C173 WGU UPDATED ACTUAL Questions and CORRECT Answers
algorithm A sequence of instructions that solves a problem
Computational Thinking creating a sequence of instructions to solve a problem
ASCII American Standard Code for Information Interchange, and was developed in
1963. ASCII uses 7 bits per code, and has codes for 128 characters.
, Unicode Character encoding standard, 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.
= An assignment of a left-side variable with a right-side value. = is NOT equality as in
mathematics. Thus, x = 5 is read as "x is assigned with 5", and not as "x equals 5"
variable declaration Declares a new variable, specifying the variable's name and type
assignment statement Assigns the variable on the left-side of the = with the current value of the right-
side expression.
Identifier 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 (0-9)
start with a letter or underscore. Case sensitive.
Reserved word (or keyword) A word that is part of the language, like integer, Get, or Put. A programmer cannot
use a reserved word as an identifier.
Literal Specific value in code, like 2.
Operator A symbol that performs a built-in calculation, like the operator + which performs
addition
Unary minus - used as negative
Incremental development The process 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 A real number, like 98.6, 0.0001, or -666.667. The term "floating-point" refers to the
decimal point being able to appear anywhere ("float") in the number. A variable
declared as type float stores a floating-point number.
floating-point literal A number with a fractional part, even if that fraction is 0, as in 1.0, 0.0, or 99.573.
function call A statement that executes a function. It consists of the function name followed by
an argument list. Ex. SquareRoot(variable)
seed A built in integer when no previous random integer exists for RandomNumber().
Can specify seed random numbers with the function SeedRandomNumber() - this
can only be done once in a program before the first call to RandomNumber().
type conversion A conversion of one data type to another, such as an integer to a float.
type cast Converts a value of one type to another type.
A programmer can type cast an integer to float by multiply the integer by the float
literal 1.0. Ex: If myIntVar is 7, then myIntVar * 1.0 converts integer 7 to float 7.0.
