为啥vc 6.0 使用#include <map>时候编译不了？
#include <map>
//#pragma warning (disable:4786) )//加入这个也不行，不加也不行
#include <string>
#include <iostream>
using namespace std;

int main()

{

map<int, string> mapstudent;

mapstudent.insert(pair<int, string>(1, “student_one”));

mapstudent.insert(pair<int, string>(2, “student_two”));

mapstudent.insert(pair<int, string>(3, “student_three”));

map<int, string>::iterator iter;

for(iter = mapstudent.begin(); iter != mapstudent.end(); iter++)

{

Cout<<iter->first<<” ”<<iter->second<<end;

}

}

[解决办法]
vc6 对模板支持不好。换高级版本吧
