C++疑问

#include<iostream>

#include<string>

using namespace std;

//#define aaa L"sssssssssssssssss"

//#define bbb "中国"

#define bbb L"中国"     ----->不是说加了之后是宽字符么，怎么打印出来的东西很奇怪嗯

int main()

{

int and;

//cout<<"Hello world"<<"\n";

string mystring("i am ne ");

//mystring = "This is the initial string content";

//mystring("This is a different   string content");

cout<<mystring<<"\?"<<endl;

//cout<<aaa<<endl;

cout<<bbb<<endl;
