Class member variables/functions

[Griffinflame21]

"Use the Employer and PersonalInfo classes as member variables of a Person class. Modify the menu interface and input algorithms to accept data for the Employer and Personal Info classes via functions in the Person class."

I have 2 questions.
1. How would I use the employer and personalinfo classes as member variables in Person class?
2. Person.h lines 23-26 and lines 28-31. Lines 23-26 I want to refer to the PersonalInfo class. Lines 28-31 I want to refer to the Employer class. But I want them both to be called through Person. Is that possible? I may (probably) be doing this wrong...

I think they mean something like this:

class Employer {
private:
    string email;
    // etc.
};

class PersonalInfo {
private:
    string firstName;
    string lastName;
    unsigned age;		// note that age is not a string
    string phoneNum;
    // etc;
};


class Person {
public:
    PersonalInfo info;
    Employer employer;
};

[Griffinflame21]

Hmm. It compiles now. But. Is there a way that I can get the constructors in Person to refer to the info in PersonalInfo and Employer?
Or is that just not possible? Because it feels like I'm not even using Employer or PersonalInfo...

Also noticed while compiling that when outputting the files, it only outputs whatever was last input....

    void Exit()
    {
        cout << "Closing...";
    };
} Recordsbook;

int main()

    Recordsbook.Menu();
}

How would I make the for loop in void Display() in main.cpp print out the whole vector?

Use the Employer and PersonalInfo classes as member variables of a Person class

I think you're missing the point of what this means. Since the PersonalInfo class has first name, last name and phone number, you don't need to duplicate those members in the Person class. The only members that seem to be needed in the person class are a PersonalInfo and an Employer. That's what I showed in my original post.

It looks like you've given part of a larger assignment. Can you post the full assignment, including whatever they say about the PersonalInfo and Employer classes? Right now you also have duplicate info in PersonalInfo and Employer.

[Griffinflame21]

"Modify the Vector address book program you created in the previous module by creating a Person Class, an Employer Class and a Personal Info Class. Use the Employer and PersonalInfo classes as member variables of a Person class. Modify the Vector class to hold People objects instead of Record objects. Modify the menu interface and input algorithms to accept data for the Employer and Personal Info classes via functions in the Person class. Modify the Output to print all the information in each Person object, associated Employer object, and associated Personal Info object. Make sure to separate the implementation of your classes from the header files. You should have a .cpp file and a .h file for each class you create."

That's the entire assignment. They don't even say what should be in employer or personalinfo.. (The Records class mentioned is very similar to my personalinfo class.) So, in Person.h, all I need is employer employer and personalinfo info and that's it? What would go in Person.cpp then..?

[longberns]

@Griffinflam21,
Yes, it seems as if you have provided more information about your problem. Without asking more question, I assume that Employer gets information from PersonalInfo (I see that the only extra stuff for Employee is email)

I made something like this

I don't know if you have covered inheritance/polymorphism. The classes could have been way simpler as dhayden pointed out.

Note: There are no checks for age! You enter something that stoi cannot convert to int will crash the program.

Hope you get a better idea now.

[Griffinflame21]

I haven't learned about inheritance or polymorphism yet. I think I'm learning about that next week..
But wow thank you! I will definitely look that over. This is my second time using the whole .h and .cpp separated files thing, let alone using functions in one that is calling info from the others...so I'm not familiar with it. Along with the assignment not specifying what is supposed to go in PersonalInfo and Employer, kind of has me really lost about how to do the whole assignment properly.

Also, stoi?

The original Record class uses record number, first name, last name, age, and telephone number. I added email in because....I don't remember why, I think I was trying to make Employer a separate type of contact from PersonalInfo.

Edit:
@blongho

Well, i am very sorry if the program doesn't compile. I am using Microsoft Visual Studio (VS) 2017 and the program compiles hitch-free. No warnings!

You might want to check if your compiler can work with C++ 11.

IMHO, i can can decipher what is wrong that you don't get the program running.

This is my second time using the whole .h and .cpp separated files thing

It is not complicated once you do it from the second time. In PersonalInfo.h
since you already have

#include <iostream>
#include <string> 

Adding #include "PersonalInfo.h" means all the includes in the .h files are "carried" there too. It is useless taking them there again.

stoi is an in-built function in C++ that converts string to interger. Read more here http://www.cplusplus.com/reference/string/stoi/

The original Record class uses record number, first name, last name, age, and telephone number.

This means the class will be something like this

#ifndef PEOPLE_H
#define PEOPLE_H
#include "Person.h"
#include <vector>

class People
{
private:
	std::vector<Person> persons;
	int count;
public:
	People() : persons{}, count{ 0 } {}
	~People() {};

	int getPeopleCount() const { return persons.size(); }

	int getCount() const {return count; }
	void addPersons();
	void showPersons();
	void menu();
};

#endif // !PEOPLE_H

//And then modify these  in People.cpp
void People::addPersons()
{
	int entries = 0;
	cout << "How many records do you want to input?: ";
	cin >> entries;

	// value of entries must be atleast	10: For demo, i will use two
	while (entries < 2) {
		cout << "You must input at least 10 records. Please input a bigger value.\n";
		cin >> entries;
	}

	cin.get();

	string temp;
	Person tmpPerson;
	for (int i = 0; i< entries; i++) {
		cout << endl << "Enter data for person #" << 1 + i << endl;
		cout << "What is the first name? ";
		getline(cin, temp);
		tmpPerson.setFirstName(temp);

		cout << "What is the last name? ";
		getline(cin, temp);
		tmpPerson.setLastName(temp);

		cout << "What is the age? ";
		//getline(cin, temp);
		//tmpPerson.setAge(stoi(temp));  // convert string to int

		//if stoi is a problem with your compiler
		int age{ 0 };
		cin >> age;
		tmpPerson.setAge(age);

		cin.get();

		cout << "What is the telephone number? ";
		getline(cin, temp);
		tmpPerson.setTelephone(temp);

		cout << "What is your email? ";
		getline(cin, temp);
		tmpPerson.setEmail(temp);

		persons.push_back(tmpPerson);

		++count; // increment count
		cout << endl;
	}
}

// use count here. Count is actually useless since person.size() == count
void People::showPersons()
{
	if (count == 0) { // if(persons.size() == 0) OR if(person.empty()) works too
		cout << "There are no entries yet!" << endl;
	}
	else {
		cout << "Person on record : " << count << endl;
		cout << "------------------------------------" << endl;
		for (auto &person : persons) {
			cout << person << endl;
		}
	}
}

It seems as if there is much information lacking in your program. If Employer has nothing addition, then i don't see the use here.

I am however guessing that, you are reading a book and this exercise is to make you wonder like assembling a plane.

This

Modify the Vector class to hold People objects instead of Record objects.

That is why i changed the class from Records to People

And this

Modify the menu interface and input algorithms to accept data for the Employer and Personal Info classes via functions in the Person class. Modify the Output to print all the information in each Person object, associated Employer object, and associated Personal Info object.

I think requires inheritance. If you have not covered that, then i guess you wait.

My solution(with assumption that you don't need inheritance) does not fullfil this last criterion.

Maybe our elders in the house can correct us. I am also an upper beginner(whatever that means).

[Griffinflame21]

The professor didn't really go into enough detail with the instructions, sadly. I don't understand why I even need the employer class or what goes in it, but the assignment says to have an employer class so.. :/ I asked, but no reply.

I'm using NetBeans. And yes, it does work with C++ 11 but I've never had this error before.

It is still giving the same errors. For some reason, not during compiling, it shows errors in People.cpp. There are quite a few but I think the most important one is 'Cannot find include file "People.h"'. That might fix all the other problems.
And 'Unable to resolve identifier size in People.h....

[Griffinflame21]

I've been working on it. I have one question.

void People::showPersons()
{
	if (count == 0) { // if(persons.size() == 0) OR if(person.empty()) works too
		cout << "There are no entries yet!" << endl;
	}
	else {
		cout << "Person on record : " << count << endl;
		cout << "------------------------------------" << endl;
		for (auto &person : persons) {
			cout << person << endl;
		}
	}
}

I don't understand the "for( auto &person : persons) part
could you explain that? What's different between person and persons, what does the : do?



EDIT:
I fixed the error....somehow! And it works! Thanks everyone for the help. Honestly never would have gotten this done without y'alls help. Much, much appreciated.

[longberns]

Glad you had it working. "Fixing" such kind of problem is part of programming.

The for(auto &person: persons) is a C++11 "cleaner" way for looping through a vector(and some std containers that have iterator). It is called range-for loop.
Read it here http://en.cppreference.com/w/cpp/language/range-for

Diff btn person and persons?
persons is a vector containing many person object. See People class.

for(auto &person: persons) could still be for(auto &stone: persons). I used person there so the loop can look as understandable as possible.

That said, the same range-for loop could be written as(which is ALSO correct) as

for (unsigned i = 0; i <count;i++){/*count is preferrably persons.size()*/
     cout<<persons[i]<< endl;
}

Hope you get a clearer mind now.
Good luck.
