Question

C++ Double Question :

1ST.

The printAllBooks function from Homework 5 was very useful, let’s do it again, but with an array of Book this time! Write a new printAllBooksfunction which will be useful to display the contents of your library. This function should:

• Accept two parameters in this order:

• • array books: array of Book objects.

  • int: number of books in the array (Note: this value might be less than the capacity of 50 books)

• This function does not return anything

• If the number of books is 0 or less than , print “No books are stored”

• Otherwise, print “Here is a list of books” and then each book in a new line using the following statement

cout << books[i].getTitle() << " by ";
cout << books[i].getAuthor() << endl;

In the Answer Box below, paste your Book class (both the header and implementation), and your printAllBooks function, not the entire driver program you are using to test your printAllBooks function. As in the previous problems, do not include all the extra headers and #ifndef/#define.

2ND :

As we have seen in homework5 that some users want to know if there are books by their favorite author. Instead of printing all books, we will print the list of books that are written by the given author. So let’s write a function printBooksByAuthor that fulfills the following criteria

• Your function should be named printBooksByAuthor

• Your function should take three parameters in the following order:

  • Array of book objects: books

  • int: number of books (Note: this value might be less than the capacity of 50 books array)

  • string: author name

• You function should not return anything.

• If the number of books is 0 or less than 0, print “No books are stored”

• If there are no books by the author then you should print the following, “There are no books by <author>”

• If there are one or multiple books by the same author, you should print the following statement, “Here is a list of books by <author>” followed by, each book’s title by this author in a new line.

Note: In the test case, you can always assume that the number of books matches the number of elements in the books array.

Example: There are two books by Author A.

Function Call:	Book book1 = Book("Book 1", "Author A"); Book book2 = Book("Book 2", "Author B"); Book book3 = Book("Book 3", "Author A"); Book listOfBooks[] = {book1, book2, book3}; int numberOfBooks = 3; string author = "Author A"; printBooksByAuthor(listOfBooks, numberOfBooks, author);
Expected Output:	Here is a list of books by Author A Book 1 Book 3

In the Answer Box below, paste your Book class (both the header and implementation), and your printBooksByAuthor function, not the entire driver program you are using to test your printBooksByAuthor function. As in the previous problems, do not include all the extra headers and #ifndef/#define.

Answer 1

void printBooksByAuthor(Book [] listOfBooks, int numberOfBooks, string author) {

bool flag = false;
if(numberOfBooks == 0)
cout <<"No books are stored" <<endl;
else {

for(int i =0 ; i<numberOfBooks ; ++i) {

if(listOfBooks[i].getAuthor() == author ){
if(!flag )
cout << "Here is a list of books by "<< author<<endl;
cout << listOfBooks[i].getTitle() << endl;
flag = true;

}

}

if(!flag ) {
cout << "There are no books by " << author<<endl;

}

}

}

Thanks, PLEASE COMMENT if there is any concern.
