List and explain five EIGRP commands that can be used at the command line to support EIGRP on a router. Include any relevant parameters of the command that can benefit the network engineer supporting the router

Create an Interface DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count (int type) and itemCost (double type). Create a class BulkDiscount that implements Interface DiscountPolicy. The BulkDiscount class has two proprieties: theMinimum (int type), and percent (double type). It should have a constructor that sets the parameters, minimum and percent to a given values. It should define the method computeDiscount so that if the quantity (count) purchased of an item is more than minimum, the discount is calculated as count*itemCost*percentOff/100.0, otherwise, discount will be equal=0.0; Write a test program that tests your method. Create at least three objects of BulkDiscount class and print out their discount values. (JAVA)

Question 1. Move your algorithm/pseudocode/outline into Code:Blocks and create a "shell" program. (The shell program shouldn't do any of the final work, but it should have comments where the final code will go and should compile and run.)

If you were designing sound for a game, in what instances would you create your own sounds using foley (or by recording sounds from the environment) versus utilizing pre-existing material from a library? Similarly, when would you create (or hire someone to create) original music versus licensing pre-existing material from a library or label?

In C Sharp with the use of the Try and Catch method create an application that displays the contents of the Teams.txt file in a ListBox control. When the user selects a team in the ListBox, the application should display the number of times the team has won the World Series in the time period from 1903 through 2012.

Teams.txt--This file contains a list of several Major League baseball teams in alphabetical order. Each team listed in the file has won the World Series at least once.

WorldSeriesWinners.txt - This file contains a chronological list of the World Series' winning teams from 1903 through 2012. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2012. Note that the World Series was not played in 1904 or 1994.)

Hint: Read the contents of the WorldSeriesWinners.text file into a List. When the user selects a team in the ListBox, the application should display the number of times the selected team appears.

Java program code: InventoryManager

For this assignment, you will be creating an inventory manager for a store that sells vegetables. The inventory will be managed using arrays.

The required name for the project is InventoryManager.
The required name for the Java file is InventoryManager.java.
The required main class name is InventoryManager.

Part 1: Planning the store

Decide the name of your store. Place this name in a constant called STORE_NAME.
As soon as the program starts, display a greeting to the user to let them that they have begun using the inventory management app for this store.
Then, perform the following:

1. Create an array called items for a maximum of 5 items in your store. The items in the array should be onion, broccoli, carrot, zucchini, and cucumber.
2. Create a second array called quantities to store the quantity of each of the five items.
   Using a loop, have the user enter the quantity of each of the five items, and make sure each value of quantity is inserted into quantities array at the appropriate index (the same index as the item in the items array).
   For this step, we will assume the user will only enter an integer, but you should validate their input to make sure they enter a value greater than or equal to zero. If they do not enter an integer greater than or equal to zero, then you must prompt them to enter the value again (until they get it right).
   HINT: Consider using another loop to have them enter the quantities.
3. Create a third array called prices to store the price of each of the five items. Using a similar process to Step 2, have the user enter the price of each of the five items and make sure they are stored in the prices array at the appropriate index. Just like Step 2, you should make sure the user-entered prices are greater than or equal to 0. Otherwise, they should repeat entering the value until they get it correct.

The following table is just one example of the values that might populate the three arrays. Each index represents one single item.

NOTE: Apart from the items array, these are just example values. Because the user is required to enter these values, values in quantities and prices could be anything.

If we were to determine the quantity of our carrots, we would first find that "carrot" is located at index 2 in items, so we would retrieve the value in quantities at index 2, which is a quantity of 3. To find the price, we would retrieve the value at index 2 of prices, which is 1.25.

Make sure you use the appropriate datatype for each array (int? double? String?)

All of the previous directions take place only at the beginning of the program. You can think of it as the set up for the main part of the program. Once done, the user will be taken into Part 2 of this assignment.

Part 2: Operating the InventoryManager

Display to the user the possible operations on the inventory and prompt him/her to choose one. The user should select the option by entering its number. Every time the user completes one of the operations (except for Exit), the user should be taken back to this screen where they can choose from this list again. If Exit is selected, the user should be given a message thanking them for using the program, and then the program should be properly closed. Do not use System.exit() to close the program. You must exit the program by exiting the loop itself.

There are 5 possible operations:

1. Print inventory
2. Check for low inventory
3. Highest and lowest inventory value items
4. Total inventory value
5. Exit

1. Print inventory

This operation prints all the inventory items, with each item shown in the following format:

Item: ITEM-NAME
Quantity: ITEM-QUANTITY
Price: ITEM-PRICE
Total value: TOTAL-VALUE

ITEM-NAME should be replaced by the name of the item.
ITEM-PRICE should be replaced by the price of the item.
TOTAL-VALUE should be replaced by the total price if someone were to purchase the entire stock of items.

Make sure your output appears exactly like the format above. You should print the information for all five items in an efficient way (using a loop).

Once this is done, the user should be allowed to select one of the five options from the original menu.

2. Check for low inventory

This operation checks for items that have a quantity of less than 5, then prints them in the same format as in option 1.

If there is no such item whose quantity is less than 5, then display a message that explains that to the user.

Once this is done, the user should be allowed to select one of the five options from the original menu.

3. Highest and lowest inventory value items

This operation finds the following two items:

• The item with the highest inventory value.
• The item with the lowest inventory value.

Remember that the total inventory value is the value of the whole stock of the inventory item combined, which would be equal to the quantity multiplied by the price.

If two or more items have a matching inventory value and they are either the highest or lowest, then you only need to display one of them.

Display the highest and lowest inventory value items in the same way as option 1.

Once this is done, the user should be allowed to select one of the five options from the original menu.

4. Total inventory value

This is the total value of ALL items in the store, taking into account the quantity of each item. Display this value to the user.

Once this is done, the user should be allowed to select one of the five options from the original menu.

5. Exit

If selected, the user should be given a message thanking them for using the program, and then the program should exit. Do not use System.exit() to exit the program. You must exit the program by logically ending the loop.

Requirements

When this program runs, it should be obvious to the user the values they are seeing. Include all units when displaying values. For example, when displaying dollar values, make sure you include a dollar sign ($). You do not need to worry about making two decimal digits show when displaying dollar values. For example, it's okay to display $4.5 instead of $4.50.
