No - the full 32-bit representation of 0xAB78 is: 0000 0000 0000 0000 1010 1011 0111 1000 The leftmost bit is zero. > Note size of int and long int are the same both are 4 bytes long > > Is this to be expected? I think so. I've not yet struck a case on Windows where either int or long are not 4 bytes. (Haven't tried Cygwin64.) Certainly, on some other systems, int is 4 bytes and long is 8 bytes. The standards permit both configurations.
