What alterations must I do to this code.. I am receiving a Wrong answer message

All submissions for this problem are available.

Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja's account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US. Calculate Pooja's account balance after an attempted transaction. Input

Positive integer 0 < X <= 2000 - the amount of cash which Pooja wishes to withdraw. Nonnegative number 0<= Y <= 2000 with two digits of precision - Pooja's initial account balance. Output

Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance.

• Example - Successful Transaction

Input: 30 120.00

Output: 89.50

• Example - Incorrect Withdrawal Amount (not multiple of 5)

Input: 42 120.00

Output: 120.00

• Example - Insufficient Funds

Input: 300 120.00

Output: 120.00

    if (X > 0 && X <= 2000 && Y >= 0 && Y <= 2000)
    {
        if (X > Y || ((Y-0.5-X)<0))

            return 0;

        }
        if ((int)X % 5 == 0)
        {
            new_balance = (Y - X) - bank_charge;
            printf("%0.2f", new_balance);
            return 0;

        }
        printf("%0.2f", Y);
            }
