Design-by-Contract's invariant attribute allows you to enforce important properties of systems and data structures, making it an incredibly useful tool for developers. In this blog post, we'll be exploring the development of a GCC plugin that adds support for [[invariant]] conditions in C++ classes and structs. We'll also be looking at an example of how invariant can be used to improve the integrity of a Stack data structure. This is especially timely as GCC has recently added support for Contracts, allowing you to annotate functions with pre/post conditions. Don't miss out on learning how to use this powerful feature in your own projects!
