(Marks 20)

Problem Statement:
You are required to create a C# Console application using Visual Studio.
Your code should be able to calculate price for sacrificial animals that can be goat, sheep and camel separately while using the concept of POLYMORPHISM.
• Your code should work in such a way that you need to create 3 classes, one parent class i.e. Animal and other three derived classes that will be goat, sheep and camel.
• The function that needs to be override would be of Price Calculation.
• So, your code should work in such a way that at first you should enter the last NUMERIC character of your vu id as a number of animals you want to buy. (Note: You should also check if the last numeric character of your vu id is zero then your code should increment it with 1 so in any case your code should atleast buy one animal). After that, you should be asked for the first five numeric characters of your VUID which will be later used as a rent. Rent will be included in the price of animal that we will hard code.
• Now you need to make a menu/options as shown in the screenshot below, which will ask you if you want to calculate price for the sheep then press 1, if you want to calculate price for goat press 2, if you want to calculate price for camel then press 3, OR if you want to quit simply press 0 (Note: Your Loop should break when user presses 0)
• Your loop should run exactly the same number of times as you have entered for the number of animals you want to buy i.e. last numeric character of your vu id.
• You can use hard-coded values for the price of sheep, goat and camel like 50,000, 80,000, 100,000 respectively.
• Formula to calculate price is: Total Price = rent+price (according to the animal selected)
• Your output should be exactly same as shown in the screenshot below.
Required Output:
6ce1968f-49ce-497e-92b2-a050740f19c3-image.png

Note:
DO REMEMBER that you must use your VUID as an input in this program.

Submission details
Following Files Must be submitted in a single zip or rar file.
• .cs code file (file name should be your VUID)
• Screenshot of your output.
You are not required to submit the complete project, only copy required file from project folder.
If you do not submit any of the above-mentioned file you will be awarded Marks partially.

“The End”

@zaasmi
Universal Windows Platform (UWP)
UWP provides a common type system, APIs, and application model for all devices running on Windows 10. So, UWP enables development of universal apps for PC, tablet, Xbox, Surface Hub, HoloLens, or Internet of Things (IoT) devices.

UWP app developers get access to the Microsoft store that charges only 15 percent for non-gaming subscription-based apps, unlike Google Play Store and App Store. Other services include an execution environment (AppContainer) and Extension SDKs to call specialized APIs for different devices.

threadpool

public static class ThreadPool

Examples

using System; using System.Threading; public class Example { public static void Main() { // Queue the task. ThreadPool.QueueUserWorkItem(ThreadProc); Console.WriteLine("Main thread does some work, then sleeps."); Thread.Sleep(1000); Console.WriteLine("Main thread exits."); } // This thread procedure performs the task. static void ThreadProc(Object stateInfo) { // No state object was passed to QueueUserWorkItem, so stateInfo is null. Console.WriteLine("Hello from the thread pool."); } } // The example displays output like the following: // Main thread does some work, then sleeps. // Hello from the thread pool. // Main thread exits. void WaitCallback(Object state)
