fifteen initialize not working correctly

Question

so the line of code below gives me the output of:

• 2|3|-4
• -3|-2|-1
• 8|-7|95

Can anyone see what I ve done wrong? Thank you.

void init(void)
{
    for (int i = 0; i < d; i++)
    {
        for (int j = 0; j < d; j++)
        {
            board[i][j] = d^2 - i*d - j - 1; 
            if (i + 1 == d && j + 1 == d)
                board[i][j] = 95; 
        }
    }
    if ((d^2 - 1) % 2 != 0)
    {
        int temp = board[d-1][d-2];
        board[d-1][d-2] = board[d-1][d-3];
        board[d-1][d-3] = temp;
    }
}

The ^ operator is not an exponent operator as it is in traditional mathematics. It is the BITWISE XOR operator. You weren't actually squaring d. There is no exponent operator. The closest thing to this is the pow(a,b) function ( #include ) that returns a to the power of b.
