Exam 6: Repeating Instructions

You must tell the user what value to type to end the loop for ____.

You often need to do a "prime the read" for counter controlled loops which means that you would input a value before going into the body of the loop.

Using the break or continue statements with a loop violates the single entry and single exit guideline for developing a loop.

The do...while statement is a posttest loop,which means that the conditional expression is tested before any of the statements in the body of the loop are performed.

With while loops,if the conditional expression evaluates to true,the body of the loop is not performed;control transfers to the statements following the loop.

An option other than looping that can be used to repeat program statement is _____________.With this technique a method calls itself repeatedly until it arrives at the solution.

The third programming construct repetition is also called ____________.

With counter controlled loops,it is important to think through and ____________ to ensure they have been taken into consideration.You should always check the initial and final values of the loop control variable and verify that you get the expected results at the boundaries.

Scope refers to the region in the program in which you can use the variable.

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

Class diagrams show the data,method,and property members of a class.

Windows applications use an event-driven model to manage the interaction between the user and the GUI by handling the repetition for you.

for (int i = 0; i < 5; i++) Console.Write(i + "\t"); -The conditional expression used with the for statement ____.

An interpretation of the while statement is "while the condition is true,perform statement(s)".

int counter = 0; while (counter < 100) { Console.WriteLine(counter); counter++; } -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.

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

The _____________ method of the MessageBox class displays a predefined dialog box that can contain text,captions for the title bar,special buttons,and icons.

A sentinel controlled loop is also called a flag-controlled loop.

int inner; for (int outer = 0;outer < 3;outer++) { For (inner = 1;inner < 2;inner++) Console.WriteLine("Outer: {0}\tInner: {1}",outer,inner); } The nested for statement above displays how many lines of output?
