(C++) boost::timer

include <iostream>

include <boost/timer.hpp>


int main()
{
  boost::timer t;
  for (int i=0; i<10000000; ++i) std::rand();
  std::cout << t.elapsed() << std::endl;
}

Same example using the Standard library

// Note: shouldn't it be std::clock_t ?
include <iostream>

include <ctime>


int main()
{
  const clock_t begin = std::clock();
  for (int i=0; i<10000000; ++i) std::rand();
  const clock_t end = std::clock();
  std::cout << "Time of STL rand(): " << std::difftime(end,begin) << std::endl;
}
