Eiffel is an object-oriented programming language designed for software reliability, reusability, and maintainability. Created by Bertrand Meyer in the 1980s, Eiffel is based on the principles of Design by Contract, which emphasizes specifying and enforcing clear preconditions, postconditions, and invariants in code to ensure correctness and robustness.
Eiffel's syntax is clean and concise, with strong support for object-oriented concepts such as inheritance, polymorphism, and dynamic dispatch. One of its distinguishing features is the ability to define reusable, highly modular software components, making it well-suited for large-scale systems and applications that require high reliability.
Although it has not reached the mainstream popularity of languages like Java or C++, Eiffel is still used in fields like finance, engineering, and academia, where software correctness and maintainability are critical. Its emphasis on formal methods and software quality makes it a compelling choice for developers focused on building highly reliable systems.
