CSC133 Intro to CS Using C++

Vocabulary II

iteration: one execution of a loop body
sentinel: value added to the end of the input to signal that there is no more data
count controlled loop: loop that executes until a particular number of iterations have been completed.
event controlled loop: loop that executes until a particular event occurs. Usually the event is the input of a sentinel value or reaching end of file on the input file.
relational operator: an operator that compares the magnitude of two values and results in value of true (1) or false (0). The relational operators are <, >, <=, >=, ==, and !=.
logical operator (boolean operator): an operator that combines true/false values and results in a value of true (1) or false (0). The logical operators are && (and), || (or), and ! (not). && and || are binary operators; ! is a unary operator.
logical expression (boolean expression): an expression that contains logical and/or relational operators and which evaluates to either true (1) or false (0).
function call: the statement that causes a function to execute
function definition: consists of the function header and the function body
function header: first line of a function definition; specifies the return type of the function, name of the function, and the type and name of each parameter.
function body: follows the function header; contains the statements that will be executed when the function is called. The function body is enclosed in braces { }.
function prototype: serves as the declaration for a function; specifies the return type of the function, name of the function, and the type of each parameter. A prototype is required if the function body appears after a call to the function.
actual parameter/argument: parameter in a function call.
formal parameter: parameter in a function header.
