- Replacing empty constructor/destructor implementations with `= default` - Removing redundant `virtual` keywords from override methods - Replacing `NULL` and `0` with `nullptr` - Replacing C headers with C++ equivalents (`<cstdio>`, `<cstring>`, etc.) - Marking copy constructors/assignment operators as `= delete` for non-copyable classes - Converting `void` parameter lists to empty parameter lists - Replacing integer literals with appropriate boolean values
