If i == 0 the file tackle for any file is leaked. On the other pop over to these guys hand, the ifstream for an additional file will properly close its file (on destruction). If you need to use an express pointer, rather then a source handle with certain semantics, make use of a unique_ptr or a shared_ptr with a custom made deleter:
