HELP CREATING LINKED LIST OF VECTORS

[drogbatorres]

Hi, I am trying to create a linked list of vector in my program. And, obviously, it is not working. The program is now suffering from segmentation fault. And, by the way, I know that I could write this program without using linked list; however, as a part of my assignment, I must make a use of linked list. Here is the code for the program:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <sstream>
using namespace std;

//Define a class to represent each Seismic Activity measurement event...

class RedwoodBaySeismicData
{
    string LocationID; //This is the station that owns this piece of data…
    string Date; //The date that the values were collected…
    string Time; //The time of day that the values were collected…
    double SeismicSize; //Magnitude of Earthquake


  public:
    RedwoodBaySeismicData();
    RedwoodBaySeismicData(string, string, string, double);

    //The first group of member functions are used to change values...
    //Functions are defined in the form of inlines.

    void SetID(string ID)
    {
        LocationID = ID;
    }
    void SetDate(string Day)
    {
        Date = Day;
    }
    void SetTime(string Hour)
    {
        Time = Hour;
    }
    void SetSeismicSize(double Magnitude)
    {
        SeismicSize = Magnitude;
    }


    //The second group allows controlled access to individual value in the class...

    string GetID()
    {
        return LocationID;
    }
    string GetDate()
    {
        return Date;
    }
    string GetTime()
    {
        return Time;
    }
    double GetSeismicSize()
    {
        return SeismicSize;
    }



};



//The default constructor sets the private variable members to a harmless value...

RedwoodBaySeismicData::RedwoodBaySeismicData()
{
  LocationID;
  Date;
  Time;
  SeismicSize = 0.0;

}

//This initializing  constructor allows you to create a object with value already set...

RedwoodBaySeismicData::RedwoodBaySeismicData(string ID, string Day, string Hour,
  double Magnitude)
{
  LocationID = ID;
  Date = Day;
  Time = Hour;
  SeismicSize = Magnitude;

}

class RedwoodBayDataList
{
    vector < RedwoodBaySeismicData * > RedwoodBayDataSpots; 
      //Create a collection of location information...
    string FileName;
    int K;
  public:

    // void GiveRedwoodSeismicData(RedwoodBaySeismicData *X) {RedwoodBayDataSpots.push_back(X);}
    RedwoodBayDataList()
    {
        FileName = "RedwoodBaySeismicEventList.data";
        K = RedwoodBayDataSpots.size();
    }
    RedwoodBayDataList(RedwoodBaySeismicData);

    void DisplaySeismicInfo();
    void DisplayInfoForEachStation(int);
    void DisplayAlphaInfo(int)
    {

        DisplayInfoForEachStation(K);
    }
    void DisplayBetaInfo(int)
    {
        DisplayInfoForEachStation(K);
    }
    void DisplayGammaInfo(int)
    {
        DisplayInfoForEachStation(K);
    }
    void DisplayDeltaInfo(int)
    {
        DisplayInfoForEachStation(K);
    }
    void DisplayEpsilonInfo(int)
    {
        DisplayInfoForEachStation(K);
    }

};



//Allow the user to post the values for each location...

void RedwoodBayDataList::DisplaySeismicInfo()
{





  string Line, ID, Date, Hour;
  double Magnitude;

  fstream InFile("RedwoodBaySeismicEventList.data.txt", ios::in);


  string Command2;

  {
    cout << "Choices...................................................." <<
      endl;
    cout << "-----------------------------------------------------------" <<

    Magnitude);


  cout << "\n\t============================================================="

  while (getline(InFile, Line))

    Buffer->SetID(ID);

    Buffer->SetSeismicSize(Magnitude);
    RedwoodBayDataSpots.push_back(Buffer);





    if (RedwoodBayDataSpots.size() == 114)
      break;



  }
  InFile.close();


  if (Command2 == "Alpha")
  {
    for (K = 0; K < 23; K++)

    {
      DisplayAlphaInfo(K);
    }


  }


  else if (Command2 == "Beta")
  {
    for (K = 23; K < 47; K++)
      DisplayBetaInfo(K);
  }
  else if (Command2 == "Gamma")

  {
    for (K = 47; K < 70; K++)
      DisplayGammaInfo(K);
  }
  else if (Command2 == "Delta")

  {
    for (K = 70; K < 93; K++)
      DisplayDeltaInfo(K);
  }
  else if (Command2 == "Epsilon")

  {
    for (K = 93; K < 115; K++)
      DisplayEpsilonInfo(K);

  }







  cout << 
    "\t===============================================================\n\n" <<
    endl;
}


void RedwoodBayDataList::DisplayInfoForEachStation(int K)
{
  RedwoodBaySeismicData *Buffer;
  cout << "\t" << Buffer->GetID() << "\t\t" << Buffer->GetDate() << "\t" <<
    Buffer->GetTime() << "\t" << Buffer->GetSeismicSize() << endl;




}


//Declare the functions...

void RunIT();
void Menu();
void ChooseTheStation();


int main()
{
  RunIT();
  system("pause");
}

//This function implements a simple command processor...

void RunIT()
{

  string Command1;
  int K;

  while (Command1 != "Quit")
  {
    Menu();
    cout << "Command: ";
    getline(cin, Command1);

    if (Command1 == "Report")
      RedwoodBayDataSpots.DisplaySeismicInfo();
  }
}

//This function tells the user what he or she can do...

void Menu()
{
  cout << "Choices...................................................." << endl;
  cout << "-----------------------------------------------------------" << endl;
  cout << "\tReport...displays the  report." << endl;
  cout << "\tQuit.....exits the program." << endl;
  cout << "-----------------------------------------------------------" << endl;
}

Any suggestions would be greatly appreciated.

Your post contains three occurrences of the word "list", and somehow none appear in the source code. So I'm confused.

#include <list>

std::list<std::vector<RedwoodBaySeismicData> > listOfVectors;
