![Exercise 20
An ATM allows a customer to withdraw a maximum of $500 per
day. If a customer withdraws more than $300, the service charge
is 4% of the amount over $300. If the customer does not have
sufficient money in the account, the ATM informs the customer
about the insufficient funds and gives the customer the option to
withdraw the money for a service charge of $25.00. If there is no
money in the account or if the account balance is negative, the
ATM does not allow the customer to withdraw any money. If the
amount to be withdrawn is greater than $50O, the ATM informs
the customer about the maximum amount that can be withdrawn.
Write an algorithm that allows the customer to enter the amount
to be withdrawn. The algorithm then checks the total amount in
the account, dispenses the money to the customer, and debits the
account by the amount withdrawn and the service charges, if any.
Your program should output account balance before and after
withdrawal and service charges. Also save the account balance
after withdrawal in the file Ch4_Ex15_Output.txt.
Ensure the output in Ch4_Ex15_Output.txt is accurate to two
decimal places.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F05a60b4b-e282-417a-93f9-b449eb57a874%2F6406e942-18d7-4861-a40a-1c40f0b624e0%2F7p968gi_processed.png&w=3840&q=75)
