Hi there!

I am just starting out in c++ and so far, its going ok. I have a small problem in a simple program that is frustrating me, so I am hoping someone will point me in the right direction of where I've gone wrong.

The program basically prompts the user to input two integer values, then outputs all the odd numbers between these two integer values (and their squares), and also outputs all the even numbers between the two inputted values, along with the sum of these even numbers.

I have the program working sufficiently, so long as the first value entered by the user is smaller than the second value entered. Thats the small problem I've encountered; it should not make a difference between the size of the values entered. I think i need to change the condition in the for loop, but I've tried various conditions without success

Here is the program:

```
#include <iostream>
#include <conio.h>
#include <iomanip>
using namespace std;
int main()
{
int a,b,a1,b2,square; //declaring variables
int sum = 0;
cout << "Enter two integers: " << endl; //user inputs two integers
cin >> a >> b;
cout << "The numbers entered are: " << endl; //displays the integers listed
cout << "1. " << a << endl;
cout << "2. " << b << endl;
a1 = a;
b2 = b;
//for odd numbers
cout << "The odd numbers between " << a << " and " << b <<
", along with their squares are:" << endl;
for (a++;a < b;a++)
{
if ((a%2) !=0)
{
cout << setw(4) << a;
square = a * a; //formula for finding the square of an integer
cout << " = " << square;
} //end if
} //end for
cout << endl << endl;
//for even numbers
cout << "The even numbers between " << a1 << " and " << b2 <<
" are:" << endl;
for (a1++;a1 < b2;a1++)
{
if((a1%2) == 0)
{
cout << setw(4) << a1;
sum += a1; //formula for finding the sum of the even integers
} //end if
} //end for
cout << endl;
cout << "The total sum of all the even numbers is: " << sum;
cout << endl << endl;
getch();
return 0;
}//end main
```
