This is a program that inputs, processes, and outputs a set of student records organized as a vector of class StudentRec objects.
- the program should ask for the data to fill a studentRec of class StudentRec and then ask y/n if they want to add another studentRec.
- Each studentRec will go into the vector of type StudentRec called student_list.
- After the student records have been entered into the vector student_list, find the average gpa of all the students in the vector.
- Output all the student records and give the average gpa for the students.
