(C++) inheritance

Inheritance is a technique to re-use members of a class.

There are multiple types of inheritance:

• implementation inheritance
• interface inheritance
• multiple inheritance

There are three modes of inheritance:

1. public inheritance, an 'is-a-kind-of' relationship, the most commonly used mode of inheritance
2. protected inheritance, an obscure type of relationship
3. private inheritance, an 'is-implemented-in-terms-of' relationship [1]

Examples

advice

• Prefer composition to inheritance [2]

Notes to self

• When in doubt, don't use inheritance: it is far far easier to correct when you've used composition too long, than the other way around
