C Program to Display the ATM Transaction
This C Program performs ATM transaction. The types of ATM transaction are
1) Balance/Amount checking
2) Cash withdrawal
3) Cash deposition
Problem Solution
- Firstly initialize the ATM pin and amount with some random number.
- Take the ATM pin as input.
- If the input pin is equal to the initialized pin, then do the further operations.
- Use switch statement to do the operations like Balance checking, Cash withdrawal, Cash deposition etc.
- Use while loop to terminate or restart the process.

#include <stdio.h>
unsigned long amount=1000, deposit, withdraw;
int choice, pin, k;
char transaction ='y';
void main()
{
while (pin != 1520)
{
printf("ENTER YOUR SECRET PIN NUMBER:");
scanf("%d", &pin);
if (pin != 1520)
printf("PLEASE ENTER VALID PASSWORD\n");
}
do
{
printf("********Welcome to ATM Service**************\n");
printf("1. Check Balance\n");
printf("2. Withdraw Cash\n");
printf("3. Deposit Cash\n");
printf("4. Quit\n");
printf("******************?**************************?*\n\n");
printf("Enter your choice: ");
scanf("%d", &choice);
switch (choice)
{
case 1:
printf("\n YOUR BALANCE IN Rs : %lu ", amount);
break;
case 2:
printf("\n ENTER THE AMOUNT TO WITHDRAW: ");
scanf("%lu", &withdraw);
if (withdraw % 100 != 0)
{
printf("\n PLEASE ENTER THE AMOUNT IN MULTIPLES OF 100");
}
else if (withdraw >(amount - 500))
{
printf("\n INSUFFICENT BALANCE");
}
else
{
amount = amount - withdraw;
printf("\n\n PLEASE COLLECT CASH");
printf("\n YOUR CURRENT BALANCE IS%lu", amount);
}
break;
case 3:
printf("\n ENTER THE AMOUNT TO DEPOSIT");
scanf("%lu", &deposit);
amount = amount + deposit;
printf("YOUR BALANCE IS %lu", amount);
break;
case 4:
printf("\n THANK U USING ATM");
break;
default:
printf("\n INVALID CHOICE");
}
printf("\n\n\n DO U WISH TO HAVE ANOTHER TRANSCATION?(y/n): \n");
fflush(stdin);
scanf("%c", &transaction);
if (transaction == 'n'|| transaction == 'N')
k = 1;
} while (!k);
printf("\n\n THANKS FOR USING OUT ATM SERVICE");
