How to get current time in milliseconds?

Simply use std::chrono. The general example below times the task “of printing 1000 stars”: Instead of printing the stars, you will place your sorting algorithm there and time measure it. Do not forget to enable the optimization flags for your compiler, if you intend to do some benchmarking, e.g. for g++, you need -O3. This is serious, check … Read more

You might try to insert std::this_thread::sleep_for calls to check what timing resolution fits for your needs with the hardware and OS you have at hand.
