Question

Write a program in C++ using the following 2 Files: Book.h and Source.cpp

1.)   In Book.h, declare a struct Book with the following variables:

- isbn:   string

- title:    string

- price: float

2.)   In main (Source.cpp), declare a Book object named: book

- Use an initialization list to initialize the object with these values:

          isbn à 13-12345-01

          title à   “Great Gatsby”

          price à 14.50

3.)   Pass the Book object to a function named: showBook

- The function display the book.

          (Note:   Objects should almost always be passed by reference)

-   The function does not return a value.

     /* OUTPUT

     Here is the book:

     ISBN: 13-12345-01

     Title:   Great Gatsby

     Price: $14.50

*/

Answer 1

Code:

Book.h

#ifndef BOOK_H
#define BOOK_H

#include <string> // use to declare string

// struct book
struct Book
{
   std::string isbn;
   std::string title;
   float price;
};

#endif

Source.cpp

#include <iostream>
#include <iomanip>
#include <string>

#include "Book.h"

using namespace std;

// function to show book details
void showBook(struct Book *book)
{
   cout << "Here is the book:" << endl;
   cout << "ISBN: " << book->isbn << endl;
   cout << "Title: " << book->title << endl;
   // price is declared upto two decimal places
   cout << "Price: $" << setprecision(2) << fixed << book->price << endl;
}

int main()
{
   // book object declared using initilizaiton list
   struct Book myBook = {"13-12345-01", "Great Gatsby", 14.50};

   // passing above book object by reference to print it's details
   showBook(&myBook);

   return 0;
}

OUTPUT:
