Creational Design Patterns in Modern C++ - S.O.L.I.D. Principles - Part II

The video tutorial discusses the principles of inheritance and the importance of maintaining consistent behavior in subclauses. It highlights the open-closed principle and Liskov substitution principle, using an example of an operation clause that performs arithmetic operations. The tutorial addresses the challenge of adding Boolean operations without violating these principles and proposes a solution using an interface and variant to ensure type safety and flexibility in client code.

What is the role of the IOperation interface in the context of the operation and bool operation clauses?
