Your question is in incorrect english unclear ( how does the two assignAssociate functions differ? which parameter should we templatise?) and overall very confusing.

Which is probably why there is no previous comment on it before this one.

However to make a bleak attempt at what you are looking for:


class Principal_mentor{

public:

Principal_mentor(<pass container for course>);

~Principal_mentor(); // destructor

private public or protected( as you would want it to be):

template <class A classB...(however many template parameters you'd like)> void assignAssociate(A courseId B FacultyId C role); //Method1

template <class A class B> void assignAssociate(A courseId B FacultyId); //Method2
private:

File * faculty;

File * associates;

<declaration of container for course>;
}

Principal_mentor::Principal_mentor(<argument which is container for course>):<instantiate container for course member in the initializer list>

{

faculty fopen(faculty.txt "r"); //please check the correct syntax for the fopen

associates fopen(associates.txt "w"); // --do--

}

Principal_mentor::~Principal_mentor()

{

fclose(faculty);

fclose(associates);

}

template <class A classB...(however many template parameters you'd like)> void assignAssociate(A courseId B FacultyId C role)
{
//read one faculty name from file handle faculty
//assign it to a course.
//determine the role however you want to
//write courseId FacultyId role line into associates file handle using write or fwrite properly.
}

// construct Method2 in similar fashion.

Hope this helps you.
