help my coding is nearly finish it just i don't know to make the getCount() function to return the number of book objects that have been created..
and dont understand this line>>the count data member should be initialized to zero and must keep track of number of book objects..
my coding is like this

Code:

class Book
{
private:

string author,title;
const short bookType;
int count;

public:
Book( const string& author,const string& title, int bookType = 1):count(0);
~Book();
string getTitle();
string getAuthor();
Void setTitle(string title);
void setAuthor(string author);
int getCount(){return count;};

}

	
Book::Book( const string& author,const string& title, int bookType = 1);
	{    
setAuthor(author);
              setTitle(title);
		++count; 
}

Book::~Book~(){
    --count;
    
}

int Book::count = 0;


void Book::setTitle(string title)

{
title = title
}

string Book::getTitle() 

{

return title;

}
void Book::setAuthor(string author)

{
author = author;
}

string Book::getAuthor() 

{

return author;

}

Hey dude what you can do you can have a static counter in the class

and just increment that in constructor

you can look at this code snippet for your help

Code:

#include <iostream>

class Test {
  static int counter;
public:
  Test() {++counter; }
  void show() { std::cout << "counter == " << counter << std::endl; }
};

int Test::counter = 0;

int main() {
  Test t1, t2, t3, t4, t5, t6, t7, t8 ,t9;
  t1.show();
  return 0;
}

Don't forget to implement or disable a copy constructor, so that the count goes up when you copy a book.
