C++ I have some error messages I'm trying to clean up. There is a .h file and a .cpp file marked down below. I am getting no operator << and >> matches these operands and identifier getline is undefined. Here is my code.

BookClass.h

#include #include

using namespace std; class BookClass { string title; string author; string publisher; string isbn; double price; int year; int numInStock;

public: void storeBook(string bookTitle, string authorName, string bookPublisher, string bookISBN, double bookPrice, int bookYear, int booksInStock) { title = bookTitle; author = authorName; publisher = bookPublisher; isbn = bookISBN; price = bookPrice; year = bookYear; numInStock = booksInStock; } void displayBookInfo() { cout << "Title: " << title << endl; cout << "Author: " << author << endl; cout << "Publisher: " << publisher << endl; cout << "ISBN: " << isbn << endl; cout << "Price: " << fixed << setprecision(2) << price << endl; cout << "Year: " << year << endl; cout << "Books in Stock: " << numInStock << endl; } void checkOutBook() { if (numInStock > 0) { cout << "Checking out a book." << endl; numInStock--; } else cout << "No books in stock." << endl; } void returnBook() { cout << "Book returned successfully." << endl; numInStock++; } string getTitle() { return title; } int getNumInStock() { return numInStock; } };

Source Code

#include "BookClass.h"
