    int totalBalance = 50000;
    int depositAmount = 0;
    int withdrawAmount = 0;

    int option;

    int Atmpin = 0;

    Console.Write("Enter Your ATM Pin: ");
    Atmpin = int.Parse(Console.ReadLine());

    if (Atmpin == 1234) {

        break;
      case 2:
        Console.Write("\nEnter withdrawal amount: ");
        withdrawAmount = int.Parse(Console.ReadLine());

        if (withdrawAmount % 100 != 0) {
          Console.WriteLine("\nPlease enter withdrawal amount in multiple of 100");
        } else if (withdrawAmount > totalBalance) {
          Console.WriteLine("\nIn-sufficient balance in your account");
        } else {
          totalBalance = totalBalance - withdrawAmount;
          Console.WriteLine("\n\nPlease collect your money");
          Console.WriteLine("\nYour remaining balance is: " + totalBalance);
        }
        break;
      case 3:
        Console.Write("\nEnter amount to deposit: ");
        depositAmount = int.Parse(Console.ReadLine());
        totalBalance = totalBalance + depositAmount;
        Console.WriteLine("Your current balance: " + totalBalance);
        break;
      case 4:
        Console.WriteLine("\nInvalid Option");
        break;

Explanation

In the above program, we created a class ATMDEMO that contains the Main() method. Here we created an ATM menu that provides the following options:

1. Balance Enquiry
2. Cash Withdrawal
3. Deposit your Cash
4. Exit

Here we take user input for ATM PIN, if ATM PIN is correct then we can use the above options.

Balance Enquiry:

Here we print the total balance of the user.

Cash Withdrawal:

Here we checked entered amount that should be multiple of 100, and check entered amount must be less than total balance, if both conditions are satisfied then we can withdraw the amount from ATM.

Deposit Cash:

Here we took amount as input and add to the total balance and then print total balance on the screen.

Exit:

This option is used to exit from ATM program.
