Overloading. PLEASE HELP!!!!

[Stephanie]

Why do I get this error?
Line 12: 'Contact::Contact(std::string)' and 'Contact::Contact(std::string)' cannot be overloaded.

#include <string>
#include <vector>
using namespace std;

#ifndef _CONTACT_H_
#define _CONTACT_H_


class Contact {
public:
Contact(std::string FirstName);
Contact(std::string LastName);
std::string getFirstName() ;
std::string getLastName() ;
std::string getNickname() ;
std::string getEmail1() ;
std::string getEmail2() ;
std::string getPhone1() ;
std::string getPhone2() ;
std::string getAddress() ;
std::string getWebsite() ;
std::string getBirthday() ;
std::string getNotes() ;

private:
     std ::string firstname;
     std ::string lastname;
     std ::string nickname; 
     std ::string email1;
     std ::string email2; 
     std ::string phone1;
     std ::string phone2;
     std ::string address;

};

Because these two declarations

Contact(std::string FirstName);
Contact(std::string LastName);

declare the same function Contact( std::string ); The name of the parameter does not play any role in function declaration.

[Stephanie]

How can I fix this? This is what I do with each of them in my .cpp file:

Contact::Contact(std::string FirstName)
{
	firstname = FirstName;
}

[vlad from moscow]

Declare the construactor as

Contact::Contact( const std::string &FirstName, const std::string &LastName );

Or declare a default constructor as

Contact::Contact();
and also declare additional function as

vois setFirstName( const std::string &FirstName );
void setLastName( const std::string &LastName );

[bluecoder]

you can fix it by using

Contact( std::string Name) ;

instead of two constructor decleration

Contact(std::string FirstName);
Contact(std::string LastName);

Thanks so much. I have another question. Why do I get this error?
[Linked Error] undefined reference to 'AddressBook::AddressBook()'

This is my main.cpp:

#include <iostream> 
#include <fstream>
#include "addressbook.h"

int main(){

  ifstream inStream("input.txt");
  string line, header, token;
  vector <string> tokens;
  getline (inStream, header);
  AddressBook myAddressBook;
  while(!inStream.eof())
  {
      getline (inStream, line);
      cout << line << endl;
      int x=0, y=-1;
	while(x<line.length())
        {
              x = line.find_first_of ("\"", y+1);
	      y = line.find_first_of ("\"", x+1);
	     token = line.substr(x+1,y-x-1);
             tokens.push_back (token);
             cout << token <<endl;
       	
	}	
	
}

return 0;
}

This is addressbook.cpp:

#include "addressbook.h"
AddressBook::AddressBook(){};
void AddressBook::addContact (Contact newContact)
{
      addressbook.push_back(newContact);
}

This is addressbook.h:

#include "contacts.h"

#ifndef _ADDRESSBOOK_H_
#define _ADDRESSBOOK_H_

class AddressBook 
{
public:

AddressBook();	
void addContact (Contact newContact);
        

private:
vector<Contact> addressbook;
};
#endif 

[bluecoder]

I think you do not require semicolon after the constructor definition ends

AddressBook::AddressBook(){}

[vlad from moscow]

It looks like addressbook.cpp was not included in the project. Also remove the semicolon after closing brace in the constructor definition.

[Stephanie]

thanks so much. so now how can I create a Contact with those tokens
like Contact newContact(tokens[1], tokens[2],token[3] .... tokens[11])
each token represents one of the items. ex. first name is token[1]
and where would I include this?

[Stephanie]

So, how could I now create a Contact with these tokens?
