Can the update statement in for loop work with both postfix with prefix? (i++ and ++i)

Question

For example

#include<stdio.h>
int main()
{
    for(int i=1; i<=10; ++i)
    {
        printf("%d \n", i);
    }
    return 0;
}

Can the ++i in the for loop updation be i++?

Maybe. If you tried it, and it didn't work, can you ask about that? — jxh, Oct 06 '20 at 06:47
The question is unclear to me, please specify why "Yes." (after a quick experiment of your own) is not the answer. — Yunnosch, Oct 06 '20 at 06:47
Indeed. https://stackoverflow.com/questions/484462/difference-between-pre-increment-and-post-increment-in-a-loop — bhizmi, Oct 06 '20 at 06:48
Postfix or prefix only matters if you mix them with other operators in the same expression. Which is, as it turns out, very bad and dangerous practice. So generally you don't need worry about postfix vs prefix: if you find a use for one over the other, it just means that your code is ugly and dangerous. — Lundin, Oct 06 '20 at 06:53
(And yes `*a++ = *b++` is a common way to implement certain copy functions, but it was never well-written C.) — Lundin, Oct 06 '20 at 06:54
@Lundin what why where?! K&R most certainly uses `while ((s[i++] = t[j++]) != '\0') /* copy t */;` — Antti Haapala -- Слава Україні, Oct 06 '20 at 07:18
@AnttiHaapala And the Tyrannosaurus was most likely a scavenger. So what? — Lundin, Oct 06 '20 at 08:53
So you're saying that K&R didn't know how to write C well. Ok :D Back in the days with single-pass compilers it *was* well-written C. — Antti Haapala -- Слава Україні, Oct 06 '20 at 09:16

Can the ++i in the for loop updation can be i++?

Answer is Yes

You can check the o/p in both the case. It print the same value.
