3、Boost 快速上手Demo
在指定目录(/usr/local/source_code) 创建boost 测试目录(boost_demo)。指令如下
[rootlocalhost source_code]# mkdir boost_demo
[rootlocalhost source_code]# cd boost_demo/
[rootlocalhost boost_demo]# ll
总用量 0在boost_demo 目录下创建boost 测试程序accumulators_demo.cpp。指令如下:
[rootlocalhost boost_demo]# vi accumulators_demo.cpp
编辑 accumulators_demo.cpp 文件内容如下:
#include iostream
#include boost/accumulators/accumulators.hpp
#include boost/accumulators/statistics/stats.hpp
#include boost/accumulators/statistics/mean.hpp
#include boost/accumulators/statistics/moment.hpp
using namespace boost::accumulators;int main()
{// Define an accumulator set for calculating the mean and the// 2nd moment ...accumulator_setdouble, statstag::mean, tag::moment2 acc;// push in some data ...acc(1.2);acc(2.3);acc(3.4);acc(4.5);// Display the results ...std::cout Mean: mean(acc) std::endl;std::cout Moment: moment2(acc) std::endl;return 0;
}编译accumulators_demo.cpp 文件并执行。

Boost 是一组扩展了 C 功能的库。常用的包括 1. Boost.Asio包含了一套网络和底层 I/O 编程的接口支持同步、异步操作。 2. Boost.Unordered提供了类似 C11 中的 std::unordered_map, std::unordered_set 等的无序容器。 3. Boost.Thread封装了线程相关的接口如线程类、互斥量、条件变量等。 4. Boost.Python扩展了 Python/C 的转换机制以便于在 Python 和 C之间进行进行更灵活的程序集成。 5. Boost.Smart_Ptr包含智能指针如 shared_ptrweak_ptrscoped_ptr 等用于资源管理的类。 6. Boost.Filesystem提供一套跨平台的文件系统访问方法。 7. Boost.Graph提供一套图数据结构及相关算法。 8. Boost.Regex封装了正则表达式的类。 9. Boost.Log提供一套跨平台的日志库。 10. Boost.Date_Time时间和日期库提供一种简单、易于操作的方式来处理时间和日期。
