Q # 3.
Illustrate your knowledge of C Programming by implementing a Bank ATM Machine as a C-
Program. Program will first ask the user for a 4-digit passcode. If the user enters wrong
passcode, program will exit. If the user enters the correct passcode, program will display the
following menu on screen and ask the user for choice using Switch’ statement.
• Withdraw Cash
• Check Account Balance
• Pay the Utility Bill
Three user defined functions will be implemented to handle each choice.
Function Withdraw.Cash 0′ will ask the user to enter the amount. Function will deduct the
amount from the balance. Function will also deduct transaction charges of Rs. 25. If amount
withdrawn is more than the account balance, function will display message ‘Insufficient
Balance’. After the transaction, function will display the amount withdrawn and the remaining
balance on the screen.
Function CheckBalance) will display the current account balance on the screen.
Function PayUtilityBill ) will ask the user to enter Bill amount. Function will check, if there
is sufficient balance in the account to pay the bill. If yes, function will deduct the bill amount
from the account balance. Function will also deduct service charges of Rs. 45. Function will
show the paid bill and the remaining balance on the screen.
Account balance will be passed as input argument to all the functions. Return type of all the
functions will be ‘void’. Next, program will ask the user if he wants to make another transaction
or not. If the user enters ‘y’ or ‘Y’, whole process will repeat. Otherwise program will end.
Program should start with an initial account balance of Rs. 200,000. (Hint: You may define user
passcode as a character type constant).
