boost_1_55_0b1是纯净的源码，需要用户自己编译；
boost_1_55_0-msvc-12.0-64.exe是VS2010已编译的，含源码和编译生成的库。直接下载后者就可以
#include <iostream>
#include <stdlib.h>
#include <boost\lexical_cast.hpp>
using namespace std;
void main()
{
cout << "hello world" << endl;
int i = 8848;
char *mystr = "2013";
i = boost::lexical_cast<int>(mystr);
cout << i << endl; //2013
system("pause");
}
