// READ BEFORE YOU START: // You are given a partially completed program that creates a list of pets with their list of absents. // Each student has the corresponding information: name, standard, and a linked list of absents. // To begin, you should trace through the given code and understand how it works. // Please read the instructions above each required function and follow the directions carefully. // If you modify any of the given code, the return types, or the parameters, you risk failing the automated test cases. // // You are to assume that all input is valid: // Valid name: String containing alphabetical letters beginning with a capital letter // Valid standard: String containing alphabetical letters beginning with a number // Valid date: String in the following format: "MM/DD/YYYY" ex: "01/01/2010" // All input will be a valid length and no more than the allowed amount of memory will be used // // Q1 : CLASS METHODS Part 1 : Constructor and Accessor Methods for Student class in Student.cpp file ( 5 points) // Q2 : CLASS METHODS Part 2 : Class methods for Student class in Student.cpp file (10 points) // Q3 : Add Function in hw09.cpp file ( 5 points) // Q4 : Search Function in hw09.cpp file (10 points) // Q5 : Remove One Function in hw09.cpp file (15 points) // Q6 : Implement cin / cout for the lines in main without modifying the functionality ( 5 points)

// Q1 : CLASS METHODS Part 1 : Constructor and Accessor Methods for Student (5 points)

// Constructor // Create a constructor for the class Student which takes 2 string parameters (see helper function for use of constructor). // Use the 2 string parameters to initialize the 2 private local variables name and standard. // HINT: Don't forget to initialize your linked list of absents to NULL.

//ENTER CODE HERE

// Accessor Methods // Create accessor methods for both private local strings name and standard (see print_all function for use of these methods).

//ENTER CODE HERE

// Q2 : CLASS METHODS Part 2 : Class Methods for Students (10 points)

// Create a method named "addAbsent" which has one string parameter and no return type (see helper function for use). // This method is used to add a new date to the student's linked list of absents. The string parameter is the date of absents. // You should add the date to the tail of the linked list "absents". Absents will be added in chronological order.

//ENTER CODE HERE

// Create a method named "lastAbsent" which has no parameters and returns a string (see print_all function for use). // This method will be used to return a string for the date of the last checkup for this student. // If the student has not yet had an absent, return an empty string.

Q1: Constructor and Accessor Methods for Student class (5 points) You will need to write the constructor and accessor methods for the Student class in the Student cpp file. The program will not compile until this part is completed. The constructor and accessor methods are already declared in the Student.h file. (See Student cpp file for details).
