ATM need help

#include < stdio.h >

  void main ()

  {

  int w;

  float b;

scanf("%d %f",&w,&b);

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

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

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

whats wrong in this?

There are a few things you have to follow when submitting code to an online jusge:

  1. Always declare your main as int main and not void main

  2. Return a 0 at the end of main i.e. return 0;

  3. Generally print each answer on a new line i.e. add a ā€œ\nā€ after printf

Also in your condition, it should be b - 0.5 >= w as the balance can be zero after the transcation.

also make sure that they cant give a negative withdrawl
for example w = -120

Sorry?

Positive integer 0 < X <= 2000 - the amount of cash which Pooja wishes to withdraw.
