

C and C++ are case sensitive.
