How are items accessed in a stack?
- The item removed is the one that has been in the longest time.
- All items can be added to or removed from any location.
- The last item to be added becomes the first item removed.
- All items can be accessed or changed but not easily inserted or removed. -
ANSWER--The last item to be added becomes the first item removed.
What is the relationship between a parameter and an argument?
- A parameter is passed to a function by reference, whereas an argument is passed by
value.
- A parameter is a temporary variable in a function that receives the actual value of an
argument.
- An argument is an identifier in a function that receives the value called the
parameter.

- An argument is a value set in the code by a calculation, whereas a parameter is set
by user input. - ANSWER--A parameter is a temporary variable in a function that
receives the actual value of an argument.
Which programming language is considered to be a declarative language?
- Smalltalk
- BASIC
- Lisp
- Java - 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.
What does computational thinking involve?
