Question

question: 14
what is the correct keyword to create a constant variable?
○ constant
○ const
○ let
○ def

question: 15
which of the following is part of the navigators role in pair - programming?
○ defining all of the functions
○ focusing on the task at hand
○ thinking of alternative ways to solve the problem
○ initializing the variables

Explanation:

Question 14

To determine the correct keyword for a constant variable:

• "constant" is not a standard keyword in most programming languages (e.g., JavaScript, C++).
• "const" is the standard keyword (e.g., in JavaScript, C++) to declare a constant variable whose value cannot be reassigned.
• "let" is used to declare a variable that can be reassigned (in JavaScript).
• "def" is used for function definitions (e.g., in Python) and not for constants.

In pair - programming, the navigator's role is to review the code, think about the overall approach, and consider alternative solutions.

• "defining all of the functions" is more of the driver's task (the one typing code).
• "focusing on the task at hand" is a general task but not specific to the navigator.
• "thinking of alternative ways to solve the problem" aligns with the navigator's role of providing a broader perspective.
• "initializing the variables" is part of coding, done by the driver.

Answer:

B. const
