Problems with [NSArray count]

Hi,

I'm returning to Cocoa after quite a long break, and it seems that I'm 
a little rusty...

All I want to do is find out the number of items in an NSArray and 
store that as a variable, which I can then find the square root of.

The docs tell me that [NSArray count] returns an NSUInteger, but 
exactly WHAT one of these is, or how I use it is baffling me.

a simple

   int i = [myArray count];

crashes out, and I've tried various other types of variable to no 
avail. Any thoughts? Am I missing something blindingly obvious here?

Thanks,
Peter
