That line was part of an attempt to reduce the number checks for 'c' I had to perform (it wasn't equal to zero then). However I abandoned that process when I realized that it wasn't going to make the solution run too much faster so I just set it to be zero and forgot about it.

Googling I found that & is just bitwise AND and zero AND anything is zero.
