What are the building blocks of the prolog?


Asked by Grace Richmond on Dec 10, 2021 FAQ



These building blocks are Facts, Rules and the Queries. We can define fact as an explicit relationship between objects, and properties these objects might have. So facts are unconditionally true in nature. Suppose we have some facts as given below − Pratyusha is lazy. So these are some facts, that are unconditionally true.
Likewise,
Prolog language basically has three different elements − Facts − The fact is predicate that is true, for example, if we say, “Tom is the son of Jack”, then this is a fact. Rules − Rules are extinctions of facts that contain conditional clauses. To satisfy a rule these conditions should be met.
Furthermore, A closure is a term that denotes a Prolog goal to which zero or more arguments are added before it is called. The mechanism to invoke arbitrary Prolog goals dynamically is called meta-call, and it is the basic building block by which we can define arbitrary meta-predicates in Prolog.
One may also ask,
Facts, Rules and Queries − These are the building blocks of logic programming. We will get some detailed knowledge about facts and rules, and also see some kind of queries that will be used in logic programming.
Moreover,
A partial goal is a term that denotes a Prolog goal to which zero or more arguments are added before it is called. The mechanism to invoke arbitrary Prolog goals dynamically is called meta-call, and it is the basic building block by which we can define arbitrary meta-predicates in Prolog.
