Problem Description

You need to handle a list of books, each with a name and a year of publication. The goal is to sort these books by their year of publication in descending order and then print the book at position 5 (index 4) after sorting.

Solution Approach

1. Read Input:

   • Read the number of books.
   • Read each book's name and year of publication.

2. Sort Books:

   • Sort the books by their year of publication in descending order.

3. Output Results:

   • Print the sorted list of books.
   • Print the book at position 5 after sorting.

Explanation

1. Data Structure:

   • struct avi holds the book name and publication year.

2. Input Reading:

   • scanf("%d", &k); reads the number of books.
   • scanf("%s%d", s1[i].c, &s1[i].a); reads each book's name and publication year.

3. Sorting:

   • The nested for loops sort the books in descending order based on the year of publication.
   • strcpy is used to swap both the book names and publication years.

4. Output Sorted List:

   • The sorted list is printed with each book's name and year.

5. Print Book at Position 5:

• If there are at least 5 books, the book at position 5 (index 4) is printed.
