[Solved] the number of execution time of 2 code will differ? [closed]

Question

It doesn’t matter which one you use, the program output will be identical; i++ and ++i are not the termination conditions in the for loop but are statements evaluated at the end of each iteration.

Note however that ++i will never be slower than i++; as conceptually an object copy has to be taken for the latter. A good compiler will optimise out the copy though.

And a point of style: please indent the line sum = sum + i;; it’s hard to read otherwise.
