Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector.
