Hi guys, first the problem. I''m working on a way to read a map file that simply stores the height of each space on the board. I read the first two numbers which are the width and height of the board in spaces, use these numbers to create a 2D array. Then I want to read the rest of the numbers into this array I just created. here is the code thus far.

#include <fstream.h>
#include <iostream>

using namespace std;

main()
{
int** map;
int row, column;
int hexheight;
char c;

fstream FILE;

FILE.open("hexboard.txt", ios::in);

FILE >> column >> row;

cout << column << endl << row << endl;

map = new int* [column];

  for(int i=0; i>column; i++)
  {
   map[i] = new int [row];
  }

cout << "array created..." << endl;

  for(int x = 0; x < row; x++)
  {
      for(int y = 0; y < column; y++)
      {
       FILE >> hexheight;
       cout << hexheight;
       map[x][y] = hexheight;
      }
   cout << endl;
  }
  
FILE.close();

cin >> c;

}

the stuff i''m using in the text file is as follows, and it''s named hexboard.txt

5
6
3 1 1 1 1
1 1 2 2 1
1 1 2 3 2
1 1 2 2 1
1 1 2 1 1
1 1 1 1 1

as it''s printing out the heights, it gets as far as the 3rd row, second column in before it just kinda freezes. Things I suspect are the way I created the 2D map array, and maybe the way fstream works. If you could get me pointed in the right direction I''d be most grateful! Thanks! Nel

There are a few problems with this.

1) Don''t mix old style iostream headers with new style iostream headers. i.e. change fstream.h to just fstream.

2) You access your map array by [row][column], but you create it [column][row] in the nested for loop.

3) When you dynamically create your map array you use "i > column" This should probably be a < (and probably change column to row (see above) ).

4) You never free the memory allocated for the map array.
