In the interest of nitpicking: if a has value of 64512 then this evaluates to 0 ie false. Seeing that 'a' starts with initial value of 0 this will evaluate to zero every 64th iteration (2**16/1024, assuming unsigned int is 16 bits) of the loop. Probably not what was intended...but this does not always evaluate to true and this sort of statement might make sense in some circumstances.
