C173 Version 3 Language Agnostic UPDATED ACTUAL Questions and CORRECT
Answers
input A program gets data, perhaps from a file, keyboard, touchscreen, network, etc.
process A program performs computations on that data, such as adding two values like x +
y.
Output A program puts that data somewhere, such as to a file, screen, network, etc.
variable Used by programs to refer to data. It is a named item, used to hold a value.
flowchart A graphical language for creating computer programs.
Program A list of statements, each statement carrying out some action and executing one
at a time.
Run, execute Words for carrying out a program's statements.
String literal Text (characters) within double quotes.
Characters Any letter (a-z, A-Z), digit (0-9), or symbol (~, !, @, etc.).
newline Special two-character sequence \n whose appearance in an output string literal
causes the cursor to move to the next output line.
comment Text a programmer adds to a program, to be read by humans (other
programmers), but ignored by the program when executing.
, Moore's Law Engineers have reduced switch sizes by half about every 2 years.
bit A single 0 or 1.
byte Eight bits. Ex. 11000101
ASCII American Standard Code for Information Interchange. Code that is the numerical
representation of a character. Ex. Z would be stored in a computer as 1011010.
Pseudocode Text that resembles a program in a real programming language but is simplified to
aid human understanding.
assignment statement Assigns a variable with a value, such as X=5.
variable declaration declares a new variable, specifying the variable's name and type.
integer Variable type that can hold whole numbers.
Expression Can be a number, a variable name (numApples), or a simple calculation like
(numApples + 1).
Identifier A name created by a programmer for an item like a variable or function. Must be a
sequence of letters, underscores, and digits or start with a letter or underscore.
They are case sensitive.
Reserved word (or keyword) A word that is part of the language, like integer, Get or Put. These words cannot
be used as an identifier.
Naming conventions A set of style guidelines defined by a company, team, teacher, etc., for naming
variables.
Lower camel case Capitalize each word except the first, as in numApples.
Operator A symbol that performs a built-in calculation, like the + which performs addition.
Precedence rules An expression is evaluated using the order of standard mathematics.
Incremental development The progress of writing, compiling, and testing a small amount of code, then
writing, compiling, and testing a small amount more (an incremental amount), and
so on.
floating-point number Refers to the decimal point being able to appear anywhere ("float") in the number.
Ex. 98.6, 0.0006.
Floating-point literal A number with a fractional part, even if that fraction is 0.
Infinity or -Infinity Dividing a nonzero floating-point number by zero.
Not a number Indicates an unrepresentable or undefined value.
