Difference between i++ and ++i in a loop?

I know that a++ return the original value of a and then add one to a, while ++a increment a by one and return a. But I can´t see how this is different in a for loop.

This is getting closed in a matter of minutes. But you are correct that a decent compiler would make this a non-issue. — Captain Giraffe, Sep 23 '12 at 20:23

well if you are operation on an array in the for loop that is zero indexed and you use x++ then the first value to be processed will be the 0 index value however if you use ++x then the value to be processed first will be the 1 index.

In simpler terms:

x++ increments the value of variable x after processing the current statement.

++x increments the value of variable x before processing the current statement.

No. The question was asked in the context of a for loop. – Captain Giraffe Sep 23 '12 at 20:28
