stopwatch_constructor.cpp

Initializes a xtd::diagnostics::stopwatch instance by using a simple class constructor.

#include <xtd/diagnostics/stopwatch>
#include <xtd/threading/thread>
#include <xtd/console>
#include <chrono>
 
using namespace std::chrono;
using namespace xtd;
using namespace xtd::threading;
 
auto main() -> int {
  auto stopwatch = xtd::diagnostics::stopwatch {};
  stopwatch.start();
  thread::sleep(10000_ms);
  stopwatch.stop();
  // Get the elapsed time as a duration value.
  auto ts = stopwatch.elapsed();
  
  // Format and display the duration value.
  auto elapsed_time = string::format("{0:H}:{0:M}:{0:S}.{1:D2}", ts, ts.milliseconds() / 10);
  console::write_line("RunTime " + elapsed_time);
}
 
// This code produces the following output :
//
// RunTime 00:00:10.00
