In the game of fifteen, I couldn't figure out a way to view the under-score sign "_" , I tried these lines of code: if (board[i][j] == 0) //checking if value is 0 to print a blank tile.

               printf(" _ ");

but still, 0 appears! any help would be appreciated???

It depends on where that code is. It should work IF it is inside the i,j loops AND program has not already printed 0. Does the prompt show the _, like this _ Tile to move:? That would indicate the right code is in the wrong place.

  • yes, it's inside the i,j loop.. and no, it doesn't show it. this is the loop: for (i=0; i<d;i++){ for (j=0; j<d;j++){ if (board[i][j] == 0) printf(" _ "); else printf("%d\t",board[i][j]); } printf("\n"); }

  • All things being equal, that code will print _ when board[i][j] is 0; something else is going on. You'd need to post the code for further analysis.
