Im so close to finish fifteen. I have a mistake about syntax with the last } for my function Move() and Won(). Here the error message when I compile : fifteen.c:279:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]
}
^
fifteen.c:300:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]
}

2 errors generated.
make: *** [fifteen] Error 1. I red that it could be that it didn't see the end of the loop, because using else, I didn't listed all the possibilities ending. so as it proposed, i erase else, before false. But still the same error. Here are the code for my two function. Tks : `/**
* If tile borders empty space, moves tile and returns true, else
* returns false.
*/
bool move(int tile)
//int tile is number choosen to move by the player
{
int i = 0; // row
int j = 0; // column
int blank = 0; // blank's position
// find the location of the number choosen by player
for (i = 0; i < d; i++)
{
for (j = 0; j < d; j++)
{
//find blank's tile location
if (board[i][j] == 0)
{
blank = board[i][j];
}
if (board[i][j] == tile)
{
//check if tile's location is a legal move from the blank's tile
if (i > 0)
{
if (board[i - 1][j] == blank) // if blank is above tile

board[i - 1][j] = tile;
board[i][j] = blank;
