Display the book with the longest title among the books whose bookType contain a specific substring. Ask the user for a substring. This function is used to demonstrate garbage collection. bookType With SpecificString(): • This function displays a book with the longest title among the books whose bookType contain a specific substring. • You should find the book as follows: 1. By traversing all books, you should find the books whose bookType include a specific substring. 2. After step 1, you should find the book whose title is the longest. You may use 'titleLength' and 'index' variable. 3. After step 2, copy the details of the book to 'bookWithLengthyTitle' object created using 'new' and display the book's details using 'bookWith LengthyTitle' object. 'new // // This function displays an book with the longest name among the books whose bookType contain a specific substring. // You should find the book as follows: 1/ 1.

After step 2, copy the details of the book to 'bookWithLengthyTitle' object created using 11 and display the book's details using 'bookWithLengthyTitle' object. // NOTE: You necessarily have to use the 'bookWithLengthyTitle' object to store the book details in it and delete it after displaying. You should not display book details using 'bll' object. // 4. Finally delete the 'bookWithLengthyTitle' object. void () { string subString: // Ask the user for a character Book* bookWithLengthy Title = new Book; int titleLength = 0; int index = -1; // enter code here } 4.
