## Overview

This is a small terminal calculator: the user enters an expression, and the program parses space-separated tokens, checks them, computes addition or subtraction, and prints a result. The shown runtime entry point is `BSDCalculator.cpp`; it includes `Calc.hh` and uses its `calc` type. `AbsClass.cpp` appears to be a separate, incomplete program and is not shown as part of that runtime path. The contents of `Calc.hh` were not provided, so its internal responsibilities are not expanded here.

Main entry points: [`BSDCalculator.cpp`](https://github.com/thebugstudio/freebsd-cli-calculator/blob/main/BSDCalculator.cpp) (Calculator program), [`Calc.hh`](https://github.com/thebugstudio/freebsd-cli-calculator/blob/main/Calc.hh) (Calc token type)

## Components

### Other components

- **Terminal user**
- [Calculator program](https://github.com/thebugstudio/freebsd-cli-calculator/blob/main/BSDCalculator.cpp): `BSDCalculator.cpp`
- [Calc token type](https://github.com/thebugstudio/freebsd-cli-calculator/blob/main/Calc.hh): `Calc.hh`

## Connections

- Terminal user → Calculator program: enters expression (evidence: `BSDCalculator.cpp`)
- Calculator program → Calc token type: creates tokens (evidence: `BSDCalculator.cpp`)
- Calculator program → Terminal user: prints result (evidence: `BSDCalculator.cpp`)
