Answer 3

Decrementing

Question 4

a loop that executes a specific number of times; also called a counted loop.

Answer 4

Definite loop

Question 5

alters the value of the operand on the left by dividing the operand on the right into it.

Answer 5

Divide and assign operator (/=)

Question 6

executes a loop body at least one time; it checks the loop control variable at the bottom of the loop after one repetition has occurred.

Answer 6

do…while loop

Question 7

one that performs no actions other than looping.

Answer 7

Do-nothing loop

Question 8

a block with no statements in it.

Answer 8

Empty body

Question 9

an indefinite loop.

Answer 9

Event-controlled loop

Question 10

a special loop that can be used when a definite number of loop iterations is required.

Answer 10

for loop

Question 11

Adding 1 to the value of a variable.

Answer 11

Incrementing

Question 12

One in which the final number of loops is unknown.

Answer 12

Indefinite loop

Question 13

A loop that never ends.

Answer 13

Infinite loop

Question 14

Contained entirely within another loop.

Answer 14

Inner loop

Question 15

one loop execution.

Answer 15

Iteration

Question 16

The block of statements that executes when the Boolean expression that controls the loop is true.

Answer 16

Loop body

Question 17

a variablewhose value determines whether loop execution continues.

Answer 17

Loop control variable

Question 18

The technique of combining two loops into one.

Answer 18

Loop fusion

Question 19

A structure that allows repeated
execution of a block of statements.

Answer 19

Loop

Question 20

Alters the value of the operand on the left by multiplying the operand on the right by it.

Answer 20

Multiply and assign operator (*=)

Question 21

Contains another loop.

Answer 21

Outer loop

Question 22

Evaluates a variable and then adds 1 to it.

Answer 22

Postfix ++

Question 23

another name for Postfix ++.

Answer 23

Postfix increment operator

Question 24

one in which the loop control variable is tested after the loop body executes.

Answer 24

Posttest loop

Question 25

adds 1 to a variable and then evaluates it.

Answer 25

Prefix ++

Question 26

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 decreased and takes the value 3. If b = 4; and c = --b;, b is decreased to 3, and 3 is assigned to c.

Answer 26

Prefix and postfix decrement operators

Question 27

another name for Prefix ++.

Answer 27

Prefix increment operator

Question 28

one in which the loop control variable is tested before the loop body executes.

Answer 28

Pretest loop

Question 29

Another name for a priming read.

Answer 29

Priming input

Question 30

The first input statement prior to a loop that will execute subsequent input statements for the same variable.

Answer 30

Priming read

Question 31

Alters the value of the operand on the left by assigning the remainder when the left operand is divided by the right operand.

Answer 31

Remainder and assign operator (%=)

Question 32

alters the value of the operand on the left by subtracting the operand on the right from it.

Answer 32

Subtract and assign operator (–=)

Question 33

The process of ensuring that a value falls within a specified range.

Answer 33

Validating data

Question 34

executes a body of statements continually as long as the Boolean expression that controls entry into the loop continues to be true.

Answer 34

while loop
