Your job is to implement two member functions in "student.h": addGrade(grade) and GPA( ). The addGrade(grade) function simply pushes the given grade into the Grades vector. The GPA( ) function returns the student's GPA based on their grades. Use standard numeric scoring: A => 4, B => 3, C => 2, D => 1, and F or W => 0. Assume no other grades are possible (e.g. let's ignore NR grades, S/U grades, etc.).

A main( ) program is provided that creates student objects and tests the various member functions. The program starts by creating 3 test students: pooja, drago, and sam. Here's the correct output:

pooja (12345): gpa is 2.75 drago (88425): gpa is 0 sam (99999): gpa is 2.2

/*student.h*/ is a todo file

// // student class for keeping track of grades. //

using namespace std;

class student { private: string Name; int UIN; vector Grades;

public: // // constructor: // student(string name, int uin) { Name = name; UIN = uin; // // Grades vector is automatically created via it's constructor // }

// // addGrade: // // Adds another grade to the Grades vector. // void addGrade(char grade) { // // TODO: push the grade into the Grades vector: // }

// // GPA: // // returns GPA for this student, based on their grades. Returns 0.0 // if the student has no grades. // double GPA() { // // TODO: loop through the Grades vector and compute the GPA. Note // that if the vector is empty, return 0.0. // return -1; }

// // getName // string getName() { return Name; }
