Using c++.

The file named charge_accounts.txt contains a companys list of valid charge account numbers. Each account number is a seven-digit number, such as 5658845.

Write a program that reads the contents of the file into an array. The program should then ask the user to enter a charge account number. The program will determine whether the number entered by the user is valid by searching for it in the array of valid account numbers. If the number is in the array, the program should display a message indicating the number is valid. If the number is not in the array, the program should display a message indicating the number is invalid.

Write your program in such a way as to allow the user to repeatedly enter charge account numbers for validation until the user enters a Sentinel value, such as a negative number.
