Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness.

• Subtypes must be substitutable for their base types.

• Derived classes must be able to replace their base classes without affecting the program's behavior.

• Violating this principle can lead to unexpected behavior and errors in the code.

• Example: If a program expec...read more
