Hi, is it possible to inialize an array of integers(or chars or whatever) declared globally to all zeroes at compile time?
Ie. Can I write something like this int a[100] = {0} and be sure that all elements of 'a' will initially be zero when I execute my program?
Thanks.
Interesting, why is this? I thought that this wasn't the case for local var's because C++ didn't want to force you to do that (inefficient), but why would they do so for globals?
I guess because globals have their contents set at compile time so there wouldnt be any efficiency hit...the memory from the executable would just be mapped as is from the fileOriginally posted by roktsyntst

Or runtime.
3.6.2 Initialization of non-local objects [basic.start.init]
The storage for objects with static storage duration shall be zero-initialized before any other initialization takes place...Objects of POD types (...) shall be initialized before any dynamic initialization takes place.
