Chapter 5 - Control Structures II (Repetition)

infinite loop

a loop that continues to execute endlessly

loop control variable (LCV)

a variable that controls the end of the loop

counter-controlled while loop

a while loop that is used when you know how many items of data are to be read; the loop will continue until the condition designated by the counter is met or evaluates to false

flag-controlled while loop

uses a Boolean variable to control the execution of the loop

flag variable

a Boolean variable used to control the execution of a while loop

end-of-file (EOF)-controlled while loop

a while loop that stops when it reaches the end of the input file

Fibonacci number

a number in the Fibonacci sequence

Fibonacci sequence

a n = a n-1 + a n-2

for loop control

a loop control variable in a for loop; also called an indexed variable

nesting

a process that involves putting one control structure inside another

divisor

suppose that m and n are integers and m is nonzero. Then m is called a divisor of n if n = mt for some integer t; that is, when m divides n, the remainder is 0
