i used code measure runtime of program this answer auto start = std::chrono::system_clock::now(); /* work */ auto end = std::chrono::system_clock::now(); auto elapsed = end - start; std::cout << elapsed.count() << '\n'; i needed measure runtime trend kind of curious unit is. you can check self, code: using clock = std::chrono::system_clock; using duration = clock::duration; std::cout << duration::period::num << " , " << duration::period::den << '\n'; on system prints: 1 , 1000000000 that is, period in terms of nanoseconds (i.e. 10 −9 s).
