A simple benchmark timer in C++11

I just wrote a small time-measurement-class in C++11 to be able to measure the time spended in a loop. It is just a simple struct which will measure the time via RAII ( see Resource_acquisition_is_initialization ) . The time will be measured by using the std::clock() ( see std::clock-doc ) class. So this solution will work on all platforms which are supported by a c++11-compliant compiler like g++, clang or the Visual-Studio.

You can use it as follow:

#include <ctime>
#include <iostream>
#include <string>

struct Timer {
  std::clock tick;
  std::string mName;

  Timer( const std::string &amp;name ) 
  : mName( name ) {
    tick = clock();
  }

  ~Timer() {
    clock_t end = clock();
    double elapsed_secs = double(end - tick) / CLOCKS_PER_SEC;
    std::cout << "Timer " << mName << ", elapsed time " <<; elapsed_secs << "\n";
  }
};

int main(int argc, char *argv[]) {
  int val(0);
  {
    Timer myTimer("Test 1");
    for (int i = 0; i &lt; 10; ++i) {
      Timer myTimer("Test 1.1");
      for (int j = 0; i &lt; 1000000; ++i) {
        val += i;
      }
    }
  }

  {
    Timer myTimer("Test 2");
    for (int i = 0; i &lt; 10; ++i) {
      val += i;
    }
  }

  return 0;
}

The output for this program will be ( using VC2017, Windows 10 using the Cmder terminal ):

C:\projects\TimerTest\Debug
λ .\TimerTest.exe
Timer Test 1.1, elapsed time 0.002
Timer Test 1, elapsed time 0.009
Timer Test 2, elapsed time 0

If you want to measure how much time will be spend in one loop just put the timer inside the loop and give it a meaningful name.
