Ada (programming language)

Ada is a programming language developed for the US Department of Defense to address software reliability challenges in mission-critical programs. Designed for safety-critical and real-time embedded systems, it enforces strict data type rules that prevent incompatible operations, promotes modular structure, and provides native support for managing parallel processes, reducing the risk of runtime errors. 

Ada is widely used in aerospace, defense, rail, civil aviation, and medical devices, where rigorous certification and safety standards govern software development practices. Its strict ability to catch errors at compile time, before execution, and its predictable runtime behavior make it a preferred choice for long-lifecycle, high-integrity systems.
