Description
Create an application that maintains an array of your home inventory and displays
the contents of the array in a list box. For this assignment, we will be using an
array. In later chapters, we will modify this application to use a database or an
external text file. The application should look like:
g My Home Inventory
Home Inventory
Item Description
Ist Homelnventory
Serial Number
Cost
ADD
DELETE
REFRESH
BYE
Detailed Instructions
1. Define arrays for Item Description, Serial Number, and Cost after the Public
Form Q and before any click of page load events.
2. In the Page Load Event, populate the Home Inventory List Box with the data
from the arrays using the format: "ItemDecription (SerialNumber, Cost)".
3. If the ADD button is clicked, add the Item Description, Serial Number, and
Cost to the Home Inventory List Box and to the appropriate arrays.
4. If the DELETE button is clicked, remove the item from the Home Inventory
List Box and corresponding arrays.
5. If the REFRESH…
Problem
Charge Account Validation
Create an application that reads the contents of the file into an array or a List . The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List , the program should display a message indicating the number is valid. If the number is not in the array or List , the program should display a message indicating the number is invalid.
For Visual Studio .Net 4.6.1
current solution on bartleby does not work as it does not actually use a list and does not properly retrieve the file
file is a text document with 18 7 digit numbers named ChargeAccounts.txt
Using C# in Microsoft Visual Studio Create an application that simulates a game of tic-tac-toe. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element.The number 0 represents the letter O, and the number 1 represents the letterX. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.

One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file.
