There are lots of magic in C and C++ that most people are unaware of or told never to do. But, that magic is used often by older programmers. For example, this is perfectly valid C++ (no compiler warnings or errors even with -Wall and -Wextra) it's roots are in C: #include <iostream> #include <boost/integer.hpp> int main() { // Notice these signed types are going into unsigned types! boost::uint64_t i = -9151314442815602945; std::cout << i << std::endl; unsigned int j = -327681234; std::cout << j << std::endl; return 0; }
