Found use of deprecated ios_base aliases CXX-W2031
Anti-pattern
Minor
The use of deprecated ios_base aliases such as ios_base::open_mode and ios_base::seek_dir is
considered an antipattern because they have been replaced by their non-deprecated equivalents.
This means that they may not be supported by future versions of C++.
For example, ios_base::open_mode has been replaced by std::ios_base::openmode.
