ANSWERS) ALREADY GRADED A+ | GUARANTEED PASS.
Which value is stored as an integer in computer programming? -
Correct Answer > 21. Rationale: The integer data type is used to
represent positive or negative whole numbers without fractional parts.
Which coding construct repeats a task while a condition is true? -
Correct Answer > Iteration. Rationale: The iteration construct, or the
looping construct, uses a while statement to perform the same task
over and over again as long as the condition is true.
A web browser puts websites into a viewing history log and accesses
the most recent one when the back button is clicked. Which data
structure would be appropriate for this situation? - Correct Answer >
Stack. Rationale: A stack is an ordered group of items that can only be
accessed at one end, called the top of the stack. Items can be pushed
onto and popped off of this end. In this case, the only item needing to
, be accessed is the most recently added item. Therefore, a stack is most
appropriate for storing the data.
What is the relationship between a parameter and an argument? -
Correct Answer > A parameter is a temporary variable in a function that
receives the actual value of an argument. Rationale: A parameter is
defined within a function and serves as a temporary placeholder. The
argument is the actual value that is passed to the function and gets
temporarily stored in the parameter.
Which programming language is considered to be a declarative
language? - Correct Answer > Lisp - The declarative programming
paradigm is a model in which the results are described, but the steps to
accomplish the results are not stated. There are two basic models
within this paradigm, functional and logical. Lisp is an example of
declarative.
How are items accessed in a stack? - Correct Answer > The last item to
be added becomes the first item removed (LIFO). Rationale: A stack is
an ordered group of items that can only be accessed at one end, called
