I need help with my constructor and destructor.

This is the student information and database class declarations:

namespace cop3530 {

class student_info { std::string name; double gpa;

public: student_info(); student_info(std::string name, double gpa); etc... };

class student_db { // your bst cop3530::bst myDatabase;

public: student_db(); ~student_db(); void insert(const int student_id, const std::string &student_name, const double gpa); etc... };

}

In a separate .h file I have my binary search tree:

namespace cop3530 {

template class bst { struct node { Key key; T t; node *left = NULL; node *right = NULL;

node() {} node(Key k, T t): key(k), t(t) {} };

node *root = NULL;

public: bst(); ~bst(); void insert(const Key &key, const T &t); etc...

};

etc...

}

The student_db constructor is where I'm really stuck.

student_db::student_db() { // Constructs a student_db object, initializing necessary member variables, etc. }

And my bst constructor is,

template bst::bst() { root = NULL; }

I've tried multiple different ways of doing it but I'm not getting anywhere. Please help!
