What is The Difference Between Bliss And ALF, Programming Languages

Bliss 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 Bliss 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 Bliss Programming Language – A brief synopsis

It is a system programming language and was one of the best-known languages of this type till C came up. W.A. Wolf, D.B. Russell and A.N. Habermann of the Carnegie Mellon University developed Bliss. It includes exception handling mechanisms, coroutines and macros while it excludes the goto statement.

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.
