>>21C++ is designed for perfection. Where other languages give you a feature, C++ gives you meta-features. Instead of built-in strings and vectors, it gives you templates. Instead of garbage collection, it gives you smart pointers. This way, you can (theoretically) implement your own "perfect" (most efficient and generic) strings. In practice, this turns into a nightmare since many different kinds of strings, smart pointers, etc., each perfect in its own way, will not work with each other. C++ sacrifices usability for perfection.
This leads to C++ being outstandingly complex because it deals with a lot in order to give programmers this level of perfection.
