You need to ensure that the application accepts only integer input and prompts the user each time non-integer input is entered.

Which code segment should you add at line 19?

A. If (!int.TryParse{sLine, out number))

B. If ((number = Int32.Parse(sLine)) = = Single.NaN)

C. If ((number = int.Parse (sLine)) > Int32.MaxValue)

D. If (Int32.TryParse(sLine, out number))

Correct Answer: A


QUESTION 44

clip_image004

You have the following requirements:

-The debugger must break execution within the Calculatelnterest() method when the loanAmount variable is less than or equal to zero. -The release version of the code must not be impacted by any changes. You need to meet the requirements.

What should you do?

A. Insert the following code segment at tine 05: Debug.Write(loanAmount > 0);

B. Insert the following code segment at line 05: Trace.Write(loanAmount > 0);

C. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0);

D. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);

Correct Answer: C


QUESTION 45

You are developing an application that will process orders. The debug and release versions of the

application will display different logo images.

You need to ensure that the correct image path is set based on the build configuration. Which code segment should you use?

clip_image006

A. Option A

B. Option B

C. Option C

D. Option D

Correct Answer: C


QUESTION 46

You are testing an application. The application includes methods named Calculatelnterest and LogLine. The Calculatelnterest () method calculates loan interest. The Logl_ine() method sends diagnostic messages to a console window.

The following code implements the methods. (Line numbers are included for reference only.)

clip_image008

You have the following requirements:

-The Calculatelnterest() method must run for all build configurations. -The LogLine() method must run only for debug builds.

You need to ensure that the methods run correctly.

What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A. Insert the following code segment at line 01:

#region DEBUG

Insert the following code segment at line 10:

#endregion

B. . Insert the following code segment at line 10: [Conditional(MDEBUG")]

C. . Insert the following code segment at line 05:

#region DEBUG

Insert the following code segment at line 07:

#endregion

D. . Insert the following code segment at line 01:

#if DE30G Insert the following code segment at line 10: #endif

E. Insert the following code segment at line 01: [Conditional(MDEBUG")]

F. Insert the following code segment at line 05:

#if DEBUG

Insert the following code segment at line 07:

#endif

G. . Insert the following code segment at line 10:

[Conditional("RELEASE")]

Correct Answer: BF


QUESTION 47

You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve order

information from a Microsoft SQL Server database. The application includes the following code. (Line numbers are included for reference only.)

clip_image010

The application must meet the following requirements:

-Return only orders that have an OrderDate value other than null.

-Return only orders that were placed in the year specified in the OrderDate property or in a later year.

-Not raise an exeption

You need to ensure that the application meets the requirements. Which code segment should you insert at line 08?

A. Where order.OrderDate.Value != null && order.OrderDate.Value.Year > = year

B. Where order.OrderDate.Value = = null && order.OrderDate.Value.Year = = year

C. Where order.OrderDate.HasValue && order.OrderDate.Value.Year > = year

D. Where order.OrderDate.Value.Year = = year

Correct Answer: C
