Maybe he only knew C as you say. I did C++ professionally for a while. Not properly, just updating models in derivatives trading systems. I remember reading 3 Scott Meyer books, the Effective Programming series, at the time, they were a tour de force. Loved that guy. I've lost track of everything since 11 or whenever they introduced move semantics. One day I might go back to it.

Nowadays it's "rule of zero": compiler-generated constructors, destructor, assignments, compare. The members are of types smart enough on their own.

Lambdas are generic now, and variadics work most places.

Velocity has shot up. Fun, too.
