Short Answer:

2. What values are displayed by the following code?
Const intMAX_SUBSCRIPT As Integer = 4
Dim intValues(intMAX_SUBSCRIPT) As Integer
Dim intCount As Integer

For intCount = 0 To intMAX_SUBSCRIPT
intVAlues(intCount) = intCount + 1

Next
For intCount = 0 To intMax_SUBSCRIPT
MessageBox.Show(intValues(intCount).ToString())
Next


Your Opinion:

Question 1. How many elements are in the following array?
Dim dblValues (3, 3) As Double

Question 2. Suppose an application uses a Timer control named tmrControl. Write a programming statement that sets the time between timer events at three seconds.


Find the error:
Question 1:
Dim intTable(10) As Integer ' Stores 11 values
Dim intIndex As Integer
Dim intMaxNum As Integer = 11
For intIndex = 0 To intMaxNum
intTable(intIndex) = CInt(InputBox("Enter the next value:"))
Next

Question 2:
' tmrTimer is a Timer control
tmrTimer.Interval = 0


ALGORITHM WORKBENCH:
Question 1:
Suppose you need to store information about 12 countries. Declare two arrays that may be used in parallel to store the names of the countries and their population

Question 2:
The arrays intNumberArray1 and intNumbersArray2 have 100 elements. Write code that copies the values in intNumberArray1 and intNumberArray2.

Question 3:
Suppose an application stores that following data about employees:
a) Name, stored in a lost box name 1stNames
b) Employees number, stored in an array of strings named strEmpNums
There is a parallel relationship between the list box and the array. Assume that the user has selected an employee’s names from the list box. Write code that displays (in a message box) the employees number for the selected employee.

Question 4:
Assume that dblValues is a two-dimensional array of Doubles with 10 rows and 20 columns. Write a “For Each” statement that sums all the elements in the array in the array and stores the sum in the variable dblTotal.

Question 5:
Suppose an application uses a two-dimensional array named intDays. Write code that sums each row in the array and displays the result.

Question 6:
Write code that uses a “For Each” statement to sum all of the elements in the array in Question 10.
