Description
In Haskell, every expression possesses a type that is established during the compilation process. The types involved in function applications must align correctly; otherwise, the compiler will reject the program. This strict type system not only serves as a guarantee of correctness but also functions as a language for articulating the construction of programs. Each function in Haskell adheres to the principles of mathematical functions, meaning they are "pure" in nature. Even when dealing with side-effecting IO operations, they merely outline actions to be taken, generated by pure functions. Haskell does not utilize statements or instructions; instead, it relies solely on expressions that cannot alter variables, whether local or global, nor can they manipulate states such as time or randomness. While it is not necessary to specify every type in a Haskell program, the types can be inferred through a process of bidirectional unification. Still, programmers have the option to explicitly define types as needed or request the compiler to generate them for reference, thereby enriching documentation and enhancing clarity. This flexibility allows Haskell developers to strike a balance between type safety and ease of use.
Description
Prolog is a programming language based on logic that is closely linked to the fields of artificial intelligence and computational linguistics. Originating from first-order logic, which is a type of formal logic, Prolog distinguishes itself from many other programming languages by being primarily a declarative language, where logic is conveyed through relations that are defined by facts and rules. To begin a computation, one must execute a query against these established relations. As one of the pioneering logic programming languages, Prolog continues to enjoy widespread popularity today, supported by various free and commercial implementations. This versatile language has found applications in diverse areas such as theorem proving, expert systems, term rewriting, type systems, automated planning, and its foundational purpose of natural language processing. Additionally, contemporary Prolog environments offer capabilities for developing graphical user interfaces, alongside support for both administrative tasks and networked applications, further demonstrating its adaptability in modern programming contexts.
