which has precisely the undefined action you illustrated earlier. 
With it returning void you are forced to write something like:

   strcpy(temp, word);
   strrev(word)
   if (strcmp(word, temp)) palindrome();

but you would be better off modifying strrev to do it all in one
scan, and calling it:

   bool ispalindrome(char *word);
