how to declare a map of linked lists with stl?

[Sno Kart]

I have included a rough example for purposes of illistration.

I want to look up an item based on the key in the map and search through the linked list.....help...there is a problem with the declaration.

Thank you for your time and effort.

#include <iostream>
#include <map>
#include <list>
#include <string>
using namespace std;

class book
  {
  public:
  string author;
  long ISBN;
  float price;
  };

using namespace std;

void main() {
  book bk;
  list<book> record;
  list<book>::const_iterator iter1;
  //here is the problem.............................
  map<book,record> track;//why doesn't this work????
  //I wnat a map of linked lists....HELP!
  for(int j = 0; j < 3; j++)
    {
      cout<<"Enter author,isbn,and price"<<endl;
      cin>>bk.author;
      cin>>bk.ISBN;
      cin>>bk.price;
      record.push_back(bk);
    }
  
  
  float search;
  cout<<"Enter Price to search for"<<endl;
  cin>>search;

  for(iter1 = record.begin();iter1 != record.end(); iter1++)
    {
    if((*iter1).price == search )
      {
       cout<<bk.author<<" "<<bk.ISBN<<" "<<bk.price<<endl;
      }
    }    
  
  //this is a working portion of map example
  map<string, int> freq;
  
  string word;  
       for(int i = 0; i < 3; i++)
      {cout<<"enter words for mapping"<<endl;
        cin >> word;
        freq[word]++;
      }
    cout << "Number of words = " << freq.size() << endl;

    map<string, int>::const_iterator iter;
    for (iter=freq.begin(); iter != freq.end(); iter++) 
    {
      cout << iter->second << " " << iter->first << endl;
        if(iter->second == 4)
          {
          freq[word]--;
          cout << iter->second << " " << iter->first << endl;
          }

    }

    
}//end main

I did not look over all the code but you are trying to pass a variable ('record') as a template argument which will not work...

Typedef your containers...

class book
{
public:
  string author;
  long ISBN;
  float price;
};

typedef list<book> RECORD_TYPE;
typedef map<book, RECORD_TYPE> TRACK_TYPE;

int main()
{
  book bk;
  RECORD_TYPE record;
  RECORD_TYPE::const_iterator iter1;
  TRACK_TYPE track;

  ....

  return 0;
}

That's it! Thank you! I failed to see the forest for the trees...

Thanks again!
