You are developing an application that includes a class named Order. The application will store a collection of Order objects.

The collection must meet the following requirements:

• Internally store a key and a value for each collection item.

• Provide objects to iterators in ascending order based on the key.

• Ensure that item are accessible by zero-based index or by key.

You need to use a collection type that meets the requirements.

Which collection type should you use?

You are debugging an application that calculates loan interest.

The application includes the following code. (Line numbers are included for reference only.)

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?

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

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

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.)
