Question

关于STL Map的问题

multimap<int,string> mic;
mic.insert(make_pair(3,"cap"));
mic.insert(make_pair(0,"this"));
mic.insert(make_pair(2,"a"));
mic.insert(make_pair(1,"is"));
multimap<int,string>::iterator pos_mumap;
for (pos_mumap=mic.begin();pos_mumap!=mic.end();++pos_mumap)
{
cout<< (*pos_mumap).second;
}
请问，这段代码错哪里了？

Answer 1

#include <map>
#include <iostream>
using namespace std;
int main()
{
    multimap<int,string> mic;
    mic.insert(make_pair(3,"cap"));
    mic.insert(make_pair(0,"this"));
    mic.insert(make_pair(2,"a"));
    mic.insert(make_pair(1,"is"));
    multimap<int,string>::iterator pos_mumap;
    for (pos_mumap=mic.begin();pos_mumap!=mic.end();++pos_mumap)
    {
        cout<< (*pos_mumap).second<<" ";
    }
    return 0;
}

this is a cap

代码无明显语法逻辑问题，在gcc4.7下可以运行。

疑似环境其他因素。比如编译器、ide、路径设定等等
