I am getting error C2061: syntax error : identifier 'novice' for all of my new declarations

It's not picking up your novice declaration. Have you called it Novice instead? Remember C++ is case-sensitive.

Edit: It's also better to use vector.push_back() instead of assigning it like an array as you are doing.

novice.h is my header file name this is happening for all of my novice standardSupportPerson and expert headers I have checked to make sure they are all spelled and cased correctly. I am not familiar with the vector.push_back() as I have only been doing c++ for a little over 3 months now. my problem seems to be in the vector block as I have commented out the lines and my program compiles fine.

Can you post the contents of novice.h please.

however I am not getting the identifier error with this EasyCaller.h

This is supposed to be a call center simulator that is divided into parts this part is using abstract and concrete classes
Zaita (2770)
Your supportPerson needs to implement the functions getMultiplier, getType and it's constructor with 1 argument. Otherwise, make the functions pure-virtual.
growe79 (23)
This is supposed to be an abstract class the uses the concrete classes to getmultiplier and constructor of each derived class. Atleast that is how it was explained to me by my professor
Zaita (2770)
If it's abstract then it cannot be instantiated. 

1
2
 
virtual int getMultiplier() = 0;
virtual string GetType() = 0;
growe79 (23)
so it should read 
1
2
 
virtual int getMultiper();
virtual string GetType();

??

class supportPerson : public callParticipant

public:
virtual int getMultiplier() = 0;
virtual string GetType() = 0;
};

ok so why am I getting the problem with my concrete classes that they are not recognized identifiers?
Zaita (2770)
In supportPerson.h you have #include "Caller.h"
make it callParticipant.

Also. I don't know why this is an abstract/concrete task. I would've done it like this.

what does the push_back do exactly?
Zaita (2770)
adds the element to the vector.

Thank you for your help Zaita
