            Bug ID: 57842
           Summary: for statement not terminating properly
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: groundup2360917182914017 at gmail dot com

In the program below.  If I enter 0 through 10 it should print
0
1
2
3
4
5
6
7
8
9
10

But it doesn't.  I think what it print is a error.
0
1
2
3
4
5
6
7
8
9
10
10
11

Source Code is
#include <iostream>

int main()
{
   int number1, number2;

   std::cout << "Enter two numbers to print the numbers between: ";

   std::cin >> number1 >> number2;

   if(number1 < number2)
   {
      for(; number1 <= number2; number1++)
      {
         std::cout << number1 << std::endl;
      }
   }

   if(number1 > number2)
   {
      for(; number2 <= number1; number2++)
      {
         std::cout << number2 << std::endl;
      }
   }

   if(number1 == number2)
   {
      std::cout << number1 << std::endl;
   }

   return 0;
}
