Put all the files below into a folder called "ass 1", create a zip file of the folder and submit it. Do not submit executables or other files from IDE. See https://github.com/pisanorg/w/wiki (https://github.com/pisanorg/wiwiki). "Creating a zip file if you need to library.h - the prototypes of Library class functions (must support at least the functions shown in main above) • library.cpp - the implementation of Library class functions main.cpp - tests demonstrating the Library constructor and functions .main.cpp - functions to test library • Output txt - Shows the output from compiling and running your program on CSS Linux Labs. Can be generated using simplecompile.sh • README.md - modified to include any specific compiling and running instructions • simplecompile.sh - should not need to be modified Important: All the file names are in lowercase which may not be the default for your IDE, Configure your IDE to create lowercase files for classes. Tips & Hints • You can set the maximum number of books in the library to be 100 and use that to set the size of your array. Use a private variable in the library class rather rather than hard coding the number 100 into your code, such as static const int MAX - 100; lapas ww.educes 1331914 mets09956h ASP ww.edus calendar 23view 12

library.h

#ifndef LIBRARY_H
#define LIBRARY_H

#include<iostream>
using namespace std;

//Library class
class Library
{
   public:
       //public members
       Library();
       static const int MAX = 100;
       int findBook(const string& name) const;
       void addBook(const string& name);
       void removeBook(const string& name);
       void listOfBooks();

   private:
       //private members
       int numberOfBooks;
       string books[MAX];  

};

#endif

library.cpp

#include<iostream>
#include "library.h"

using namespace std;

//constructor
Library::Library()
{
   numberOfBooks=0;
}

// find a book
int Library::findBook(const string& name) const
{
   for(int i=0; i<numberOfBooks; i++)
   {
       if(books[i]==name) return i;
   }
   return -1;
}

// add a book
void Library::addBook(const string& name)
{
   if(numberOfBooks<MAX)
   {
       books[numberOfBooks] = name;
       numberOfBooks++;
   }
   else
   {
       cout<<"Failed to add a book"<<endl;
   }
}

//remove a book
void Library::removeBook(const string& name)
{
   int i = findBook(name);
   if(i==-1)
       cout<<"Book not found"<<endl;
   else{
       books[i] = books[numberOfBooks-1];
       numberOfBooks--;
   }
}

// list of books
void Library::listOfBooks()
{
   for(int i=0; i<numberOfBooks; i++)
       cout<<books[i]<<" ";
}

main.cpp

#include <iostream>
#include "library.h"

using namespace std;

//main function
int main()
{
   Library ob;
  
   //add books
   ob.addBook("A");
   ob.addBook("B");
   ob.addBook("C");
   ob.addBook("D");
  
   //list of books
   cout<<"\nlist of books before remove a book:"<<endl;
   ob.listOfBooks();
  
   //remove a book
   ob.removeBook("B");
  
   //list of books
   cout<<"\nlist of books after remove a book:"<<endl;
   ob.listOfBooks();
  
   return 0;
}

Output:

list of books before remove a book:
A B C D
list of books after remove a book:
A D C
