Q136. - (Topic 2)
You are developing an application that contains a class named TheaterCustomer and a method named ProcessTheaterCustomer. The ProcessTheaterCustomer() method accepts a TheaterCustomer object as the input parameter.
You have the following requirements:
. Store the TheaterCustomer objects in a collection.
. Ensure that the ProcessTheaterCustomer() method processes the TheaterCustomer objects in the reverse order in which they are placed into the collection.
You need to meet the requirements.
What should you do?
A. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Dequeue() method to pass the objects to the ProcessTheaterCustomer() method.
B. Create a System.Collections.ArrayList collection. Use the Insert() method to add TheaterCustomer objects to the collection. Use the Remove() method to pass the objects to the ProcessTheaterCustomer() method.
C. Create a System.Collections.Stack collection. Use the Push() method to add TheaterCustomer objects to the collection. Use the Pop() method to pass the objects to the ProcessTheaterCustomer() method.
D. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Peek() method to pass the objects to the ProcessTheaterCustomer() method.
Answer: C
Explanation: A stack is the appropriate collection here. In computer science, a stack or LIFO (last in, first out) is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the last element that was added.

Q137. DRAG DROP - (Topic 2)
You are developing a C# application. The application includes a class named Rate. The following code segment implements the Rate class:
You define a collection of rates named rateCollection by using the following code segment:
Collection<Rate> rateCollection = new Collection<Rate>() ;
The application receives an XML file that contains rate information in the following format:
You need to parse the XML file and populate the rateCollection collection with Rate objects.
You have the following code: Which code segments should you include in Target 1, Target 2, Target 3 and Target 4 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
