I don't want to do this by declaring any temporary variable. This program gives segmentation fault.
struct in_addr {
uint32_t s_addr;
};
You're casting an int to a pointer. Perhaps you want this:
*(struct in_addr *)&ip
But the result is implementation-defined (for a start, there're endianness considerations).
