Practice & Exercise

1. Identifier Naming Best Practices

Task: Write a function that checks if a given number is a perfect square.

• Requirements:

  • Name the function appropriately, following identifier naming best practices.

  • Use meaningful parameter names and return a boolean value indicating whether the number is a perfect square.

• Example Input: 16

• Expected Output: true

2. Class and Interface Naming

Task: Create a class that models a library book.

• Requirements:

  • Name the class and its properties in a way that clearly conveys their purpose.

  • Include properties for the book title, author, and ISBN number.

  • Implement a constructor to initialize these properties.

• Example Usage: Create a Book object with Title: "1984", Author: "George Orwell", ISBN: "123-4567890123".

3. Method and Property Naming

Task: Implement a method that calculates the factorial of a non-negative integer.

• Requirements:

  • Choose a clear and descriptive name for the method.

  • Use meaningful parameter names and ensure the return type is appropriate.

• Example Input: 5

• Expected Output: 120

4. Variable and Boolean Naming

Task: Write a function that determines if a person is a minor.

• Requirements:

  • Define a meaningful function name and use clear variable names for the parameters.

  • Return a boolean indicating if the person is under 18 years old.

• Example Input: 17

• Expected Output: true

5. Naming Patterns for Self-Documenting Code

Task: Create a function that reverses a string.

• Requirements:

  • Use an appropriate name for the function that reflects its action.

  • Ensure the parameter and return values are named clearly to avoid confusion.

• Example Input: "hello"

• Expected Output: "olleh"
