Can anyone tell me what is wrong with this code?

Question. 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

My code-
#include
using namespace std;

int main() {
// your code goes here
int amount_withdraw;
double acount_balance;
cin>>amount_withdraw>>acount_balance;

if(amount_withdraw>acount_balance)
{
    printf("%.2f",acount_balance);
}
else if(amount_withdraw%5 !=0)
{
    printf("%.2f",acount_balance);
}
else if(amount_withdraw%5==0)
{
    printf("%.2f",acount_balance-amount_withdraw-0.5);
} 

return 0;

}

}
