C++ London Uni: Member access exercise

The file student.hpp contains the definition of a simple student class.

It is common in object-orientated code to use accessor functions to access member variables. Your goal is to modify the student class to increase its encapsulation.

Tasks:

1. Add a constructor taking first, last and id variables. Assign these to the class's member variables using a member initializer list.

2. Add a member function get_first_name() which returns the first_name field of student. What should the return type of this function be? Why?

3. Add a set_first_name() member function to allow modifying the first_name field.

4. In set_first_name(), ensure that the name saved in the member variable begins with a capital letter, followed by all lower case letters (hint: look up the std::toupper() and tolower() functions)

5. Add accessor functions for the last_name and id fields.

6. Make student a class rather than a struct. Set the access levels of its member functions/variables appropriately.

7. How can we make the output stream function work properly again?
