Extend your previous program to provide additional functionality as follows:

Step (1)

Modify your program to use an array of structs, which will replace the parallel arrays, like this:

// These declarations should be at file scope.

struct Book {
string title;
string author;
};

const int ARRAY_SIZE = 1000;
Book books [ARRAY_SIZE];

Modify the remainder of the program to work with the new array of structs, but maintaining exactly the same functionality.

Step (2)

Add a new function to sort the array by title. The signature should be as follows:

void sortByTitle (int count)

Add a second function to sort the array by author. The signature should be as follows:

void sortByAuthor (int count)

Using these new functions, modify your code for Show All and Search Title to display the output sorted alphabetically by title. Modify Search Author so that it displays the output in alphabetical order of author.
