C++ dynamic structures

Hi,

Im new to C++ and trying to self teach myself whilst I sit at my
unentertaining day job (thought i'd put that across before im accused
of cheating on my homework, im 45...)


Anyway I'm trying to dynamically assign a structure whilst I read from
a file, however my program crashes, and im not sure why other than that

its to do with my memory operations using new and delete.


Im pretty good at C so the reason for learning is so that I can truely
put C/C++ on my CV instead of just C... but also im interested in the
object orrientated aspect.


Could I use a class instead of a structure? whats best? where am I
going wrong?


Thanks


Heres my Code -


#include <iostream>
#include <fstream>
#include <string>


using namespace std;


struct TOKEN
{
string linetoken;



};


int main()
{

TOKEN *Tokens;


int counter = 0;
ifstream ifs("data.txt");
string line;


while(getline(ifs,line))
{


Tokens = new TOKEN[counter + 1];


Tokens[counter].linetoken = line;


//cout << "[ " << line << " ]" << endl;
cout << Tokens[counter].linetoken << endl;
counter = counter + 1;
}


cout << "AAAAAAAA";


delete Tokens;
return 0;
}

.
