snake game

binaary (23)
I'm working through a youtube tutorial on making a snake game and have came accross an error I can't seem to solve.

when 0 passes over 'F' a new 'F' should spawn at a different random location. My code seems to be the same as the video(There's is working).

any help is appriciated.

One problem i see is at line 43 if (i == fruitX && j == fruitY)
i represents row and fruitX the column.
Using more meaningful names can prevent this kind of problem.

Another problem is that you don't seed the random generator - best place would be setup.
