CCBC Chapter 17 Recap

Which of the following describes the ideal process when running a build for a project?

• It should involve multiple complex steps and commands

• It should require an adventure through the codebase.

• It should require checking out numerous pieces from source control

• It should involve a single trivial operation followed by a straightforward command.

Is this a good header comment?

• No
• Depends on the context

• Yes

Generally, why are boolean arguments a red flag?

• It's a sign that a function does more than one thing

• They lower readability

• They are too abstract

• They are inefficient

Why is it recommended to avoid using multiple languages in a single file?

• To showcase proficiency in multiple languages
• To avoid confusion, errors, and difficulties in maintaining the code.
• To reduce file size

• To confuse other developers

What is the "The Principle of Least Surprise"?

• The Principle of Least Surprise refers to the most complex solution being the best.
• A system should behave in a way that most users would expect.
• A system should behave in a way that most users would not expect.
• A methadology used to reduce bugs

The fewer methods a class has, the better. The fewer variables a function knows about, the better. The fewer instance variables a class has, the better.

• Depends on the programming language
• False
• Partially true
• True

Why should we strive to eliminate "Feature Envy"

• To avoid exposing the internals

  of one class to another

• To speed up the development process

• To create more dependencies between classes

What is wrong with this function?

• It contains syntax erros

• It contains an unchecked cast

• It's intent is unclear

• The logic is incorrect

It is always ok to make a method be static

• False
• Depends on the project standards

• Sometimes
• True

What does it mean to "Make logical dependencies physical"?

• Ctrl + P

• Grouping related functions into a class

• Making dependencies implicit and hidden
• Organizing code to make dependencies explicit and visible
