So the two behaviour you see are permitted, but neither is required i it is not a "general compiler behaviour", in the sense that all compilers/linkers are not required to give the same effect - and practically do not. Non-integral variables may have different behavior on host and target environments, non-static members can be mentioned in ctors, and for non-const variables the moment of initialization is more critical. You can initialize any object with the extern storage class specifier at global scope in C or at namespace scope in C++. uncover the hidden gem pick n pull tennessee int i = 0; Feb 7, 2014 · Analysis: Guess this program will work?
