Question

怎么向map<char,set<int> >插入数据？

#include<iostream>#include<map>#include<set>#include<iterator>#include<string>using namespace std;int main(){typedef map<char,set<int> > MyMap;typedef map<char,set<int> >::iterator MyMapIter;MyMap My_map;MyMapIter MyMap_iter; string TempItem("ABD");
string::iterator str;if(My_map.empty()){for(str=TempItem.begin();str!=TempItem.end();str++)
{
My_map['*str'].insert(1);
}
}for(MyMap_iter=My_map.begin();MyMap_iter!=My_map.end();MyMap_iter++){cout<<(*MyMap_iter).first<<" "<<(*MyMap_iter).second;//这地方是想输出map里的数据情况。</p><p>return 0;</p><p>}

#include<iostream>

#include<map>

#include<set>

#include<iterator>

#include<string>

using namespace std;

int main()

{

typedef map<char,set<int> > MyMap;

typedef map<char,set<int> >::iterator MyMapIter;

MyMap My_map;

MyMapIter MyMap_iter;

string TempItem("ABD");
string::iterator str;

if(My_map.empty())

{
set<int> saaa;
saaa.insert(1);
for ( int i = 0; i < TempItem.length(); i++ )
{
My_map.insert( make_pair( TempItem.at(i),saaa) );
}
}

for(MyMap_iter=My_map.begin();MyMap_iter!=My_map.end();MyMap_iter++)
{
cout<<(*MyMap_iter).first<<" "<<*((*MyMap_iter).second.begin())<<endl;//这地方是想输出map里的数据情况。
}

return 0;
