Hey guys, slightly less noob programmer here for a some more help, This week in class we were assigned to create a phonebook with a couple functions to manipulate it, but it seems I am having a couple problems.
It seems to me that I have most of the program running but I do not know how to fix the last error its giving me. It says that in transducer.h when I declare Phonebook phonebook; it says im missing a ';' before phonebook...
well anyways, here's the code
Person.h
#pragma once
#include <string>
#include "Phonebook.h"
class Person
{
public:
friend class Phonebook;
private:
int id;
std::string name;
std::string category;
std::string phoneNumber;
};

std::string show();
//string showCat(vector<Person> vPhonebook);
std::string save(std::string filename);
std::string load(std::string filename);
std::string add(std::string n, std::string c, std::string p);
//string remove();
std::string clearPhonebook(){vPhonebook.clear();return "Phone Book is cleared";}
private:
std::vector<Person> vPhonebook;
int lastPersonIDUsed;
};

Any and all help is greatly appreciated. Thanks again guys.
