实战准标准库Boost —— （2）测试Boost配置的Hello World程序

1. 配置环境

请先按照《Boost C++ Libs —— （1）配置Boost的VS2008开发环境》一文在Visual Studio中配置开发环境。

2. 源码

#include <boost/lexical_cast.hpp>
#include <iostream>

using namespace std;

int main()
{
using boost::lexical_cast;

int a=lexical_cast<int>("123");
double b=lexical_cast<double>("123.0123456789");
string s0=lexical_cast<string>(a);
string s1=lexical_cast<string>(b);
cout<<"number: "<<a<<"  "<<b<<endl;
cout<<"string: "<<s0<<"  "<<s1<<endl;
int c=0;
try{
c=lexical_cast<int>("abcd");
}
catch(boost::bad_lexical_cast& e){
cout<<e.what()<<endl;
}

return 0;
}

$(document).ready(function(){dp.SyntaxHighlighter.HighlightAll('code');});
