Your company asks you to create an undo buffer for the undo. The undo functionality must undo the most recent data modifications first. Besides this, the undo buffer only allows the storage of strings. You must ensure this two. In the options below, which code segment should you use?

• A.Queue<string> undoBuffer = new Queue<string>();

• D.Stack<string> undoBuffer = new Stack<string>();

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you are creating a class which contains a method named GetCurrentRate. The GetCurrentRate method retrieves the current interest rate and a variable named currRate that stores the current interest rate. You write serialized representations of the class. You have to write a code segment, when an instance of the class is deserialized, the segment updates the currRate variable with the current interest rate. So what code segment should you write?

• A.<OnDeserializing> _ Friend Sub UpdateValue(ByVal info As SerializationInfo) info.AddValue("currentRate", GetCurrentRate())End Sub
• B.<OnSerializing> _Friend Sub UpdateValue (ByVal context As StreamingContext) currRate = GetCurrentRate()End Sub
• C.<OnSerializing> _ Friend Sub UpdateValue(ByVal info As SerializationInfo) info.AddValue("currentRate", GetCurrentRate())End Sub
• D.<OnDeserialized> _Friend Sub UpdateValue (ByVal context As StreamingContext) currRate = GetCurrentRate()End Sub

You work as the developer in an IT company. Recently your company has a big customer.
The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. The customer needs to compress an array of bytes. So you are writing a method. The array is passed to the method in a parameter named document. You need to compress the incoming array of bytes and return the result as an array of bytes.
Which code segment should you use?

• A.MemoryStream strm = new MemoryStream();DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress);deflate.Write(document, 0, document.Length);deflate.Close();return strm.ToArray();
• B.MemoryStream inStream = new MemoryStream(document);DeflateStream deflate = new DeflateStream(inStream, CompressionMode.Compress); MemoryStream outStream = new MemoryStream();int b;while ((b = deflate.ReadByte()) != -1) { outStream.WriteByte((byte)b);} return outStream.ToArray();
• C.MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress);deflate.Write(document, 0, document.Length);deflate.Close();return strm.ToArray();
• D.MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress); byte[] result = new byte[document.Length];deflate.Write(result, 0, result.Length); return result;

You have just graduated from college, now you are serving the internship as the software developer in an international company. You develop an application where there's a method. You assign the output of the method to a string variable named fName. You are using the Microsoft Visual Studio 2005 IDE to examine the output of the method. You have to write a code segment. The code segment should print the following on a single line the message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
Besides this, the code segment must facilitates uninterrupted execution of the application at the same time. You must make sure of this.
In the options below, which code segment should you use?

• A.Debug.Assert(fName = "John", "Test Failed: ", fName)
• B.If fName <> "John" Then Debug.Print("Test Failed: ") Debug.Print(fName)End If
• C.Debug.WriteLineIf(fName <> "John", _ fName, "Test Failed")
• D.If fName <> "John" Then Debug.WriteLine("Test Failed: ") Debug.WriteLine(fName)End If
