I think C++ uses a pragmatic approach: No overhead for explicit initialization. But everything that goes into the executable and doesn't have a specific value, will go into the BSS section, where it A) takes up no space and B) the OS will take care of zero initializing it _anyways_. If it is stored in the .exe, it is 0! -- Marco
