Inheritance
<strong>Inheritance</strong> lets a derived (child) class inherit all data and functions from a base (parent) class, enabling code reuse and the 'is-a' relationship.
01Basic Inheritance
The derived class automatically has all public and protected members of the base class.

02Calling the Base Constructor
When a Derived object is created, the Base Constructor runs FIRST! Pass arguments to it via the initializer list.
main.cpp
Terminal

03Function Overriding
A derived class provides its own version of a base class function. Without 'virtual', the base version always runs through a base pointer.

04Multi-Level Inheritance
A derived class can be the base for another class, creating a chain. Each level inherits from all above it.

05Calling Overridden Base Method
Even after overriding, explicitly call the original base version using BaseClass::method() syntax.

06Multiple Inheritance
A class can inherit from MORE than one base class. Use carefully - prefer interfaces (abstract classes) when possible.

Instead of writing fly() for Eagle, Hawk, and Parrot separately, write it once in Bird and all three inherit it automatically.
