Prologue Programming Concepts

The video tutorial introduces the basics of Prolog programming, focusing on the concept of a knowledge base, which consists of facts and rules. It explains how to write Prolog syntax, including variables, facts, and rules, and demonstrates how to make queries using logical operations. The tutorial provides examples to illustrate how facts and rules are used to derive conclusions in Prolog.

What is a knowledge base in Prologue programming compared to?

• A library

• A computer

• A database

• A human brain

In Prologue, what symbol is used for the logical operation 'if'?

• Comma

• Colon and hyphen

• Semicolon

• Keyword 'not'

How do variables in Prologue typically start?

• With a lowercase letter

• With a number

• With a capital letter or underscore

• With a special character

Which of the following is a correct way to write a fact in Prologue?

• fat: Johnny.

• Johnny is fat.

• Johnny: fat.

• fat(Johnny).

What does a rule in Prologue typically consist of?

• A list of variables

• A combination of facts and conditions

• A single fact

• A sequence of numbers

What is the outcome if a query matches a fact in the knowledge base?

• Error

• False

• True

• Unknown

In Prologue, what does the 'or' symbol indicate in a rule?

• Both conditions must be true

• Neither condition can be true

• The rule is invalid

• At least one condition must be true

What happens if a rule uses 'and' and one condition is false?

• The rule is ignored

• The rule is incomplete

• The rule is true

• The rule is false

Which query would return true if the rule uses 'or' and one condition is true?

• Both conditions must be false

• At least one condition must be true

• Both conditions must be true

• Neither condition can be true

What is the result of a query if both conditions in an 'and' rule are true?

• True

• False

• Unknown

• Error
