For any query about the assignment, contact at cs301p@vu.edu.pk
GOOD LUCK
Requirements:
§ Linked List will be used to store the information of all candidates.
§ The program will accept “Candidate Name” ,“subject test marks”, “interview marks” as input parameters.
§ The candidate will only be considered eligible for post of lecturer if he/she secures more than 70 marks in the subject test and more than 80 marks in the interview. Otherwise he/she will be considered ‘ineligible’
§ The program should display the record of eligible and ineligible candidates separately.
Solution Guidelines:
1) Understand and practice the following topics before developing this assignment::
R Nodes
R List
R Linked List
RLinked List Methods
2) To save candidate information, use the Linked List data structure. Each candidate will be represented by a node that contains the following information: candidate name,subject test score,interview marks,and status (eligible/ineligible).
3) Your solution should use these classes:
a. Candidate (Node) Class: To save information of each candidate
b. List Class: To save all candidates in linked list
Sample Output
