The standard NULL can be defined as0 or 0L or ((void *) 0) or in some other way, meaning that it might be interpreted differently in such type-less contexts. An explicit cast will make sure that it is interpreted correctly as a pointer.
If you were casting pointers instead, though, it would take the byte at the address, which would depend on endianness. So c = (char)i assigns the least-significant byte to c, but c = *((char *)(&i)) would assign the first byte at the address of i to c, which would be the same thing on little-endian systems only.
