Describe computer programming : Commenting

The video tutorial emphasizes the importance of writing clean and well-structured code, highlighting the role of comments in making code more understandable. It explains how comments serve as notes for developers, using CSS, Scratch, and Python as examples. The tutorial demonstrates adding comments in Scratch and Python, showing how they aid in code reviews and maintenance. It also discusses practical uses of comments, such as preserving old code versions and improving code readability.

Why is it important for code to be clean and well-structured?

• To make it compatible with all programming languages

• To reduce the file size

• To ensure it is easily readable and understandable

• To make it run faster

What is the purpose of comments in code?

• To provide explanations for parts of the code

• To make the code run faster

• To change the functionality of the code

• To increase the file size

How are comments created in CSS?

• Using angle brackets

• Using forward slashes and asterisks

• Using hash symbols

• Using double slashes

What is a common practice in the coding world to ensure code quality?

• Writing code without comments

• Code reviews

• Releasing code without testing

• Ignoring errors

In Scratch, how can you add a comment to a code block?

• By double-clicking the block

• By right-clicking and selecting 'Add Comment'

• By dragging a comment icon

• By typing directly on the block

What character is used to add a comment in Python?

• Semicolon (;)

• Hash (#)

• Double slash (//)

• Asterisk (*)

How can comments improve code readability?

• By making the code longer

• By hiding errors

• By changing the code's functionality

• By providing explanations and organizing the code

What is a block comment in Python?

• A comment that spans multiple lines using triple quotes

• A comment that is written in a separate file

• A comment that is ignored by the compiler

• A comment that is only visible to the author

Why might a developer use comments to preserve old code?

• To permanently delete the old code

• To test new ideas without losing the original code

• To confuse other developers

• To make the code run faster

What is the benefit of using comments when working on a team project?

• To make the code more complex

• To increase the project's budget

• To ensure only the original author can understand the code

• To help team members understand the code's purpose and logic
