Thread: Need help to get rid of segmentation fault

Hi everyone in the forum. I was just wondering if anyone in this forum could help me get rid of segmentation fault in my programme. The code of the programme is below"

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
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 ;
public:
	RedwoodBayDataList()  {FileName = "RedwoodBaySeismicEventList.Data";}


    
    void PostSeismicInfo();
    void WeeklyReport();
};








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


void RedwoodBayDataList::PostSeismicInfo()
{
	int K;
	string Line, ID, Date, Hour;
	double Magnitude;
    fstream InFile("RedwoodBaySeismicEventList.data", ios::in);
	//...then get the values for each location...
	RedwoodBaySeismicData Buffer;




	for(K = 0 ; K < 42 ; K++)  {
          
        getline(InFile, Line);
		ID = Line.substr(0,4);
		Date =  Line.substr(6,7);
		Hour = Line.substr(9,3);
		Magnitude = atof(strtok((char*)Line.c_str(), " ") );
		 
		
        
        Buffer.SetID(ID);    //Use these values to load the Buffer record...
		Buffer.SetDate(Date);	
		Buffer.SetTime(Hour);
     	Buffer.SetSeismicSize(Magnitude);
        RedwoodBayDataSpots.push_back(Buffer);


		RedwoodBayDataSpots[K].SetID(ID);
		RedwoodBayDataSpots[K].SetDate(Date);
		RedwoodBayDataSpots[K].SetTime(Hour);
		RedwoodBayDataSpots[K].SetSeismicSize(Magnitude);


	cin.ignore(100,'\n');  //This flushes the input buffer of any extra characters.


}


}
//This produces the final product...the report on Seismic Activiies.....


void RedwoodBayDataList::WeeklyReport()
{
	int Count;


    cout << "\n\t=============================================================" << endl;  //This section is the report...it's really all about the formatting...
    cout << "\tWeekly Report" << endl;
    cout << "\t===============================================================" << endl;
	cout << "\tLocation\tDate\tHour\tMagnitude" << endl;
    cout << "\t===============================================================" << endl;
	for(Count = 0 ; Count < 42 ; Count++) 
		cout << "\t" << RedwoodBayDataSpots[Count].GetID() << "\t" << RedwoodBayDataSpots[Count].GetDate() << "\t" << RedwoodBayDataSpots[Count].GetTime() << "\t"  << RedwoodBayDataSpots[Count].GetSeismicSize();
        cout << "\t===============================================================\n\n" << endl;
}


//Declare the functions...


void RunIT();
void Menu();




int main()
{
	RunIT();
}


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


void RunIT()
{
	RedwoodBayDataList RedwoodBayDataSpots;
	string Command = "";


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


		
	    if(Command == "Report")
			RedwoodBayDataSpots.WeeklyReport();
	}
}


//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 help or suggestions will be greatly appreciated.
