Web1) Returns the length of the given null-terminated byte string, that is, the number of characters in a character array whose first element is pointed to by str up to and not including the first null character. The behavior is undefined if str is not a pointer to a null-terminated byte string. while (*p2++ = *p1++); is equivalent to strcpy (p2, p1); p1 += strlen (p1) + 1; p2 += strlen (p2) + 1; In other words, it copies a null-terminated string, with p1 ending up pointing to the end of the source string and p2 pointing to the end of the destination string.
