cfstream

cfstream is a lightweight C/C++ header-only library designed to make file input/output operations and redirection easier.

It is suitable for scenarios where you need to quickly switch between standard I/O and file I/O, such as printing debug information, saving and reading data through files, handling large amounts of input, Informatics Olympiad (OI) local testing and so on.
