This is in my txt file that i'm trying to put into a 2d array:

Sometimes the user will have more or less rows/columns of data so I got this to dynamically build the 2d array, just dont know how to get the info into it...here:

level_map = new int *[LEVEL_MAP_ROWS];
for(int i = 0; i < LEVEL_MAP_ROWS; i++)
{
    level_map[i] = new int [LEVEL_MAP_COLUMNS];
}

I'm accessing the txt file like this:

ifstream file ("theFile.txt");

`std::vector> level_map(height, std::vector(width));` access as `level_map[y][x]` – Neil Kirk Mar 26 '15 at 13:22

yeah but how to get the width and height of the block of 1's and 0's in the txt file? – doomglhfcn Mar 26 '15 at 13:30
Grab a line and count the number of characters? – Neil Kirk Mar 26 '15 at 13:33
