Other options are Java-like. 4 Destructors release resources when an object goes out of scope or is deleted. 5 Inheritance promotes code reuse and extension of behavior. 6 Virtuals enable polymorphic dispatch; non-virtuals are bound statically. 7 Private restricts access; protected allows derived classes with some access. 8 Try-catch-throw handles runtime errors gracefully. 9 new allocates; delete frees single objects (delete[]) for arrays. 10 Overloading is same name, different params; overriding requires same signature in a derived class.
