Why is it important to add comments to code?

• To make the code run faster

• To change the functionality of the code

• To improve the readability of code

• To increase the number of lines of code

What can happen to programs as they grow and expand?

• They can become less complicated to read

• They can become shorter

• They can become more complicated to read

• They can require fewer comments

Where is it considered good practice to insert multi-line comments in a program?

• At the bottom of the program

• In the middle of the program

• At the top of the program

• Outside the program file

What should multi-line comments contain?

• Only the name of the program

• Only the date and description of what the program will do

• The name of the program, author, date, and description of what the program will do

• Random notes and reminders

How are multi-line comments started and ended in a program?

• With a single quotation mark

• With three quotation marks

• With a slash and asterisk (/* */)

What symbol is used to add single line comments in code?

• //

• /*

• #

What is the purpose of using single line comments in code?

• To change the functionality of the code

• To compile the code faster

• To explain certain aspects of the code

• To create a new variable

Single line comments are also used to:

• Execute a specific line of code

• Highlight different sections

• Import external libraries

• Define functions

What is a variable in the context of programming?

• A. A constant value that does not change throughout the program

• B. A storage location reserved in memory to store a value used within a program
