Hi again and thank you all.

Here is what I tried. Since I have two numbers and better than speculating which is which, I tried this:

Code:

#include <iostream>
 
int main()
{
  std::cout << "Please specify two natural numbers:" << std::endl;
  int i, j, k;
  std::cin >> i >> j;
 
  if (i >= j)
    {
      k = j;
      j = i;
      i = k; 
     }
 
      for (int x = i; x <= j; ++x) std::cout << x << " ";
 
      std::cout << std::endl;
 
  return 0;
}

Still, I do not know why my second posted code (the one with if ( i==j ) ) doesn't work?
No matter what the two numbers are, it prints the message that the two numbers are equal!
