WHERE OrderDate = #01/01/2011#
B. SELECT * FROM Orders
WHERE OrderDate = %01/01/2011%
C. SELECT * FROM Orders
WHERE OrderDate = '01/01/2011'
D. SELECT * FROM Orders
WHERE OrderDate = "01/01/2011"
Answer: C

Q4. You are writing code for a business application by using C#. Write the following statement to declare an array:
int[] numbers = { 1, 2, 3, 4, 5, };
Now, you need to access the second item in this array (the number 2). Which of the following expression should you use?
A. numbers[0]
B. numbers[1]
C. numbers[2]
D. numbers[3]
Answer: B
Q5. You create an ASP.NET Web Service that tracks the shipment of orders. The Web service includes a class nemed StatusService, which contains the following method:
Public string GetStatus()
{
/* additional code here */
}
You note that you can instantiate the StatusService class from a Web service client project, but the GetStatus method is not available. What could be the problem?
A. Only properties can be part of the public interface of a Web service.
B. You must mark the method with the WebService attribute.
C. The methods of a Web service can return only object data.
D. You must mark the method with the WebMethod attribute.
Answer: D
Q6. You are developing code that defines an InitFields method. The method takes two parameters of data type double and does not return any value to the calling code. Which of the following code segments would you use to define the InitFields method?
A. public double InitFields(double l, double w)
{
length = l;
width = w;
return length * width;
}
B. public void InitFields(double l, double w)
{
length = l;
width = w;
}
C. public void InitFields(double l)
{
length = l;
width = l;
return;
}
D. public double InitFields(double l, double w)
{
length = l;
width = w;
}
Answer: B
Q7. You are developing a sorting algorithm that uses partitioning and comparison to arrange an array of numbers in the correct order. You write a method that partitions the array so that the items less than pivot go to the left side, whereas the items greater than pivot go to the right side. The partitioning method has the following signature:
static int Partition (int[] numbers, int left,
int right, int pivotIndex) Which of the following algorithms should you use to sort the array using the Partition method?
A. static int[] QuickSort(int[] numbers,
int left, int right)
{
if (right > left)
{
int pivotIndex = left + (right - left) / 2;
pivotIndex = Partition(
numbers, left, right, pivotIndex);
QuickSort(
numbers, left, pivotIndex - 1);
QuickSort(
numbers, pivotIndex + 1, right);
}
return numbers;
}
B. static int[] QuickSort(int[] numbers,
int left, int right)
{
if (right > left)
{
int pivotIndex = left + (right - left) / 2;
pivotIndex = Partition(
numbers, left, right, pivotIndex);
QuickSort(
numbers, left, pivotIndex);
QuickSort(
numbers, pivotIndex + 1, right);
}
return numbers;
}
C. static int[] QuickSort(int[] numbers,
int left, int right)
{
if (right > left)
{
int pivotIndex = left + (right - left) / 2;
pivotIndex = Partition(
numbers, left, right, pivotIndex);
QuickSort(
numbers, left, pivotIndex - 1);
QuickSort(
numbers, pivotIndex, right);
} return numbers; }
D. static int[] QuickSort(int[] numbers,
int left, int right)
{
if (right > left)
{
int pivotIndex = left + (right - left) / 2;
pivotIndex = Partition(
numbers, left, right, pivotIndex);
QuickSort(
numbers, left, pivotIndex + 1);
QuickSort(
numbers, pivotIndex + 1, right);
}
return numbers;
}
