# bitops
bitops is a C library for bitwise operations.
## Features
- Implements various bitwise operations such as set, clear, toggle, etc.
- Provides functions to count set bits, check if a number is a power of two, and more.
## Usage
To build the library and examples:
```bash
make all
make run_tests
```
To clean up generated files:
``` bash
make clean
```
