If i == 0 the file deal with for any file is leaked. Conversely, the ifstream for one more file will appropriately shut its file (upon destruction). If you must use an specific pointer, instead of a source handle with distinct semantics, use a unique_ptr or possibly a shared_ptr by using a custom made deleter:
