WGU C173 Study Guide UPDATED ACTUAL Questions and CORRECT Answers
- subtraction operator, outputs the difference between the two input numbers
!= a comparison operator used to compare if one operator is not equal to another
, % modulo operator, outputs the remainder of dividing the first number by the
second
* multiplication operator, outputs the product of the two input numbers
** exponentiation operator, outputs the result of multiplying <base> by itself <power>
number of times
/ division operator, outputs the result of dividing the first number by the second
+ addition operator, outputs the sum of the two input numbers OR concatenation
operator, joins two values together
< a comparison operator used to compare if one operator is less than another
< a comparison operator used to compare if one operator is less than another
<= a comparison operator used to compare if one operator is less than or equal to
another
= assignment operator, assigns a value
== a comparison operator used to compare if one operator is equal to another
> a comparison operator used to compare if one operator is greater than another
>= a comparison operator used to compare if one operator is greater than or equal
to another
abstraction Focus on the essential qualities of something rather than one specific example.
actors An Actor in a use case is anything with behavior who lives outside of your system,
outside of your application, but has a goal they want to accomplish within.
algorithm A set of commands that returns a value. This differs from a procedure, which is a
set of commands that doesn't necessarily have to return a value.
append() Mutates <List> by adding <Element> to the end of the list.
argument The inputs to a procedure. Also called operands.
attributes Characteristics of an object which may be used to reference other objects or save
object state information.
<name> = <expression> This is an assignment statement. A variable is named and also assigned a value or
expression. If multiple values are assigned to the same named variable, the last
assignment is the one used.
