## Features
- Determines whether the number is **prime**.
- Checks if the number is an **Armstrong number**.
- Identifies if the number is **perfect**.
- Classifies the number as **odd** or **even**.
- Calculates the **sum of digits**.
- Retrieves a **fun fact** about the number from [Numbers API](http://numbersapi.com/).
