What does a programmer do first to use an existing programming library? - answers
Include the library
What relationship is common among a programming library's functions? - answers
Functions all relate to the same purpose.
What is an advantage of using a programming library? - answers The code has already
been tested.
Which language is dynamically typed? - answers Python
Which language is not built on object-oriented design principles? - answers C
A language substantially supports a programmer creating items like person, teacher,
and students. Each item has internal data and some operations.
Which characteristic describes that language? - answers 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? - answers Statically typed
A language uses tags around text to indicate how that text should be formatted.
Which characteristic describes a language having such tags? - answers Markup
What is a characteristic of a compiled language? - answers Converts to machine
language before running
What is a characteristic of an interpreted language? - answers Runs easily on different
kinds of machines
What is an advantage of interpreted programs? - answers They can be modified at run
time.
Which characteristic specifically describes a markup language? - answers Tags
surround text to describe desired formatting.
Which characteristic specifically describes interpreted languages? - answers They can
be run one statement at a time.
