What you need to do:1. Type that code up and run it to make sure that it is doing what it is supposed to do. Provide the strings in the header of the program when prompted.2. Use the logic in that program to design your own Recursive Descent parser in C for the following grammar:S →aABA →Abc | bB →d3. Make sure that you choose at least two strings that pass the grammar and one string that does not pass the grammar just like I did in the model program4. Submit both the code and a screen shot of your results for the choice of strings that you provided.

Develop a system/application in Prolog that will allow grader to: load a set of student’s grades (see samples from the Table C below) query student’s final letter grade (A, B, C, etc.) by a given student’s name. 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: how to load your source code to Prolog runtime/compiler how to load students’ grades to Prolog runtime/compiler how to query student’s letter grade how to query student(s) whose letter grade matches to an input letter grade Please DO NOT hard code any…
