Implicitly declared function error C++

Ive been having an issue running my C++ file. I keep on getting two errors: definition of implicitly declared. and member declaration not found. im using eclipse Luna and MinGW as my compiler.

**EDIT: here is the exact error:

Multiple markers at this line - Member declaration not found - definition of implicitly-declared 'InsultGenerator::InsultGenerator(const InsultGenerator&)'

Here is the C++ code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include "Insultgenerator_0hl14.h"

using namespace std;

FileException::FileException(const string& m) : message(m){}

string& FileException::what(){ return message;}

NumInsultsOutOfBounds::NumInsultsOutOfBounds(const string& m) : message(m){}

string& NumInsultsOutOfBounds::what(){ return message;}

InsultGenerator::InsultGenerator(const InsultGenerator& ) {}

void InsultGenerator::initialize() const{
int cols(0);
string x;

string filename("InsultsSource.txt");
ifstream file(filename.c_str());

if(file.fail()){
    throw FileException("File not read.");
}
 while(file >> x){

 }}

//vector<string> InsultGenerator::talkToMe() const{

  //    };//end talkToMe

  //    vector<string> InsultGenerator::generate(const int n) const{

   //   };//end generate

//int InsultGenerator::generateAndSave(const string filename, const int n)           const{

//};//end generateAndSave

Here is the header file:

#ifndef INSULTGENERATOR_0HL14_H_

using namespace std;

};

class FileException{

class NumInsultsOutOfBounds{
