which one is better ?

new i
for( i ; ... )

for( new i ; ... )

[ddhoward]

The first one doesn't make any sense. It's either:

new i
for( ; ... )

or

for( new i ; ... )

Yeah? Yeah.

The second one, because you will access 'i' variable only in 'for' body. Use the first one if you need last 'i' value after loop (but better use another variable for this goal). If you will access variable only in this scope then declare it exactly in this scope.
Also with the second you will not have problem if you already declared variable 'i' in this scope. But be careful with the same variable naming.

P.S. Try not to reuse same variable for another goal, because this can break code understandability and may hard to modify code.

If you don't plan to use it below the "for" loop, then second.

The second one, first arg. from for() is initialization, so better do something like: for ( new i =0 ....

Or if you really want

static i
for( i = 0 ; ... )

That's actually the worst option.

static should only be used if the function where it is located is called extremely often or you need to retain the value of the previous execution. This use case, as far as we can tell, meets neither of these requirements.

If using "for (new i)" , you won't be able to use "i" outside the loop.
For example if you want to find first admin and you break loop you won't be able to use "i" next as admin id, it will be only in the loop .
