# problem with move function in game of fifteen

I am having problem with my move function in the game of fifteen. I don't know what do. I need someone to point out what I'm doing wrong. Thanks in anticipation.

//To create rows (i) and columns (j) for board. int blank = 0;

``````for (i = 0; i < d -1; i++)
{
for (j = 0; j < d -1; j++)
{

//To make sure the values of i and j are within allowed values.
if ((i < 0 || i > d - 1) || (j < 0 || j > d - 1))
{

//checks for leftward moves and moves if possible

if ((board[d-1][d-1] = blank) && (board[i][j] = tile))
{

if (board[i][j+1] == blank)
{
Swap (&board[i][j-1], &blank);
}
if (board[i][j-1] == blank)
{
Swap (&board[i][j-1], &blank);
}
//checks for rightward moves and moves if possible
if (board[i+1][j] == blank)
{
Swap (&board[i+1][j], &blank);
}
if (board[i-1][j] == blank)
{
Swap (&board[i-1][j], &blank);
}
}
return true;
}
}
}
return false;
``````

}

I defined a swap function appropriately with the prototype placed accordingly in the right place.

Outermost condition `((i < 0 || i > d - 1) || (j < 0 || j > d - 1))` is never true in the loops. Looks like you should revise all your conditions.
