#include <cstdlib>
#include <iostream>
#include <string>
#include <sstream>

using namespace std;
struct book
        {
		string title;
		int price;
	};

int main()
{
        string answer;
	book *bigbook;
	bigbook = new book[1];
	
	bigbook[0].title="harry potter";
	bigbook[0].price= 300000;
	
	cout<<endl<<"book no 0 is : "<<bigbook[0].title;
	cout<<endl<<"do you want to add a new book ? (y/n)";
	cin>>answer;
	if(answer=="y")
	{
		//increase the bigbook array but dont loose en existing data
		//its mean how to create bigbook[1] without loosing bigbook[0]
	}
	else
	{
		cout<<endl<<"see you later";
	}
	cout<<endl<<endl;
	system("PAUSE");
	return 0;
}

in this case, bigbook will grows to unexpected number of element, my froblem is how to add new book without loosing existing data in previous element. thanks for help

Same answer as your other post. Use a vector instead of an array. Vectors can grow and shrink.
