Programming the game of life..Some help needed.

[CapMaster]

I'm having some trouble programming the game of life. In the version my teacher gave us, it involves a class with a private grid variable for the game. Here's the class she gave us:

..
const int maxrow = 20, maxcol = 60;    //  grid dimensions
class Life {
public:
    Life ();
    void initialize();
    void print();
    void update();
private:
// allows for two extra rows and columns
    int grid[maxrow + 2][maxcol + 2];  
    int neighbor_count(int row, int col);
..

Now for the initializiation , she wants some #s or *s in pre-determined places that are to be read in from a data file, like this:
8 6
8 9
9 7
19 5

And for everything else, a blank space. Here's what I have, including a constructor to try to make the blank spaces:

..
Life::Life()
{
    int x, y;
    for (x=0; x<maxrow; x++)
    {
        for (y=0; y<maxcol; y++)
        {
            grid[x][y]=' ';
        }
    }
}
void Life::initialize()
{
    ifstream infile;
    infile.open("lifedata.txt");
    int x, y;
    while (!infile.eof)
    {
        infile>>x>>y;
        grid[x][y]='#';
    }
..

Here's my problem though. It says that I can't use !infile.eof in a class function. I have it there because what I'm trying to do is as long as there's numbers in the file, set those coordinates in the grid to be a # sign. Everything else, bet set to a blank space. I also have a question concerning filling arrays with classes, functions, and large programs like this. After I fill it in with the x and y, I want it to be like that everywhere in the program, that in every class function grid[x][y] retains the same values. How can I get the compiler to do those two things?

ios::eof() is a function, try

    while (!infile.eof)
 

[CapMaster]

What do you mean by that? Where should I put it?

forgot to put the correct code

while (!infile.eof())

Also, your 2D array holding the values is declared as an integer array- but you're giving it character values such as ' ' and '#'. Should grid be a char array?
