Putting a composite statement in the condition of a for loop

Question

I have a contrived example to demonstrate the request for a specific functionality - I wonder if anyone has a clever trick to do this.

The following is a problem one

Answer 1

[In many ways this question should be closed as it's opinion based.]

This problem crops up often. I always opt for a solution that minimises the instructions in the iterative part.

{ /*don't pollute the outer scope with ii*/
    int ii;
    for (ii = 0; ii < 3; ++ii/*I've always preferred this to ii++*/) {
        printf("%d ", ii);
    }
    printf("%d\n", ii);
}

Ternaries, if statements etc. just obfuscate things. In my opinion.
