//Timer类

#include "stdafx.h"#include<boost/timer.hpp>#include<iostream>#include <windows.h>using namespace boost;using namespace std;int _tmain(int argc, _TCHAR* argv[]){timer t;//最大计数单位*scout<< "time max:"<< t.elapsed_max()/3600<< "h"<< endl;//最小计数单位*scout<< "time min:"<< t.elapsed_min()<< "s"<<endl;//从timer对象创建到这里，流逝的时间cout<< "time elapsed:"<< t.elapsed()<< "s"<<endl;Sleep(3000);cout<< "time elapsed after 3 seconds:"<< t.elapsed()<< "s"<< endl;//计时器从新开始计时t.restart();cout<< "time elapsed after restart:"<< t.elapsed()<< "s"<< endl;system("pause");return 0;}

//Progress类

#include "stdafx.h"#include <Windows.h>#include "boost/progress.hpp"using namespace boost;#include <vector>#include <fstream>using namespace std;int _tmain(int argc, _TCHAR* argv[]){//vectorg构造//vector<string> vec(100);vector<string> vec(1000000, "abc");//获取当前工作目录char strPath[MAX_PATH];memset(strPath, 0x00, MAX_PATH);GetCurrentDirectory(MAX_PATH, strPath);strcat_s(strPath, "\\progress.txt");////获取模块完整路径//GetModuleFileName(NULL, strPath, MAX_PATH);//文件操作流ofstream os(strPath);//进程显示初始化progress_display pd(vec.size());vector<string>::iterator iter;for (iter=vec.begin(); iter!=vec.end(); ++iter){//文件操作流输出os<< *iter<< endl;//计数过程中涉及到其他IO流操作，进程显示会出问题，可采取以下方案//pd.restart(vec.size());//pd += (iter - vec.begin() + 1);//进程显示计数++pd;}system("pause");return 0;}
