使用boost庫處理 int 、float、string之間相互轉換

我在網上找了一個別人已經編譯好的boost

開啟vs2013 ，新建一個c++控制檯工程：

#include "stdafx.h"

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


using namespace std;
using boost::lexical_cast;

int main()

{

    int a = lexical_cast<int>("123");

    double b = lexical_cast<double>("4.6987");

    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;

    }
    system("pause");
    return 0;

}

編譯後的結果如下：
