Question

C++ HW

Aim of the assignment is to write classes. Create a class called Student. This class should contain information of a single student.

last name,

first name,

credits,

gpa,

date of birth,

matriculation date,

** you need accessor and mutator functions. You need a constructor that initializes a student by accepting all parameters. You need a default constructor that initializes everything to default values. write the entire program.
