Just like with the left shift operator, the bit pattern changes its size after a right shift. While moving bits to the right makes the binary sequence shorter, it usually won’t matter because you can put as many zeros in front of a bit sequence as you like without changing the value....

2) A small, somewhat quibbling thought, for C++ users this would seem like an appropriate place to use an iostreams style bit shift operator overload... perhaps less confusing to leave the code as is, but unlike the addition operator, the bitshift operator makes it visually clearer (for ...
