Question

Develop a system/application in Prolog that will allow grader to:

  1. load a set of student’s grades (see samples from the Table C below)
  2. query student’s final letter grade (A, B, C, etc.) by a given student’s name.
  3. query student(s) whose grade matches to the input letter grade (e.g., A). For example, show student(s) whose final letter grade is A.

There are 3 types of grades for each student—HWs, Exams, and Project, with a weight of 20%, 40% and 40%, respectively, to the 100-point final.

Table A and B show how the final grades (in points and letter) are computed.

Table C shows samples of students’ grades.

You will define the execution instructions to answer the following questions so that grader can test out your application in Prolog:

  1. how to load your source code to Prolog runtime/compiler
  2. how to load students’ grades to Prolog runtime/compiler
  3. how to query student’s letter grade
  4. how to query student(s) whose letter grade matches to an input letter grade

Please DO NOT hard code any input values, output values in your code.

PLEASE USE ONLY PROLOG AND NOT ANY OTHER PROGRAM
