What is The Difference Between Modula-2 And ALF, Programming Languages

Modula-2 is a Procedural Programming Language, while ALF is a Logic-based Programming Language

What are Procedural Programming Languages

Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.

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 Modula-2 is a Procedural Programming Language, and ALF is a Logic-based Programming Language

Let us now look at the difference between the two:

What is Modula-2 Programming Language – A brief synopsis

It is a general-purpose procedural language created in 1978 by Niklaus Wirth at ETH. It is similar to Pascal and has systems programming and multiprogramming features.

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.
