Variable declaration in "for" loop initialization expression?

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

Thanks Graham! I think I will stick to the more restricted version. It's more compact and reliable indeed. It seems that C99 is set by default in XCode. What are the possible scenarios when I may need to use another dialect? Oleg. On Thu, Nov 18, 2010 at 1:52 PM, Graham Cox wrote: > > On 18/11

Calling a class method with the runtime ObjC API

Hi there, this is more a style question than anything else, but I'm sometimes perfectionist. ;) I am also aware it is somewhat borderline with Cocoa (belongs more to ObjC in general); sorry for this. I have designed a kind of a fake class which is, in reality, a simple collection of algorithms
