expected class name before '{' token. C++ inheritance - c++

Question

I've spent quite a few hours researching and trying to figure out why I'm getting this error. Basically the three files that have to do with the inheriting are CollegeMember.h, Employee.h, and EmpAcademicRecord.h. Employee. is inheriting from CollegeMember.h and EmpAcademicRecord.h is inheriting from Employee.h. Like this CollegeMember <- Employee <- EmpAcademicRecord. The error occurs in EmpAcademicRecord.h. Heres the three files.
CollegeMember.h
#include <cstdlib>
#include <iostream>
#include<ctype.h>
#include<string.h>
#include "Employee.h"
#include "Student.h"
using namespace std;
// ****************************************************************************
// Class Definitions follow
typedef char* String;
// The CollegeMember class
class CollegeMember
{
protected:
int ID_Number;
string FirstName, LastName;
string AddressLine1, AddressLine2, StateProv, Zip;
string Telephone;
string E_Mail;
string answer, answer2, answer3, answer4;//used as sort of booleans for use with validation
// member functions
public:
CollegeMember ( ); // constructor
CollegeMember(const CollegeMember&); //overloaded constructor
void Modify (CollegeMember Member);
void InputData(int x);
string Summary ( ); //summary
string PrintMe(); //fully describes
}; // End of CollegeMember class declaration
Employee.h
#include <cstdlib>
#include <iostream>
#include<ctype.h>
#include<string.h>
#include "EmpAcademicRecord.h"
#include "EmpEmploymentHistory.h"
#include "EmpExtraCurricular.h"
#include "EmpPersonalInfo.h"
#include "EmpPublicationLog.h"
using namespace std;
// ****************************************************************************
// Class Definitions follow
typedef char* String;
// The Employee Class
class Employee: protected CollegeMember
{
float Salary;
protected:
string Department, JobTitle;
// Member Functions
public:
Employee ( ); // constructor
void Modify (Employee ThisEmp);
void InputData(int x);
void SetSalary (float Sal) // Specified as an in-line function
{ Salary = Sal;}
float GetSalary ( ) {return Salary;} // Specified as an in-line function
string Summary ( ); //summary
string PrintMe(); //fully describes
}; // End of Employee class declaration
EmpAcademicRecord.h
#include <iostream>
#include <cstdlib>
#include<ctype.h>
#include<string.h>
using namespace std;
typedef char* String;
class EmpAcademicRecord: protected Employee{ //error occurs on this line
protected:
int ReferenceNumber;
string Institution;
string Award;
string start;
string end;
public:
EmpAcademicRecord();
void InputData (int x);
void Modify(EmpAcademicRecord ThisRec);
void Summary();
};
Any help with this would be greatly appreciated.

Answer 1

That sort of error is usually caused by the type not being defined when you try to use it.
In this case, it appears that you may have included EmpAcademicRecord.h without having first included Employee.h (the includes at the top of the former do not show the latter).
In other words, at the point where the compiler sees:
class EmpAcademicRecord: protected Employee { //error occurs on this line
it has no idea what the Employee class is.
It may be a simple matter of adding:
#include "Employee.h"
to the top of that file, it's a little difficult to be certain since we don't have the code files. In any case, it's certainly a good first step.
Since you have EmpAcademicRecord.h being included by Employee.h, that will probably result in an infinite recursion.
You could fix that with include guards, but I can't see why you need that particulat inclusion. EmpAcademicRecord depends on Employee, not the other way around.
