计时器的time_t和clock_t 的两种实现方法(推荐)

#include <stdlib.h>
#include <iostream>
#include <time.h>
#include "StateFunctions.h"

using namespace std;

int main(int argc, char** argv)
{
  time_t start, finish;

  time(&start);

  StateFunctions testobj(22, 22);
  testobj.TEST();
  testobj.TEST();
  testobj.FillRandomDets(200);
  testobj.evolute(1000, 0.9);

  cout << "--------------------------------------------" << endl;
  time(&finish);
  double duration = difftime(finish, start);
  cout << "--> time: " << duration << " s" << endl;
  cout << "--------------------------------------------" << endl;

  return 0;
}

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

using namespace std;

int main(int argc, char** argv)
{
	clock_t start, finish;
	start = clock();

	StateFunctions testobj(22, 22);
	testobj.TEST();
	testobj.TEST();
	testobj.FillRandomDets(200);
	testobj.evolute(1000, 0.9);

	cout << "--------------------------------------------" << endl;
	finish = clock();
	double duration = (double)(finish - start) / CLOCKS_PER_SEC;
	cout << "--> time: " << duration << " s" << endl;
	cout << "--------------------------------------------" << endl;

	return 0;
}
