++i
i++

when each of these is used in a loop such as below,
   shouldn't the decision to pre-fix or to post-fix
   affect the output of said loop?

the following, compiled and run under djgpp(gcc272),
with the condition of the for loop being ++i or i++,
seems to result in the same for both cases.

such shouldn't be the case, should it?
