# CS508 Assignment No 03 Solution & Discussion Spring 2013

kindly discuss this assignment here.

 Assignment No. 03 Semester: Spring 2013 Modern Programming Languages  (CS508) Total Marks: 15   Due Date:  26/06/2013 Instructions: Please read the following instructions carefully before submitting assignment:   You will submit your assignment before or on due date on VU-LMS. Assignment should be completed by your own efforts it should not be copied from internet, handouts or books. You should submit your MS Word File via assignment interface at VU-LMS. Assignment sent via Email will not be replied and accepted/graded in any case. If the submitted assignment does not open or file is corrupt, it will not be graded. You will submit solution only in Microsoft Word File.   Objectives:   To understand and familiarize with Prolog Language. For any query about the assignment, contact at cs508@vu.edu.pk or through MDB. Assignment Questions Suppose you have the following observational data about students of college.   Ali studying Artificial Intelligence. Ahmad is studying Artificial Intelligence. Mujahid is studying Artificial Intelligence.   Jawad is studying Artificial Intelligence. Akram is studying Artificial Intelligence.   Mehvish is studying Computer Vision. Sobia is studying Computer Vision.   Mujahid is Studying Computer Vision. Ahmad is Studying Computer Vision. Jawad is studying Computer Vision. Abdullah is studying Computer Vision.   Abdullah is studying Encryption Techniques. Fahad is studying Encryption Techniques. Mehvish is studying Encryption Techniques. Imran is studying Encryption Techniques.   1.      Now being a prolog programmer answer the following questions:   Question # 1                                                                                                                              Marks 5        Write the prolog rules for the followings.   If one is studying Artificial Intelligence and Computer Vision then perquisite is Discrete Structure.                                                          I.      If one is studying Encryption Techniques and Computer Vision then Perquisite is Discrete Structure and Analysis of Algorithms.                                                       II.      If one is studying only Encryption Techniques then prerequisite is Analysis of Algorithms.                                                    III.      If one is studying Encryption Techniques and Artificial Intelligence then one is expert in Efficient Security Algorithms.                                                    IV.      If one is studying only Artificial Intelligence then one is Intellectual.       Question # 2                                                                                                                              Marks 10      Write the prolog queries for the followings. These queries will be executed according to the facts and rules defined for the above given data and perform all steps to write the output of the given queries.   a.      Is there prerequisite of Discrete Structure for X? b.      Is there prerequisite of Discrete Structure and Analysis of Algorithms for Y? c.       Is there prerequisite of Analysis of Algorithms for Z? d.      Is Sobia Studying Artificial Intelligence? e.       Are Abdullah and Imran Studying Encryption Techniques? f.       Is P studying Computer Vision and Artificial Intelligence?   Note: In queries where variables are used along with answer write all the possible matches either they are true or not. BEST OF LUCK

No,

apply conjunction in ur query.

further, according to me..

for ET ,prerequisite will be Analysis of Algorithm

for CV ,prerequisite will be DS

for Ai  , have to select intellectual

there is .

look.

in first rule. for Artificial intelligence, we have to select intellectual, so for Computer Vision's prerequisite will be DS.

give any examples?

like keep student in variable,
If one is studying Encryption Techniques and Computer Vision then Perquisite is Discrete Structure and Analysis of Algorithms.

solution:
student(A) :- isa(A,Encryption Techniques, Computer Vision), isa(A, Discrete Structure, Analysis of Algorithms)

thanks yaar and plz tell me is it rite?

a.    Is there prerequisite of Discrete Structure for X?

?- perquisite (Discrete Structure, X)

X=Ahmad

X= Mujahid

X= Jawad

one thing is wrong, space is not allowed in attom names.

yaar aap log kia ker rahi ho or confuce ho raha hn ap koi examples do gy? plz

Imran Faisalabad example book pe ha hum usko discuss kr trahe hn ap wahan se resd karo samjh ajy ga

sny2ksa what is meaning of X there?

in query ..X can only be any variable in which u can save subject name.
because prerequisite can only assign to subjects, not to students

some infos regarding PROLOG>

we can't have variables in Facts. but in Rules and queries can have

variable name starts with capital letter or underscore.

u have to be consistent through out ur program after deciding about object and subject places.
