Recap and references

You have reached the end of week 3. During this week, you learned about a few topics that are required to do object-oriented programming in Fortran. You learned about

• user-defined types that allow you to build your own custom data types,
• modules that help you structure your code into units that facilitate code reuse and allow to restrict access to their content,
• interfaces that serve as types for procedures so they can be passed safely to other procedures as arguments,
• type-bound procedures, Fortran’s way of defining object methods, and
• inheritance, the mechanism to derive a new class from an existing one.

References

The books that were mentioned previously contain a lot of information and examples on the material covered in this week, so you should certainly check those. In addition, there is some material specific to this week’s content.
