C++一直缺乏对时间和日期的处理能力,一般借助于C的struct tm和time():timer包含三个类其中timer,progress_timer是计时器类,进度指示类是progress_display. 1.timer类,内部封装的是std::clock,精度依赖于具体的编译器和操作系统.只能计算从声明对象到对象结束的时间. #include <iostream> #include <boost/timer.hpp> using namespace std; using na
Boost.Timer provides clocks to measure code performance. At first, it may seem like this library competes with Boost.Chrono. However, while Boost.Chrono provides clocks to measure arbitrary periods, Boost.Timer measures the time it takes to execute c
