Exam 6: Repeating Instructions

int counter = 0; while (counter < 100) { Console.WriteLine(counter); Counter++; } The first value printed with the program segment above is ____.

The only posttest loop structure available with C# is the ____________ loop structure.

The loop control structure used to move through a collection (group of data items) that does not require you to increment a loop control variable or test the expression to determine when all data has been processed is the ____ statement.

What is a requirement of the sentinel-controlled loop shared by counter-controlled loops?

Inside the for statement, when you place a semicolon after the parentheses without anything to the left of it, it indicates that no statement or a(n) ____________ statement is associated with the initialize portion.

int counter = 0; while (counter < 100) { Console.WriteLine(counter); Counter++; } Looking above, if the loop body was changed from counter++; to counter += 5;, how many times would the loop body be executed?

for (int i = 0; i < 5; i++) Console.Write(i + "\t"); Given the code snippet above, how many times will the loop body be executed?

The most appropriate sentinel value that might be selected for month of the year is ____.

Instead of requiring that a dummy value be entered after all values are processed, a ____-controlled loop initializes a variable on the outside of the loop and then evaluates the variable to see when it changes values. Its value is changed inside the loop body when the loop should exit.

When you know the number of times the statements must be executed, create a(n) ____________ loop.

An off-by-one error is a common problem associated with counter-controlled loops where the loop body is performed one too many or one too few times.

To write a recursive solution, a base case needs to be identified.

The while statement is the only type of loop construct that can be used to develop a sentinel-controlled loop.

A(n) ____________ is a loop that has no provisions for termination.

The third programming construct repetition is also called ____________.

A restriction on using the foreach statement is that you cannot change values in the collection. The access to the elements is read-only.

____________ loops are often used for inputting data when you do not know the exact number of values to be entered.

If a numeric variable is being changed by a consistent amount with each iteration through the loop, the while statement is the best choice of loop constructs.

Unlike the sentinel-controlled loop, the variable used with a state-controlled loop differs from the variable used to store the data that is being processed.

An advantage of sentinel-controlled loops is you do not need to know how many times the loop will be performed.
