# Module 01: C++ Fundamentals

## Learning Goals

- Understand the structure of a C++ program (`main`, headers, translation units)
- Work with fundamental types (`int`, `double`, `bool`, `char`)
- Use literals, constants, and basic I/O
- Apply arithmetic, relational, and logical operators
- Read and write formatted output

## Exercises

| Exercise | Topic | Standard |
|----------|-------|----------|
| `hello_world` | First program, returning values from functions | C++17 |
| `variables_and_types` | Types, `auto`, type aliases | C++17 |
| `operators` | Arithmetic, comparisons, bitwise ops | C++17 |
| `basic_io` | Streams, string formatting | C++17 |

## How to Work

1. Open the exercise header in `include/` to see the required API.
2. Implement the functions in `src/`.
3. Run the corresponding test target in CLion or with CTest.
4. All tests must pass before moving on.

## Run Tests (CLion)

Select a target like `01_fundamentals_hello_world` and click Run, or use:

```bash
cmake --build build --target 01_fundamentals_hello_world
ctest --test-dir build -R 01_fundamentals_hello_world
```
