Answer:
output.write("Hello, World")
Explanation:
A printWriter object (An instance of a class) is contained in a variable called output, to access the write method we use the dot (.) operator to access the write method of the output object and hence, output.write() outputs any string it takes as argument. this is a very interesting OOP (Object oriented programming concept).
Answer:
The answer is:
for intCounter As Integer = 1 To 3
Explanation:
This is the correct remaining part of the given question. "Your supervisor wants you to change the Do...Loop in the previous problem to a For...Next loop. He also wants the message to display only three times. Which of the following For clauses should you use?"
As in the given question the Do clause is changed to the correct For clause in the previous problem and Loop keyword is changed to the Next keyword for the For...Next loop.
Now the next thing to be changed about the Do loop is to display the message only three times using For clause as Do clause is changed to correct For clause. For that purpose the following statement is used to display the message only three times.
for intCounter As Integer = 1 To 3
Here the intCounter is used a count and its an integer type variable. 1 to 3 here show that this count variable i.e. intCounter in the for loop will execute three times hence displaying the message three times at each iteration of this for loop.
So this for loop variable will execute three times and at each iteration the message is displayed once. So at three iterations the message is displayed three times. Hence the correct for loop statement that displays the message three times is for intCounter As Integer = 1 To 3

when you are going to create a primary key, <span>In Object Explorer, right-click the table to which you want to add a unique constraint, and then click Design. In Table Designer tab, click the row selector for the database </span>column<span> you want to define as the </span>primary key<span>.</span>
