Write the implementation file for the TestScore class in Exercise 1. The constructor just assigns its parameters to the private data members, and the observers simply return the corresponding member.

Exercise 1

Given the following declaration for a TestScore class, write a derived class declaration called IDScore that adds an integer student ID number as a private member, and that supplies (1) a constructor whose parameters correspond to the three member fields, and (2) an observer that returns the ID number.

class TestScore{public:  TestScore(string name, int score);  string GetName() const;  int GetScore() const;private:  string studentName;  int studentScore;};
