State whether each of the following is true or false. If false, explain why.

  1. It's difficult to convert pseudocode into a Visual Basic program.
  2. Sequential execution refers to statements in a program that execute one after another.
  3. The If...Then statement is called a single-selection statement.
  4. Pseudocode closely resembles actual Visual Basic code.
  5. The Do While statement is terminated with the keywords End While.

Write two different Visual Basic statements that each add 1 to Integer variable number.


Write a statement or a set of statements to accomplish each of the following:

  1. Sum the odd integers between 1 and 15 using a While statement. Use Integer variables sum and count.
  2. Sum the squares of the even integers between 1 and 15 using a Do While...Loop repetition statement. Use Integer variables sum and count and initialize them to 0 and 2, respectively.
  3. Display the numbers from 5 to 1 in resultListBox using a Do Until...Loop and Integer counter variable counterIndex. Initialize counterIndex to 5.
  4. Repeat Exercise 4.4 (c) using a Do While...Loop statement.

Write a Visual Basic statement to accomplish each of the following tasks:

  1. Declare variables sum and number to be of type Integer.
  2. Assign 1 to variable number.
  3. Assign 0 to variable sum.
  4. Total variables number and sum, and assign the result to variable sum.
  5. Display "The sum is: " followed by the value of variable sum in resultLabel.

Combine the statements that you wrote in Exercise 4.5 into a program that calculates and displays the sum of the Integers from 1 to 10. Use a Do While...Loop statement to loop through the calculation and increment statements. The loop should terminate when the value of control variable number becomes 11.


Identify and correct the error(s) in each of the following (you may need to add code):

  1. The following loop should total the values from 1 to 50. Assume that value is 50.
    Do While value >= 0
       sum += value
  2. The following code should display the squares of 1 to 10 in resultListBox.
    Dim number As Integer = 1
    Do While number < 10
       resultListBox.Items.Add(number ^ 2)
    End While
  3. This segment should display the integers from 888 to 1000 in resultListBox. Initialize variable value to 888.
    Dim value As Integer = 888
    Do While value <= 1000
       value -= 1

State whether each of the following is true or false. If the answer is false, explain why.

  1. Pseudocode is a structured programming language.
  2. The body of a Do While...Loop is executed only if the loop-continuation test is false.
  3. The body of a While...End While is executed only if the loop-continuation test is false.
  4. The body of a Do Until...Loop is executed only if the loop-termination condition is false.
