Javier Gutiérrez Chamorro (Guti) in  Bitácora de Guti writes that after his article  Bucles invertidos  (Invested loops) he was surprised to see that the Visual C++ v 7.1 (2003) optimizer converts the code:

    unsigned int I;

    for (I=0; I<100; i++)

    {
    }

into "nothing". Even more surprising is that it converts:

    unsigned int i;
    for (i=0; i<100; i++)
    {
    }
    return(i);

into

    mov     eax, 100
    ret

which is the equivalent in C++ of:

      return(100);

So the optimizer has detected code that is poorly written and corrected it. We should see the new class of compilers that are coming on the market, such as GCC 4 , Visual C++ 2005 , and Intel C++ 9 being even more intelligent..
