WGU (D278) Scripting and Programming
- Foundations: Pre-Assessment (PA)
What does a programmer do first to use an existing programming library? ANS: Include the library
What relationship is common among a programming library's functions? ANS: Functions all relate to the
same purpose.
What is an advantage of using a programming library? ANS: The code has already been tested.
Which language is dynamically typed? ANS: Python
Which language is not built on object-oriented design principles? ANS: C
A language substantially supports a programmer creating items like person, teacher, and students. Each
items has internal data and some operations.
Which characteristic describes that language? ANS: Object-oriented
A programmer wants a compiler to report an error if an integer variable is assigned with a string.
Which kind of language should the programmer use? ANS: Statically typed
A language uses tags around text to indicate how the text should be formatted.
Which characteristics describe a language having such tags? ANS: Markup
What is a characteristic of a compiled language? ANS: Converts to machine language before running
What is a characteristic of an interpreted language? ANS: Runs easily on different types of machines
, What is an advantage of interpreted programs? ANS: They can be modified at run time
Which characteristic specifically describes a markup language? ANS: Tags surround text to describe
desired formatting
Which characteristic specifically describes interpreted languages? ANS: They can be run one statement
at a time
Which characteristic specifically describes interpreted languages? ANS: They can run on any machine
having the right interpreter
A car drove 200 miles using 10 gallons of fuel.
Which operation should be used to compute the miles per gallon, which is 20? ANS: Division
Which operator should be used to determine if a number is evenly divisible by 5? ANS: %
A variable should hold a person's height in meters.
Which data type should the variable be? ANS: Float
A variable should hold the names of all past U.S. presidents.
Which data type should the variable be? ANS: String array
A program uses the number of seconds in a minute in various calculations.
How should the item that holds the number of seconds in a minute be declared? ANS: Constant integer
secondsPerMinute
