### C program for atm transactions

1. C code for atm transaction while currencies are 1000,500
and 100

2. ATM c program source code
3. C program for atm machine
4. C program for atm banking

#include<stdio.h>

int totalThousand =1000;
int totalFiveFundred =1000;
int totalOneHundred =1000;

int main(){

unsigned long withdrawAmount;
unsigned long totalMoney;

int thousand=0,fiveHundred=0,oneHundred=0;

printf("Enter the amount in multiple of 100: ");
scanf("%lu",&withdrawAmount);

if(withdrawAmount %100 != 0){
printf("Invalid amount;");
return 0;
}

totalMoney = totalThousand * 1000 + totalFiveFundred* 500 +  totalOneHundred*100;

if(withdrawAmount > totalMoney){
printf("Sorry,Insufficient money");
return 0;
}

thousand = withdrawAmount / 1000;
if(thousand > totalThousand)
thousand = totalThousand;
withdrawAmount = withdrawAmount - thousand * 1000;

if (withdrawAmount > 0){
fiveHundred = withdrawAmount / 500;
if(fiveHundred > totalFiveFundred)
fiveHundred = totalFiveFundred;
withdrawAmount = withdrawAmount - fiveHundred * 500;
}

if (withdrawAmount > 0)
oneHundred = withdrawAmount / 100;

printf("Total 1000 note: %d\n",thousand);
printf("Total  500 note: %d\n",fiveHundred);
printf("Total  100 note: %d\n",oneHundred);

return 0;
}

Sample output:

Enter the amount in multiple of 100: 7800
Total 1000 note: 7
Total  500 note: 1
Total  100 note: 3

int main()
{
int amt;
printf("Enter the amount to withdraw : ");
scanf("%d",&amt);
printf("\nNotes of 1000 required are %d", amt/1000);
printf("\nWhile Notes of 500 required are %d", ((amt % 1000)/500));
printf("\nAnd notes of 100 required are %d",((amt % 1000)% 500)/100);

getch();
return 0;

This Code is wrong.
If withdrawAmount = 7800,
thousand = 7.8.

Hey Dear,
How to possible????
"if thousand = 7.8 greater than totalThousand = 1000..."
IF condition not run, because 7.8 not greater than 1000
