Question

Program Challenge#1: Charge Account Validation From thebook: Write a program that lets the userenter a charge account number. The program should determine if thenumber is valid by checking for it in the following list (orderdoes not matter): 5658845, 8080152, 1005231, 4520125, 4562555,6545231, 7895122, 5552012, 3852085, 8777541, 5050552, 7576651,8451277, 7825877, 7881200, 1302850, 1250255, 4581002 The list ofnumbers above should be initialized in a single dimensional array.A simple linear search should be used to locate the number enteredby the user. If the user enters a number that is in the array, theprogram should display a message saying the number is valid. If theuser enters a number that is not in the array, the program shoulddisplay a message indicating the number is invalid. Additional notes to thebook: Use the following skeleton for themain function:

long accounts[arrSize] = { ... };

int results;

long number;

number = get_number(); // subroutine will ask user for anumber

results = searchList(accounts, arrSize, number); // subroutine willsearch number in array

if (results == -1)

cout << "The number you entered is invalid. ";

else

cout << "The number you entered is valid and found inelement " << results << " in the array." <<endl;

Note: The function searchList is basically alreadygiven to you in program 8-1. Make sure you understand what thefunction returns to 'results' and how the program uses thatinformation.
