C: 12. Structures

Structure is another user defined data type available in C that allows to combine data items of different kinds.

Structures are used to represent a record. Suppose you want to keep track of your books in a library. You might want to track the following attributes about each book −

  1. Title
  2. Author
  3. Subject
  4. Book ID
Defining a Structure:- 
struct Books {
   char  title[50];
   char  author[50];
   char  subject[100];
   int   book_id;
} book; 

Example:- 
#include <stdio.h>
#include <string.h>
 
struct Books {
   char  title[50];
   char  author[50];
   char  subject[100];
   int   book_id;
};
 
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, "Nuha Ali"); 
   strcpy( Book1.subject, "C Programming Tutorial");
   Book1.book_id = 6495407;

   /* book 2 specification */
   strcpy( Book2.title, "Telecom Billing");
   strcpy( Book2.author, "Zara Ali");
   strcpy( Book2.subject, "Telecom Billing Tutorial");
   Book2.book_id = 6495700;
 
   /* print Book1 info */
   printf( "Book 1 title : %s\n", Book1.title);
   printf( "Book 1 author : %s\n", Book1.author);
   printf( "Book 1 subject : %s\n", Book1.subject);
   printf( "Book 1 book_id : %d\n", Book1.book_id);

   /* print Book2 info */
   printf( "Book 2 title : %s\n", Book2.title);
   printf( "Book 2 author : %s\n", Book2.author);
   printf( "Book 2 subject : %s\n", Book2.subject);
   printf( "Book 2 book_id : %d\n", Book2.book_id);

   return 0;
}

Output:- 
Book 1 title : C Programming
Book 1 author : Nuha Ali
Book 1 subject : C Programming Tutorial
Book 1 book_id : 6495407
Book 2 title : Telecom Billing
Book 2 author : Zara Ali
Book 2 subject : Telecom Billing Tutorial
Book 2 book_id : 6495700

WP: 8. Dynamically show post taxonomies and their data in tab format [Solved]

    Today I ran into a problem, I need to dynamically show post taxonomies and their data in tab format and found this solution. And nonetheless, It's better to fix the thing with some bunch of code rather than uploading one more bulky plugin on your website that will end up making your site heavy. Just follow the steps below and avoid heading up into any malicious or bulky plugin for this particular problem from now on forever. Step 1: Get the taxonomies terms first <?php     $terms = get_terms( array(       'taxonomy' => 'off_plan_categories',       'hide_empty' => true,     ) );     // echo '<pre>';     // print_r($terms);     // die; ?> Step 2:  Execute loop first for tab navigation <nav id="offPlanPropertyTabs" class="offplan-property-type-tabs nav nav-tabs"> <?php foreach($terms as $key => $term): ?>   <button class="nav-item nav-link <?php...
