Hi, I teach a 'C' class, and in a recent assignment, a student turned in
code that looks like:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(void)
{
  char *s1 = "mom", *s2 = "dad";
  int streq(const char *s1, const char *s2);

  printf("Comparing strings %s and %s\n",s1,s2);
  printf("The result was %d\n",streq(s1,s2));
  printf("The C strcmp function returns %d\n",strcmp(s1,s2));
}

int streq(const char *s1, const char *s2)
{
  if ( !*s1 || ( *s1 != *s2 )) return *s1 - *s2;
  else streq(++s1,++s2);
}

Notice that there was no explicit return from the else branch, yet this
code worked on Borlands TC (version unknown) and gcc version 2.2.2.  Does
ANSI specify anything about this behavior? Regretably I do NOT have a
copy of the standard.
