In addition to performance, expressiveness, and portability, C++ offers a set of language features that gives the programmer the ability to write robust code.
In our experience, robustness does not refer to strength in the programming language itself – it's possible to write robust code in any language. However, strict ownership of resources, const correctness, value semantics, type safety, and deterministic destruction of objects are some of the features offered by C++ that makes it easier to write robust code. That is, the ability to write functions, classes, and libraries that are easy to use and hard to misuse.
