Can I assume declared but uninitialized variable to have the value of nil (for pointer type) or 0 (for numeric type)? Coming from Java, I was used to make those assumptions. I'm wondering whether it's the same for Objective-C


Assumptions will crash your program.

Instance variables are zeroed out upon instance allocation. All other variables follow standard ANSI C initialization rules.
