CppCon 2021

This session is part of the Software Design Track.

Many engineering disciplines require alterations or improvements of existing systems to be "up to code," whether that be the installation of railings on a staircase or upgrades to electrical work. In this talk, we'll apply this concept to Software Engineering and, in particular, C++-based systems. Using one real-world example, we'll cover best practices including: contracts, type-driven architecture, hierarchical design, and difficult testing scenarios as they apply to "old work."

While many of these topics are covered elsewhere, they are usually presented as if all code is being written from scratch. Application to an existing system is an entirely different matter. That is the subject of this talk.
