Question
In C++:
You’ve been given a skeleton of the code, but you need to fill in the parts of the functions relating to the Transcript variable; note that in addition to initializeStudent and printStudent, I’ve also incorporated a mergeStudent function. You will modify printStudent, initializeStudent, and mergeStudent to handle the parts of the Student relating to their Transcript. In initializeStudent, you should add code to read in the students’ courses and grades. From the grades entered, you should compute the student’s gpa. In printStudent, you should add code to print out the students’ courses and grades, and their gpa. In mergeStudent, you should add code that will include all courses from both students (but with no duplicates) and compute the new gpa, and store these values into the returned Student. The idea of the mergeStudent function is that there may be two duplicate variables representing the same student, and you want to come up with a new variable based on those.
