 Parent/Child inheritance chains are a beneficial way to add specifications to classes without changing the base class functions.  An example of this may be Animals->Dogs: An animal would have a size, age, living/death status, which are all properties that a dog could inherit, however, a dog could have it's own functions like fur length, temperament, so on and so forth.  This could be extended by creating a dog breed class.  Parent/Child inheritance chains are a beneficial way to add specifications to classes without changing the base class functions.  An example of this may be Animals->Dogs: An animal would have a size, age, living/death status, which are all properties that a dog could inherit, however, a dog could have it's own functions like fur length, temperament, so on and so forth.  This could be extended by creating a dog breed class.

 +It’s also possible to inherit from a class that is itself derived from another class
 +====A reflection on the concept of inheritance====
 +(among other things)
 +
 +It is easier to understand inheritance than it is most concepts in programming, because inheritance follows so closely to where it gets its name from. If you asked a non-computer programmer what a string is it would likely make them think of a string of fabric, whereas if you asked them what inheritance is they would probably think of a concept the same as how inheritance functions in C++.
 +
 +Something Interesting to note is that child class cannot access the private information relating to their parents, but can still have them. For example, if plant(as a parent class of tree) has a private int of age, then tree will also have a private value of age. This is because when inheritance is activated it calls upon the parent's constructor, which can access the parent's private values.
 +
 +When something has multiple parents it is called multiple inheritance. When there is more than one tier of inheritance (grandparents) it is called multilevel inheritance. When something has multiple children it is called hierarchical inheritance. When multiple of these occur it is called hybrid inheritance.
 +
 +Inheritance allows us to reuse classes by having other classes inherit their members.
 +
 +It is possible to make a class non-subclassable (sterile) in C++ with the "final" keyword.
 +
 +COOL BUG FACT: Inheritance was first created for the Simula programming languages
