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_forwardProblem 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.txtarrow_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_forward
- Assignment 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_forwardAssignment 5C: Level Map Creator.

Figure 7-49 shows an example of the application’s form. The form shown in the figure uses eight large Label controls to display the Xs and Os. 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.
