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
