Introduction

Those are the loops we used to time how much slower myodd::dynamic::Any() is compared to 'normal' multiplication.

Standard loop

#include <iostream>
#include <time.h>

int main() {
  clock_t t = clock();
  long long int i = 0;
  long long int c = 0;
  for (i = 0; i<1000000000; i++)
  {
  	c = c-1;
  }
  t = clock() - t;
  printf("It took me %d clicks (%f seconds)", t, ((float)t)/CLOCKS_PER_SEC );

  return 0;
}

myodd::dynamic::Any loop

#include <iostream>
#include <time.h>
#include "dynamic/any.h"

int main() {
  clock_t t = clock();
  long long int i = 0;
  myodd::dynamic::Any c = 0;
  for (i = 0; i<1000000000; i++)
  {
  	c = c-1;
  }
  t = clock() - t;
  printf("It took me %d clicks (%f seconds)", t, ((float)t)/CLOCKS_PER_SEC );

  return 0;
}
