# Task: rename across a small C project

`shop` is a tiny C program split over several files. Do the following, then stop:

1. Rename the function `compute_total` to `order_total` everywhere: the
   declaration, the definition, every call site and the comments. Nothing
   named `compute_total` may remain anywhere in the project.
2. `report.c` applies the 10% discount a second time, so the printed total is
   too low. Fix it so the discount is applied exactly once (`order_total`
   already applies it).
3. Run `make test` and make sure it passes.
4. Summarize the change in two or three sentences.

Find the call sites with the search tools instead of guessing. Edit only
what the task needs.
