Re: [OT] C help plz..

One could easily expand the code snippet to something more like...

int i;
char c;
unsigned long l;
:
:
for (i = sizeof(unsigned long); i > 0; i--)
{
    int shift_factor = (i - 1) * 8;
    c = (char)((l & ((unsigned long)0xFF << shift_factor)) >>
shift_factor);
    putchar(c);
}

... if you want to be pedantic about the size of an unsigned long.
