Charge Account Validation
In the Chap07 folder of the Student Sample Programs, you will find a file named ChargeAccounts.txt. The file contains a list of a company’s valid charge account numbers. There are a total of 18 charge account numbers in the file, and each one is a 7-digit number, such as 5658845.
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

- Write a statement that declares a procedure-level one-dimensional array named intorders. The array should contain 15 elements.arrow_forwardUsing 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.arrow_forwardAssignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the "*" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level Re-initialize the 2D array and fill every element with the "*" symbol. 2. Add Platform Prompt the user to enter a starting point and length for the horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns (or out of bounds), notify the user that this is not possible. 3. Add Item Prompt the user to enter a column and row index. Replace that element in the…arrow_forward
