What are the basic instruction types of a computer program? - correct answer - input
- process
- output
What is a variable? - correct answer refers to data that programs use. A variables value changes
or is "varying" as a program assigns a variable with new values.
What is the equation for a triangles area? - correct answer base x height divided by 2
base x height / 2
How do you find the average of a set of numbers? - correct answer The sum of the numbers
divided by the total number of values in the set.
For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of
the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6
What is computational thinking? - correct answer creating a sequence of instructions to solve a
problem
What is an algorithm? - correct answer A sequence of instructions that solves a problem
What is a flowchart? - correct answer a graphical language for creating computer programs
What is a program? - correct answer A list of statements, each statement carrying out some
action and executing one at a time
What is a tool that runs a programs statements? - correct answer Interpreter
What is a specific action in a program? - correct answer a statement
What shape is used for an input and output statement? (zyflowcharts) - correct answer
parallelogram
What represents a new line? - correct answer \n
What is a comment? - correct answer text a programmer adds to a program, to be read by
humans to better understand the code, but ignored by the program when executing.
Comments begin with //
What should not include whitespace? - correct answer variable names and digits of a number

When did the industrial age start? - correct answer late 1700's
When did the information age start? - correct answer 1990's
What is an embedded computer? - correct answer text a programmer adds to a program, to be
read by humans to better understand the code, but ignored by the program when executing.
What is a character? - correct answer s a letter (a, b, ..., z, A, B, ..., Z), symbol (!, @, #, ...), or
single-digit number (0, 1, ..., 9)
What does ASCII stand for? and when was it developed? - correct answer developed in 1963
American Standard Code for Information Interchange
How many bits per code does ASCII use? - correct answer 7 and has codes for 128 characters
Unicode - correct answer published in 1991 whose codes can have more bits than ASCII and
thus can represent over 100,000 items, such as symbols and non-English characters.
What is Pseudocode? - correct answer text that resembles a program in a real programming
language but is simplified to aid human understanding.
What is an assignment statement? - correct answer Assigns a variable with a value, such as x=5.
That statement means x is assigned with 5, and x keeps that value during subsequent
statements, until x is assigned again.
What is a variable declaration? - correct answer declares a new variable, specifying the
variables name and type.
example: variable type of integer holds whole number values. userAge = 23
Integer values are automatically initialized with 0 until a value is assigned
What is an identifier? - correct answer A name created by a programmer for an item like a
variable or function
must be a sequence of letters (a-z, A-Z) underscores, and digits and start with a letter
Case sensitive

What is a reserved word? (or keyword) - correct answer a word that is part of the language, like
integer, Get or Put
reserved words cannot be used as an identifier
What is a naming convention?
and what are the 2 most common conventions? - correct answer A set of style guidelines
defined by a company, team, teacher, etc for naming variables
- camel case
- underscore separated
What is an expression? - correct answer A combination of items, like variables, literals,
operators, and parentheses, that evaluates to a value and commonly are used on the right side
of an assignment statement.
Example: 2 * (x + 1)
(an assignment would be y = 2 * 1)
An expression can just be a variable or a literal
What is a literal? - correct answer a specific value in code, like 2
commas are not allowed in integer literals. Example: 1,333,555 is written as 1333555
What is an operator? - correct answer a symbol that performs a built in calculation, like the
operator + performs addition
What is the order of precedence for arithmetic operators? - correct answer 1. ( )
2. unary - used for negation (unary minus)
