multimap 求纠错

#include <iostream>
#include <map>
using namespace std;
int main()
{    multimap<string,int>mymap;
      multimap<string,int>::iterator iter;
 pair<multimap<char,int>::iterator, multimap<char,int>::iterator> par;
mymap.insert(pair<char,int>('a',8));
mymap.insert(pair<char,int>('b',10));
mymap.insert(pair<char,int>('b',990));
mymap.insert(pair<char,int>('c',69));
mymap.insert(pair<char,int>('d',89));
mymap.insert(pair<char,int>('d',39));
mymap.insert(pair<char,int>('e',89));
mymap.insert(pair<char,int>('f',1));


cout<<"the map contains"<<endl;
for(char ch='a';ch<='f';ch++)
{
cout << ch << " =>";
    par = mymap.equal_range(ch);
    for (iter=par.first; iter!=par.second; ++iter)
      cout << " " << (*iter).second;
    cout << " "<<endl;
    }
system("pause");
  return 0;

}

错误在
par = mymap.equal_range(ch);
for (iter=par.first; iter!=par.second; ++iter)
cout << " " << (*iter).second;
cout << " "<<endl;
}

[解决办法]
multimap<string,int>mymap;和pair<char,int>的key value不一致
[解决办法]
par = mymap.equal_range(ch)
