# Demo project

A small C++17 calculator used as the debug target for this example. The same
source code is copied into both the **remote** container (where it is compiled
and debugged) and the **devstation** container (where you edit and browse it).

## Build

```bash
cmake -DCMAKE_BUILD_TYPE=Debug -S . -B build
cmake --build build -j
```

This produces `build/debugapp` compiled with `-g3 -O0` (full debug info, zero
optimisation) and generates `compile_commands.json` for clangd.

## Good debugging targets

| Feature | Where to try it |
|---|---|
| **Breakpoints** | Any method in `Calculator` — e.g. `Calculator::divide` |
| **Conditional breakpoint** | In `runDemo()` at the `for` loop, set condition `i == 3` |
| **Variable inspection** | `m_accumulator`, `m_history`, `m_callCount` |
| **Watch expressions** | `m_history.size()`, `sum + diff` |
| **Call stack** | Step into `formatResult()` to see the stack frames |
| **Step over / into / out** | The `runDemo()` loop exercises all three |
