Exam 5: Working With Loops

The while loop is a loop that executes as long as a tested condition continues to evaluate as false.

When working with the while or until loops, the do or : are mutually exclusive and can be omitted if the loop is spread out over more than one line.

The each method is a very commonly used looping method. This method is supported by a number of different Ruby classes, including all of the following except ____.

Ruby's built-in language looping constructions include which of the following?

The until loop is the opposite of the while loop. Instead of looping while a tested expression remains true, the until loop executes until ____.

The for...in loop is designed to process collections of data, including:

An iterator is a variable used to process the contents of a list of items.

A feature unique to the for…in loop is that it is built to automatically repeat once for every element stored in an array.

When combined with conditional logic, loops provide the basis for developing the programming logic needed to process and validate user input.

The each method automatically iterates once for each item stored in the array.
