Lists and Seg fault

[Samariyu]

Hi, I know this is a little vague, but I keep getting a seg fault in my code every time it runs. I am trying to make a hash table that is an array of lists. right now I am focusing on the method that inserts an item into the hash table. I have tried different things, and I have no idea what's wrong. My best guess is that for some reason, the size of my list is null? Maybe? Anyway, here is my

here is the h file for hash table

  #ifndef HASHTABLE_H
#define	HASHTABLE_H
#include <list>
#include <iostream>
#include <string.h>
using namespace std;

class HashTable {

public:
	HashTable();
	HashTable(int size);
	~HashTable();
	void setHash(bool whichHash);
	void insert(string name);
	void delName(string name);
	bool search(string name);
	void logFile();
	long hashFunction(string name);
	unsigned long hash(string name);
	unsigned long sdbm(string name);
private:
	int size;
	int numEntries;
	int numFull;
	double loadfactor;//num entries divided by num of buckets(index) i.e. 80 entries/ a table size of 10 = 8
	list<string> *l;
	bool whichHash;

};
#endif 

Here is the HashTable.cpp file (the search and delete methods aren't shown. I am just focusing on the insert method). The program is breaking on the statement that reads "if(l[bucket].empty())"

#include "HashTable.h"
#include <iostream>
#include <list>
#include <sstream>
#include <string.h>
#include <fstream>
using namespace std;



HashTable::HashTable(){}
HashTable::HashTable(int size){
	this->size = size;
	this->numEntries = 0;
	this->numFull = 0;
	this->loadfactor = 0;
	this->l = new list<string>;
}
HashTable::~HashTable()
{
	delete[] l;
}
void HashTable::insert(string name){
	unsigned long bucket = hashFunction(name);
	if(l[bucket].empty()){
		l[bucket].push_back(name);
	}else{
		for(list<string>::iterator it=l[bucket].begin(); it!=l[bucket].end(); it++){

			if(it->compare(name) == 0)
			{
				cout<<"name was found, cannot insert"<<endl;
				cout<<"bucket: "<<bucket<<" name: "<<name<<endl;
				return;
			}	
		}
		l[bucket].push_back(name);
		this->numEntries++;
	}

}
void HashTable::setHash(bool whichHash){
	this->whichHash = whichHash;
}
long HashTable::hashFunction(string name){
	unsigned long hashed;
	if(this->whichHash == true){
		hashed = hash(name);
		hashed = hashed%this->size;
		return hashed;
	}else{
		hashed = sdbm(name);
		hashed = hashed%this->size;
		return hashed;
	}
}

unsigned long HashTable::hash(string name){
	unsigned long hash = 5381;
	int c;
	for(int i = 0; i < name.length(); i++)
	{
		c = name[i];
		hash = ((hash << 5) + hash) + c; /* hash * 33 + c */
	}
	return hash;
}

unsigned long HashTable::sdbm(string name){
	unsigned long hash = 0;
	int c;
	for(int i = 0; i < name.length(); i++)
		{
			c = name[i];
			hash = c + (hash << 6) + (hash << 16) - hash;
		}
	return hash;
}

And lastly, here is my main.cpp file.

#include <fstream>
#include <string.h>
#include <sstream>
#include <iostream>
#include "HashTable.h"
using namespace std;

int main()
{
	HashTable *list = new HashTable(88799);
	cout<<"MENU"<<endl;
	cout<<"(C)reate Hash Table"<<endl;
	cout<<"(I))nsert new Entry"<<endl;
	cout<<"(D)elete Entry"<<endl;
	cout<<"(S)earch by last name"<<endl;
	cout<<"(L)ogfile"<<endl;
	cout<<"(Q)uit"<<endl;
	string line;
	bool t = true;
	while(t){
		cin >> line;
		if(line == "C" || line == "c"){
			ifstream myfile;
			string file;
			cout<<"Please enter file name: "<<endl;
			cin >>file;
				while(true){
				cout<<"If you wish to use has function H(s) = djb2(s)modM, press enter 'd'."<<endl;
				cout<<"If you wish to use has function H(s) = sdbm(s)modM, press enter 's'."<<endl;
				string which;
				cin >> which;
					if(which == "d" || which == "D"){
						list->setHash(true);
						break;
					}else if(which == "s" || which == "S"){
						list->setHash(false);
						break;
					}else{
						cout<<"bad input, try again"<<endl;
					}
				}
			myfile.open(file.c_str(), ios::in);
			string name;
			//load files
			//system("pause");
			if(myfile.good()){
				cout<<"successful"<<endl;
				while(!myfile.eof()){
					myfile >> name;
					list->insert(name);
				}
			//	system("pause");
			}else{
				cout<<"file does not exist"<<endl;
			}
		}else if(line == "I" || line == "i"){
			string name;
			cout<<"Please enter a name to be inserted:"<<endl;
			cin >> name;
			list->insert(name);
		}else if(line == "D" || line == "d"){
			string name;
			cout<<"Please enter a name to be deleted:"<<endl;
			cin >> name;
			list->delName(name);
		}else if(line == "S" || line == "s"){
			string name;
			cout<<"Please enter a name to search for:"<<endl;
			cin >> name;
			list->search(name);
		}else if(line == "L" || line == "l"){
			list->logFile();
		}else if(line == "Q" || line == "q"){
			t = false;
			list->~HashTable();
		}else{
			cout<<"Error: Invalid input. Try again."<<endl;
		}
	}
}

If someone could help me get this working, that would be awesome. THank you so much.

Nevermind, I got it to work. THank you :).
