I am trying to solve this problem: <a href="https://stackoverflow.com/questions/268079/search-multiple-list-for-missing-entries">Search multiple list for missing entries</a>. I used a multimap for duplication of keys. Here is my code: <pre><code>#include <iostream> #include <map> #include <list> #include <utility> using namespace std; int main(){ list<char>a; list<int> b; multimap<char,int>s; a.push_back('A'); a.push_back('B'); a.push_back('C'); b.push_back(1); b.push_back(2); b.push_back(3); s.insert(std::pair<char,int>('A',1)); s.insert(std::pair<char,int>('A',2)); s.insert(std::pair<char,int>('B',2)); s.insert(std::pair<char,int>('B',3)); s.insert(std::pair<char,int>('C',1)); s.insert(std::pair<char,int>('C',3)); list<char>::iterator it; list<int>::iterator IT; multimap<char,int>::iterator i; for (i=s.begin();i!=s.end();i++){ for (IT=b.begin();IT!=b.end();IT++){ i=s.find(*IT); if (i==s.end()){ cout<<(*i).first<< " "<<*IT<<endl; } } } return 0; } </code></pre> It compiled but after I run it it stops running abnormally. I think I am not accessing elements correctly. Please help me. EDIT: i have updated my code <pre><code>#include <iostream> #include <map> #include <list> #include <utility> using namespace std; int main(){ list<char>a; list<int> b; multimap<char,int>s; a.push_back('A'); a.push_back('B'); a.push_back('C'); b.push_back(1); b.push_back(2); b.push_back(3); s.insert(std::pair<char,int>('A',1)); s.insert(std::pair<char,int>('A',2)); s.insert(std::pair<char,int>('B',2)); s.insert(std::pair<char,int>('B',3)); s.insert(std::pair<char,int>('C',1)); s.insert(std::pair<char,int>('C',3)); list<char>::iterator it; list<int>::iterator IT; multimap<char,int>::iterator i; for (it=a.begin();it!=a.end();it++){ for (i=s.begin();i!=s.end();i++){ for (IT=b.begin();IT!=b.end();IT++){ if ((*i).first==*it && ((*i).second!=*IT)){ cout<<(*i).first<< " "<<*IT<<endl; } } } } return 0; } </code></pre> but here is too much combination then i need so what is problem?i think it should work correctly

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
