plz help me find error in this.. why is my code not working??

#include<stdio.h>
#include<conio.h>
int main()
{
double y;
int x;
scanf("%d %f",&x,&y);
if(x>0 && y>0)
{
if((x<2000) && (y<2000))
{
if(x%5==0)
{
printf("%f",y-x-0.5);
}
}
}
getch();
return 0;
}

you’ve to put one more condition in the if loop…
y-x<0.5

moreover, this specific question has already been asked and answered here.
