I need a small, self-contained C++ program that takes raw text as input, applies a series of transformation and formatting operations, and returns the cleaned-up result. The focus is pure data processing—no graphics or UI—so everything can run from the command line or as a callable function inside a larger codebase. Typical transformations will include things like converting case, normalising whitespace, line-wrapping, trimming or inserting punctuation, and re-ordering segments when required. I don’t want anything hard-coded: please make the rule set easy to extend (e.g., by editing a configuration block or passing flags). Modern, standard-compliant C++ (17 or later) is preferred, and portable code is important as I’ll be compiling on Windows and Linux. Deliverables: • Well-commented source files and a simple build script (Makefile or CMake) • A short README explaining how to compile, run, and add new text rules • One or two working examples that show the transformations in action The program should compile cleanly with no external dependencies beyond the STL, handle large text files without noticeable slowdown, and follow clear, consistent formatting conventions. If this sounds straightforward, let me know your approach and timeline and we can get moving.
