When I include i++; inside this loop I get a runtime error and I have no idea why I get it:
Do you have any idea?

C++ Syntax (Toggle Plain Text) 
  1.  while (i <= 3){
  2.  
  3.            if (tauler[PacMan.y][PacMan.x]==0)
  4.                xoc = 0;
  5.            else if (tauler[PacMan.y][PacMan.x]==1)
  6.                xoc = 1;
  7.            else if (tauler[PacMan.y][PacMan.x]==2)
  8.                xoc = 2;
  9.            else 
  10.                xoc = 3;
  11.  
  12.  
  13.          i++;
  14.          PacMan.x += dx;
  15.          PacMan.y += dy;
  16. }

I can't crank an engine. Look at my car mark, please: it's a Crow Victoria.
Do you have any idea?

What was the value of i before you went into the while loop?
