...erstand your second sentence. TDD drives better code. Your code changes in order to be testable (because testable code is necessarily modular with well-thought-out interfaces), but the primary purpose is to have better code--having automated tests is just an awesome secondary benefit. If your concer...

In total we're looking at 2128 bytes for the 1000 numbers, or 17.017 bits per 10-digit telephone number.

Now, you are most probably working on a little-endian machine and BitConverter.GetBytes() will give you the byte[] reversed. So you could try:
int intValue;
byte[] intBytes = BitConverter.GetByt...
Is it better to use std::memcpy() or std::copy() in terms to performance?
... allowed to lie within the output range. This is a little odd, because the order of assignments is defined, and a call might be UB even though the effect of those assignments, in that order, is defined. But I suppose the restriction allows vectorization optimizations.
