Pset3: strange problem while testing init() function

Question

I am trying to test the basic functioning of init(), but for some reason I am finding that for certain elements in the array, I am either missing a value or a value is doubled. Please help me understand what is causing this. If I place a printf function underneath the line where 'y' is decremented, the array prints as it is supposed to. However, if I attempt to print out individual values outside of the loops, I get some incorrect values. For instance, board[0][3] prints out 11, as does board[1][0]. Everything else prints as it should.

int row, col, d = 4, y = (d*d-1), board [d-1][d-1];

for (row = 0; row < d; row++)
{
    for (col = 0; col < d; col++)
    {
        board[row][col] = y;
        y--;
    }
}

Answer 1

When you declare an array, such as board, you want to use the actual size of the array, without subtracting 1.
