Problem statement

A secure data system processes sensitive documents using distinct protocols for physical printing and digital encryption. Both protocols require a generic Process() command, creating a naming collision. Implement both protocols on a single document class securely.

Task requirements

• Define IPrintable and IEncryptable interfaces that both declare a Process method.

• Create a TopSecretBriefing class that implements both interfaces and provides distinct logic for printing and encrypting.

• In Program.cs, cast the instantiated class and execute both processes sequentially.

Constraints

• You must use explicit interface implementation for both Process methods to hide them from the class's default public scope and resolve the naming collision.

• IPrintable.Process must output exactly "Printing physical copy..." and IEncryptable.Process must output exactly "Encrypting digital file...".

• In Program.cs, you must cast the TopSecretBriefing instance to each respective interface type before you can invoke the Process methods.

• You must place all types in the Security file-scoped namespace.

Good luck trying the exercise! If you’re unsure how to proceed, check the “Solution” tab above.

Get hints

• Explicit implementations do not use access modifiers like public.

• The syntax for explicit implementation prefixes the interface name to the method name (e.g., void IMyInterface.MyMethod()).
