strcmp

hi,

Stefan, I think that Affan means what does the "string1 is less than string2" means? Less in length? Less in what?

Thanks,
Oleg

"Less in length? Less in what?"

Less lexicographically.

Here's the source from a well known C library implementation:

int strcmp(char * src, char * dest)
{
   int ret = 0 ;

   while(!(ret=*(unsigned char *)src-
   *(unsigned char *)dest) && *dest)
   {
      ++src;
      ++dest;
   }

   if(ret<0)
      ret = -1 ;
   else
      if(ret>0)
         ret=1;

   return(ret);
}

Thanks,

That was exactly what I was asking. I wanted to use the return values of strcmp for sorting strings.
