cant understand why it is showing wrong answer

int main()
using namespace std;

int wdraw;
float bal;
float left;
cin >> wdraw;
cin >> bal;

if(wdraw <= bal)
        left = bal-wdraw-0.50;
        cout << fixed << setprecision(2) << showpoint << left << endl;

        cout << fixed << setprecision(2) << showpoint << bal << endl;

        cout << fixed << setprecision(2) << showpoint << bal << endl;
return 0;


this is the ATM question in the easy section of the practice problems.
on submitting ,it shows Wrong Answer.
I have tried every possible input and it is giving me the correct answer on my compiler.

please help.

Check for this input

30 30.00

Output should be


but ur output is -0.50 for this problem
Thats why it is being evaluated as WA.

The total balance initially should be greater than the withdrwal balance + the tax (0.50)

so condition should be Y > = x+0.50

@gauravagarwal :

your condition should be (wdraw+0.5)<=bal , otherwise the output of the program will be -0.5 in cases where withdraw is equal to balance.
