What is The Difference Between ALF And D, Programming Languages

ALF is a Logic-based Programming Language, while D is a Compiled Programming Language

What are Logic-based Programming Languages

Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. (Wikipedia)

What are Compiled Programming Languages

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place). (Wikipedia)

While ALF is a Logic-based Programming Language, and D is a Compiled Programming Language

Let us now look at the difference between the two:

What is ALF Programming Language – A brief synopsis

Algebraic Logic Functional Programming Language is a multi-paradigm programming language that is a combination of functional programming and logic programming. ALF program statements are compiled into instructions of an abstract machine. An emulator written in C executes the programs of the abstract machine.

What is D Programming Language – A brief synopsis

Originally designed as an enhancement of C++, it is also influenced by Java, Eiffel, and C#. It is an object-oriented, imperative, multi-paradigm system programming language developed by Walter Bright of Digital Mars.
