Structures as Function Arguments

#include <stdio.h>
#include <string.h>

struct Books {
   char  title[50];
   char  author[50];
   char  subject[100];
   int   book_id;
};

/* function declaration */
void printBook( struct Books book );

int main( ) {

   struct Books Book1;        /* Declare Book1 of type Book */
   struct Books Book2;        /* Declare Book2 of type Book */

   /* book 1 specification */
   strcpy( Book1.title, "C Programming");
   strcpy( Book1.author, "ramratan bissoo");
   strcpy( Book1.subject, "C Programming Tutorial");
   Book1.book_id = 654123;

   /* book 2 specification */
   strcpy( Book2.title, "Miracle Billing");
   strcpy( Book2.author, "DEEPAK SHARMA");
   strcpy( Book2.subject, "Miracle Billing Tutorial");
   Book2.book_id = 420420;

   /* print Book1 info */
   printBook( Book1 );

   /* Print Book2 info */
   printBook( Book2 );

   return 0;
}

void printBook( struct Books book ) {

   printf( "Book title : %s\n", book.title);
   printf( "Book author : %s\n", book.author);
   printf( "Book subject : %s\n", book.subject);
   printf( "Book book_id : %d\n", book.book_id);
}

output:--
Book title : C Programming
Book author : ramratan bissoo
Book subject : C Programming Tutorial
Book book_id : 654123
Book title : Miracle Billing
Book author : DEEPAK SHARMA
Book subject : Miracle Billing Tutorial
Book book_id : 420420
