  Have you tried these. Post whatever you did here, so that you may analyze where you went wrong, and, we know that you had worked hard and are not one of the free lunch seekers.

  @abbd: I checked your previous posts. It seems everywhere you have asked questions which I feel are all related to your assignments or something. You are getting your college work done from us without giving it a shot. You have got your answers previously from some of our members but not this time. Your bad luck dude, you met me first, not some soft hearted person.
  Do as I told you in my post above and then you can expect help this time.
  
  P.S. All free codes will be deleted

  int main(void)
  {
  int n ;
  scanf("%d",&n) ;
  printf ("the area is %7.4f\n", area (0.0 , 3.0 , n)) ;
  return 0 ;
  }
  double f(double x)
  {
  return ((3*x*x)+(2*x)+5) ;
  }
  double area (double a,double b,int n)
  {
  double width = (b-a)/n ;
  double sum =(f(a) + f(b)) / 3.0 ;
  double xvalue ;
  for(xvalue = a+width ; xvalue < b;xvalue+=width )
  sum+=f(xvalue) ;
  return ( sum* width ) ;
  }

  abbd1990, post the code of your other problems (even if they are non-working). That will help us in identifying where you are stuck.
