counter-controlled loop
loop that uses a variable simulating a counter to keep track of the number of iterations
relational operators
operators used to test variables to see if one is greater or less than another variable or value (>,<, >=, <=)
iteration
one of the three basic constructs that enables you to write instructions that can be repeated
if selection statement
used in combination with a conditional expression to facilitate specifying alternate paths based on the result of the conditional expression
logical negation operator
operator (!) that negates its operand; also called the NOT operator
simple sequence
one of the three basic constructs where execution begins with the first statement and continues sequentially one statement after the next until the end of the method is encountered
jump statement
statement used to transfer control to a different portion in the program; examples include the break statements used with switch statements
empty bodied loop
a loop that has no statements; can be created by placing a semicolon on the end of the conditional expression
loop condition
logical condition to be tested that appears in the conditional expression of a loop
the test
an expression enclosed inside parentheses that produces a Boolean result
NOT equal
relational operator denoted by combining exclamation point and equal symbol without a space (!=)
assignment operator
single equal symbol (=)
indefinite loop
loop used for inputting data when the exact number of values to be entered is not known; when the loop should terminate, an extreme or dummy value is entered
basic programming constructs
three basic general purpose categories of programming statements that include simple sequence, selection, and iteration
automatic garbage collection
when a variable is out of scope, its space is automatically released back to the operating system for reuse
iteration
structure that enables you to identify and block together one or more statements to be repeated based on a predetermined condition; also called repetition
ternary operator
provides another way to express a simple if...else selection statement (?
selection statement
one of the three basic constructs used for decision making that allows you to deviate from the sequential path
pretest loop
loop where the conditional expression is tested before any of the statements in the body of the loop are performed
nested if...else statement
when you place an if statement inside another if statement
loop control variable
variable simulating a counter used in a counter-controlled loop to keep track of the number of iterations
fall through
executing code from more than one case
repetition
structure that enables you to identify and block together one or more statements to be repeated based on a predetermined condition; also called iteration
lining up
for matching elses with if statements, the else goes with the closest previous if that does not have its own else
test condition
an expression enclosed inside parentheses that produces a Boolean result
case statement
multiple selection structure; also called switch statement
right-associative
operations are performed from right to left
short-circuit evaluation
stopping the evaluation as soon as the value of the entire expression is known
state-controlled loop
loop used when the exact number iterations is not known; loops stop when a certain state is reached—value of a variable changed; also called a flag-controlled loop
conditional operator
provides another way to express a simple if...else selection statement (?
null (empty) statement body
placing a semicolon onto the end of the conditional expression
overloaded operators
operators defined to perform differently based on their operands
conditional expression
an expression enclosed inside parentheses that produces a Boolean result
selector
the expression used with the switch statement to determine which case should be executed
infinite loop
loop that has no provisions for termination
flag-controlled loop
loop used when the exact number of iterations is not known; loops stop when a certain state is reached—value of a variable changed; also called a state-controlled loop
event-driven model
repetition is handled in Windows and Web applications using this model; once the program is launched, the interaction between the user and the GUI is handled by responding to events
logical operators
used to combine conditional expressions (&&, ||)
equality operator
two equal symbols together (==)
sentinel-controlled loop
loop used for inputting data when the exact number of values to be entered is not known; when the loop should terminate, an extreme or dummy value is entered; also called indefinite loop
NOT operator
operator (!) that negates its operand; also called the logical negation operator
short-circuiting logical operators
operators (&&, ||) that enable doing as little as is needed to produce the final result through short-circuit evaluation
one-way selection statement
an if statement without an else
switch statement
multiple selection structure; also called case statement
precedence of the operators
the order in which the individual operators are evaluated
off-by-one error
executing the loop one too many or one too few times
array
data structure that allows multiple values to be stored under a single identifier
left-associative
operations are performed from left to right
prime the read
input a value before going into the body of the loop
two-way if statement
an if statement that includes an else statement
