SPARK is a programming language that is designed for high-integrity systems, emphasizing safety, security, and reliability. Developed in the late 1980s by AdaCore, SPARK is based on the Ada programming language, and it extends Ada with formal specification and verification features that support the development of critical software systems. The language was created to meet the stringent requirements of applications in domains where safety and correctness are paramount, such as aerospace, automotive, and medical systems.
