Term
Loop
 Definition
Structure that allows repeated execution of a block of statements.
Term
Loop Body
 Definition
Block of statements that executes when the Boolean expression that controls the loop is true.
Term
Iteration
 Definition
One loop execution.
Term
While Loop
 Definition
Executes a body of statements continually as long as the Boolean expression that controls entry into the loop continues to be true.
Term
Definite Loop
 Definition
Loop that executes a specific number of times.
Term
Indefinite Loop
 Definition
One in which the final number of loops is a unknown.
Term
Loop Control Variable
 Definition
A variable whose value determines whether loop execution continues.
Term
Infinite Loop
 Definition
Loop that never ends.
Term
Empty Body
 Definition
A block with no statements in it.
Term
Incrementing
 Definition
To do this to a variable is to add 1 to its value.
Term
Decrementing
 Definition
To do this to a variable is to reduce its value by 1.
Term
Counter-Controlled Loop
 Definition
Definite loop.
Term
Invent-Controlled Loop
 Definition
Indefinite loop.
Term
Validating Data
 Definition
The process of ensuring that a value falls within a specified range.
Term
Primary Read/Primary Input
 Definition
The first input statement prior to a loop that will execute subsequent input statements for the same variable.
Term
Counting
 Definition
The process of eventually incrementing a variable to keep track of the number of occurances of some event.
Term
Accumulating
 Definition
The process of repeatedly increasing a value by some amount to produce a total.
Term
Add and Assign Operator (+=)
 Definition
Alters value of the operand on the left by adding the operand on the right to it.
Term
Subtract and Assign Operator (-=)
 Definition
Alters value of the operand on the left by subtracting the operand on the right by it.
Term
Divide and Assign Operator (/=)
 Definition
Alters value of the operand on the left by dividing the one on the right into it.
Term
Multiply and Assign Operator (*=)
 Definition
Alters value of the operand on the left by multiplying the operand on the right by it.
Term
Remainder and Assign Operator (%=)
 Definition
Alters the value of the operand on the left by assigning the remainder when the left operand is divided by the right.
Term
Prefix++/Prefix Movement Operator
 Definition
Adds 1 to a variable, then evaluates it.
Term
Postfix++/Postfix Increment Operator
 Definition
Evaluates a variable, then adds 1 to it.
Term
Prefix and Postfix Decrement Operators
 Definition
Subtract 1 from a variable. For example, if b=4; and c=b--;, 4 is assigned to c, and then after the assignment, b is deceased and takes the value 3. If b=4; and c=--b; b is decreased to 3, and 3 is assigned to be.
Term
For Loop
 Definition
Special loop that can be used when a definite number of loop iterations is required.
Term
Pretest Loop
 Definition
One in which the loop the control variable is tested before the loop body executes.
Term
The Do...While Loop
 Definition
executes a loop body at least one time; it checks the loop control variable at the bottom of the loop after one repetition has occured.
Term
Posttest Loop
 Definition
One in which the loop control variable is tested after the loop body executes.
Term
Inner Loop
 Definition
Contained entirely within another loop.
Term
Outer Loop
 Definition
Contains another loop.
Term
Do-Nothing Loop
 Definition
One that performs no actions other than looping.
Term
Loop Fusion
 Definition
The technique of combining two loops into one.
