What is one standard rule for a variable name?
The name should have an appropriate meaning.
The name must start with a lowercase letter.
The name must start with the type designation.
The name must use hyphens between words. - ANSWERThe name should have an
appropriate meaning.

What is a list?
A varying-length, ordered collection of homogeneous items that allows for easy access,
insertion, and removal
A group of related attributes stored as individual fields under a single name and treated
as a single concept
, A fixed-length collection of homogeneous items that can each be accessed by its
position
A group in which individual elements are accessed from the same end that is called the
top - ANSWERA varying-length, ordered collection of homogeneous items that allows
for easy access, insertion, and removal
How are items added to and removed from a stack?
All items can be added to or removed from any location.
All items can be accessed or changed but not easily inserted or removed.
The first item to be added becomes the first item removed.
The item removed is the one that has been in the shortest time. - ANSWERThe item
removed is the one that has been in the shortest time.
The collection of customers for a small business is stored in such a way that a customer
can be easily accessed, deleted, or added. What is the data structure called for in this
programming situation?
Queue
Record
Stack

What describes a reference parameter?
Stops the content of the argument from changing anywhere in the program
Passes a copy of the content in an argument to the function
Allows the user to type in the content of an argument at runtime
Passes the address, rather than the content, of the argument to the function -
ANSWERPasses the address, rather than the content, of the argument to the function
The code shows a subprogram and a call to that subprogram.
my_function(num_a)
num_c = process(num_a)
store(num_c)num_b = my_function(num_d)
Which variable name represents an argument?
num_a
num_b
num_c
num_d - ANSWERnum_d
What does the object-oriented programming paradigm do to solve a programming
problem?
Uses the structures of logic to deduce the answer from the facts and rules
Enforces a specific type on each variable and strict rules about how types are used
Organizes a program into smaller components that bundle together fields and methods
