About OutputTracer

OutputTracer is a focused tool for one job: predicting what a C++ program will print, and showing exactly how it gets there. Paste in code, and you'll see the expected output alongside a step-by-step trace of how variables change along the way.

It's built for students and self-learners practicing output prediction and dry-run questions — a skill that matters in coursework, exams, and everyday debugging, but that's easy to skip when you can just run the code and see what happens.

This is the first version of OutputTracer. Predictions and dry runs currently use representative example logic rather than a full C++ execution engine, which is planned for a future release.
