Any help with this Program ..

Hi there ..

I wanna write a program that reads two numbers ( First & Last )
& Print the numbers between them & the sum ...

This is the code ..

Code:

---

#include <iostream>
#include <conio>

int main ()
{
  int First , Last , sum = 0;
  cout<< "Enter the First number : ";
  cin>> First;
  cout<< "Enter the Last number : ";
  cin>> Last;

  cout<< "\nThe numbers between " << First << " and " << Last << " are :";
  cout<< "\n----------------------------------" << endl;

  while ( First <= Last )
  {
      cout<< First << endl;
      First++;
      sum+=First ;
  }
  while ( First >= Last )
  {
      cout<< Last << endl;
      Last++ ;
      sum+=Last;
  }
  cout<< "----------------------------------" << endl;
  cout<< "The sum = " << sum ;
  getch ();
  return 0 ;
}

---

There is no proplems when ( First >= Last ) ..
But there is when ( First <= Last ) ..

Also when I enter (-First & -Last ) or (+First & -Last) or ( -First & +Last)
.. The sum is wrong ..

& How can I solve the problem when ( First = Last)..

Any Help Greatly Appreciated..

Use an if statement perhaps?

ok I'll try ...
