Hi,
I know, this is a very basic question, but after learning so many
programming languages, my head seems like a mess.
In C that is in Objective-C, what is the correct/preferable way to
declare the counter variable in a for loop?
Type i;
for (i = 0; i < N; ++ i) { statements }
or
for (Type i = 0; i < N; ++i) { statements }
Regarding for...in... loop, the docs are very clear that both the
following declarations are valid:
Type existingItem;
for ( existingItem in expression ) { statements }
and
for ( Type newVariable in expression ) { statements }
But what about for (;;) ? The compiler does not point to it as an
error if I declare the counter inside the for () brackets, but I want
to make sure!
Thanks
Oleg.
