**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

Input:

**Output:**

89.50

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

Input:

Input:

42 120.00

**Output:**

120.00

**Example - Insufficient Funds**

Input:

Input:

300 120.00

**Output**:

120.00

**My code is:**

#include <stdio.h>

int main(){

float result;

int withdraw;

float initBal;

scanf("%i%f", &withdraw,&initBal);

if( (withdraw%5==0)&&(withdraw<initBal) ){

result=initBal-(float)withdraw-(float)0.5;

printf("%.2f\n", result);

}

else if(withdraw%5!=0){

printf("%.2f\n", initBal);

}

else if( (withdraw%5==0)&&(withdraw>=initBal) ){

printf("%.2f\n", initBal);

}

return 0;

}

But it gives a wrong answer (WA). Please correct.
