What is The Difference Between ALGOL And ALF, Programming Languages

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

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)

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)

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

Let us now look at the difference between the two:

What is ALGOL Programming Language – A brief synopsis

Algorithmic Language, as it is called, is actually a family of imperative programming languages that was developed in the middle 1950s. It proved instrumental in the creation of programming languages like BCPL, B and C. Ole-Johan Dahl and Kristen Nygaard of the Norwegian Computing Center in Oslo were the brains behind Simula.

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.
