Difference between private, public, and protected inheritance?

Question

What is the difference between `public`, `private`, and `protected` inheritance in C++? All of the questions I've found on SO deal with specific cases.

Answer 1

Access	public	protected	private
Same class	yes	yes	yes
Derived classes	yes	yes	no
Outside classes	yes	no	no

A derived class inherits all base class methods with the following exceptions −

1. Constructors, destructors and copy constructors of the base class.
2. Overloaded operators of the base class.
3. The friend functions of the base class.
4.
