Local Variables
«

When talking about the loval variables in the book, there is an example of reduce method.
The book says:
Quote
The three local variables in the reduce method are set to values before they are used...
- p.140
But if you look at the code, one of these variables temp is not set to any values:
Quote
int temp;
Why?

It's not well-worded. All three variables are set before they're used; temp gets set a little later (inside the loop), but again, it gets set first before its value is used.
Thanks,
Steve
