DRAG DROP
You are developing an application by using C#. The application will output the text string “First Line” followed by
the text string “Second Line”.You need to ensure that an empty line separates the text strings.
Which four code segments should you use in sequence? (To answer, move the appropriate code segments to
the answer area and arrange them in the correct order.)
Select and Place:
Answer: 
Explanation:
Box 1:
First we create the variable.
Box 2:
We create the first text line.
Box 3:
We add a blank line.
The StringBuilder.AppendLine method appends the default line terminator to the end of the current
StringBuilder object.
Box 4:
Finally we add the second line.
Two sb.AppendLine() needed for the empty line separator.
Wrong, one AppendLine is correct
The results of the answer will be:
=============
var sb = new StringBuilder();
sb.Append(“First”);
sb.AppendLine();
sb.Append(“Second”);
Console.WriteLine(sb);
=============
First
Second
Barhoooom is correct.
I tested it in Visual Studio.
You need two times the sb.AppendLine(); to have a whiteline between the first and second string.
