Logic Programming Paradigm & Prolog Basics

What is the definition of Logic Programming Paradigm?

• A programming paradigm where programs are written in the form of logical rules and facts to derive answers to queries.

• A programming paradigm where programs are written in the form of mathematical equations

• A programming paradigm where programs are written in the form of procedural steps

• A programming paradigm where programs are written in the form of visual diagrams

Explain the basic concepts of Logic Programming.

• Logic Programming focuses on visual design and user experience.

• Logic Programming involves writing code in a procedural language.

• Logic Programming is based on mathematical equations and calculus.

• Logic Programming involves defining facts and rules, and querying the system to derive new information.

Select an example of Logic Programming language.

• Java

• C++

• HTML

• Prolog

In Prolog, how are facts defined?

• Facts in Prolog are defined by ending with a question mark.

• Facts in Prolog are defined by using quotation marks around the predicate.

• Facts in Prolog are defined by using curly braces.

• Facts in Prolog are defined by stating the predicate followed by a period.

What are rules in Prolog programming?

• Rules in Prolog programming are used to define the valid statements.

• Rules in Prolog programming are used to define questions based on given statements.

• Rules in Prolog programming are used as statements in form of queries.

• Rules in Prolog programming are used to define relationships between entities or facts by specifying the conditions.

How are queries used in Prolog?

• Queries in Prolog are used to retrieve information from the knowledge base by posing a question to the system.

• Queries in Prolog are used to execute predefined functions.

• Queries in Prolog are used to delete information from the knowledge base.

• Queries in Prolog are used to store data in the knowledge base.

What is the main characteristic of Logic Programming Paradigm?

• Object-oriented programming

• Functional programming

• Imperative programming

• Formal logic representation

Give an example of a real-world application where Prolog is used.

• Financial system

• Medical diagnosis system

• Student registration system

• Operating system

How are variables represented in Prolog programming?

• Variables in Prolog programming are represented by starting with a dollar sign.

• Variables in Prolog programming are represented by using square brackets.

• Variables in Prolog programming are represented by starting with an underscore.

• Variables in Prolog programming are represented by starting with an uppercase letter.

A predicate expression that makes a declarative statement about the problem domain represents a

• fact

• rule

• query

• relation
