int转string的3种方法

#include <strsafe.h>
#include <sstream>
using namespace std;
using std::endl;
using std::wcout;
using std::wstring;

wstring int2string()
{
    wstring strNum;
    int nNum = 1039;
    TCHAR szNum[16] = { 0 };
    std::wcout.imbue(std::locale("chinese"));            //让wout可以输出中文;

    //方法1 _itoa_s/_itow_s法
    _itow_s(nNum, szNum, 10);
    strNum = szNum;
    wcout <<L"测试语句,方法1: " <<strNum.c_str()<< endl;


    //方法2 StringCchPrintf/sprintf法
    strNum.clear();
    StringCchPrintf(szNum, 16, _T("%d"), nNum);
    strNum = szNum;
    wcout << L"测试语句,方法2: " << strNum.c_str() << endl;

    //方法3 stringstream/wstringstream法
    strNum.clear();
    wstringstream strNum2;
    strNum2 << nNum;
    strNum2 >> strNum;
    wcout << L"测试语句,方法3: " << strNum.c_str() << endl;

    return strNum;
}
