ATM easy problem. whats wrong here? c++

general

#include
#include
using namespace std;

int main(){
int withdraw;
float cash;

cin >> withdraw >> cash;


if(withdraw > cash)

    cout << setprecision(2)<<showpoint << fixed << cash  << endl;
else if ((withdraw +.50)<= cash)
{

    if (withdraw % 5 == 0){
    cout << setprecision(2) << showpoint << fixed << (cash-0.50) - withdraw << endl;}
    else
    cout << setprecision(2) << showpoint << fixed << cash << endl;
}

return 0;
}

btw, those constraints given, am i supposed to place it in a if statement to check it? or the test cases here will automatically not exceed within the given constraints?

First check it there is enough balance including that 0.5 when subtracted and now check if it is a multiple of 5. Here a corresponds to your withdraw and b corresponds to your cash

if (b-0.5>=a && a%5==0)

     printf("%.2f",b-a-0.5);

else if(b-0.5>a && a%5!=0)

     printf("%.2f",b);

else

       printf("%.2f",b);
