c、c#---计时器

c计时器
用法1：

#include "time.h"clock_t start, finish;start = clock();... ...finish = clock();double duration = (double) (finish-start)/CLOCKS_PER_SEC;   //时间以秒为单位

用法2：

#include "time.h"... ...cout << "Time used = " << (double)clock()/CLOCKS_PER_SEC << "s\n";  //时间以秒为单位

c#计时器

System.Diagnostics.Stopwatch Time = new System.Diagnostics.Stopwatch();Time.Start();    ... ...Time.Stop();Console.WriteLine("用时1：{0}", Time.Elapsed.TotalSeconds);Time.Restart();   //继续计时Console.WriteLine("用时1、2：{0}", Time.Elapsed.TotalSeconds);Time.Reset();     //重置Time.Start(); ... ...Console.WriteLine("用时3：{0}", Time.Elapsed.TotalSeconds);
