Answer 1

The option that is NOT a debugging method is:

changing constants to variables

While it may sometimes be useful in certain contexts (e.g., to allow for easier adjustments in certain scenarios), it is not considered a standard debugging method compared to the other options listed, which directly relate to identifying and fixing issues in code.

Answer 2

If the user enters a password that is too short, they will get an error message. Otherwise, they will get a welcome message. This is an example of which of these structures?

Responses

iteration

iteration

sequence

sequence

count-controlled loops

count-controlled loops

selection

Answer 3

This is an example of selection.

In this scenario, a decision is made based on the condition of the password length, resulting in one of two outcomes: displaying an error message for a short password or a welcome message for a valid one. This aligns with the concept of selection in programming, where different paths are chosen based on conditions.

Answer 4

Code that will repeat five times is an example of which of these structures?

Responses

selection

selection

iteration

iteration

sequences

sequences

query language

Answer 5

Code that will repeat five times is an example of iteration.

Iteration refers to the repetition of a block of code a certain number of times or until a specific condition is met. In this case, repeating the code five times clearly falls under the concept of iteration.

Answer 6

An hourglass symbol should appear on the screen until an image loads. What kind of structure will this require?

sequence

sequence

selection

selection

condition-controlled loop

condition-controlled loop

count-controlled loop

Answer 7

The situation described would require a condition-controlled loop.

A condition-controlled loop will continue to display the hourglass symbol while waiting for the image to load. The loop will terminate once the condition (the image loading) is met, hence it is driven by a condition rather than a fixed number of iterations.

Answer 8

A variable with letters and numbers is a:

string.

string.

integer.

integer.

constant.

constant.

Boolean.

Answer 9

A variable that contains letters and numbers is a: string.

In programming, a string is a data type used to represent text, which can include letters, numbers, and other characters. An integer would only represent whole numbers, a constant is a fixed value that does not change, and a Boolean represents true or false values.

What is the difference between an interpreted computer language and a compiled one?

Responses

An interpreted language is translated into binary all at once; a compiled language is translated line by line.

Answer 11

The correct response is:

A compiled language is translated into binary all at once; an interpreted language is translated line by line.

In summary:

• Compiled languages are translated entirely into machine code (binary) before execution, resulting in a standalone executable.
• Interpreted languages are executed line by line by an interpreter, which means the code is translated and executed simultaneously at runtime.
