WGU D278 OBJECTIVE ASSESSMENT 70
COMPREHENSIVE QUESTIONS AND
COMPLETE SOLUTIONS
◉ Input.
Answer: A program gets data, perhaps from a file, keyboard,
touchscreen, network, etc.
◉ Process.
Answer: A programs performs computations on that data, such as
adding two values like x + y.
◉ Output.
Answer: A programs puts that data somewhere, such as to a file,
screen, network, etc.
◉ Computational thinking.
Answer: Creating a sequence of instructions to solve a problem.
◉ Algorithm.
Answer: A sequence of instructions that solves a problem.
,◉ Statement.
Answer: Carries out some action and executing one at a time.
◉ String literal.
Answer: Consists of text (characters) within double quotes, as in "Go
#57!".
◉ Cursor.
Answer: Indicates where the next output item will be placed in the
output.
◉ Newline.
Answer: A special two-character sequence \n whose appearance in
an output string literal causes the cursor to move to the next output
line. The newline exists invisibly in the output.
◉ Comment.
Answer: Text added to a program, read by humans to understand the
code, but ignored by the program when executed.
◉ Whitespace.
Answer: Refers to blank spaces (space and tab characters) between
items within a statement, and to newlines. Whitespace helps
, improve readability for humans, but for execution purposes is
mostly ignored.
◉ Pseudocode.
Answer: Text that resembles a program in a real programming
language but is simplified to aid human understanding.
◉ Assignment statement.
Answer: Assigns a variable with a value, such as x = 5. An
assignment statement's left side must be a variable. The right side is
an expression.Examples: x = 5, y = a, or z = w + 2.
◉ =.
Answer: In programming, = is an assignment of a left-side variable
with a right-side value. It does not represent equality like in
mathematics.
◉ Variable declaration.
Answer: Declares a new variable, specifying the variable's name and
type.
◉ Identifier.
Answer: A name created by a programmer for an item like a variable
or function. An identifier must: be a sequence of letters (a-z, A-Z),
