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

- what is a feature in the Windows Server Security Compliance Toolkit, thank you.arrow_forwardYou will write a program that allows the user to keep track of college locations and details about each location. To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the programarrow_forwardShow all the workarrow_forward
