If you've ever wondered how software that controls airplanes, medical devices, or other systems where a failure can have serious consequences is programmed, SPARK is the language for that job. It's not just a variant of Ada - it's a stricter, more analyzable version that lets you mathematically prove that your code does exactly what it's supposed to, and nothing else.

SPARK relies on so-called contracts - formal specifications that describe what each part of a program should do. These contracts can be verified both statically and dynamically, which means many bugs can be found before the program even runs. It's like having a built-in quality inspector that never sleeps.

So if you work in domains where reliability is not just desirable but absolutely essential, SPARK is a tool that can help you build systems with the highest possible integrity.
