1.2 boost庫學習--類型轉換（數值類型to字符串）

#include <boost/lexical_cast.hpp>
using boost::lexical_cast;

#include <iostream>
using namespace std;

int main()
{
	//int to string
	string sInt = lexical_cast<string>(123);

	//double to string
	string sDou = lexical_cast<string>(123.123);

	cout<<sInt<<endl;
	cout<<sDou<<endl;
}
