Requirements: Your C program will read data from a text file (), store them in a linked list, perform some operations on the data, and write the processed data to another text file. An input text file contains data of students. The data for each student in the file consists of: student id (9 digit integer number), student name and surname (in a single field), birth date in "DD/MM/YYYY" format, gender ('F' for female, 'M' for male), department code (at most 5 characters) and class (int from 1 to 4). The fields are separated by a semicolon", Your cs363_hw2_surname_name.c C program will do the followings: Declare the necessary structures. (The birth date will be stored as a single integer number in the YYYYMMDD format.) Input from user the name of the input text file. Read all the data which is in this text file and store in a linked list. ATTENTION: The linked list will be sorted at all times by birth date of students. Display all students in the linked list Input a department code, and display students in that department Increment by 1 the class field of all students. Remove the nodes that has class value > 4 from this list, but add them to a second list. So do not free them, just add to a 2nd linked list. Display the first linked list again and display the second linked list Write your program as modular as it can be. The main program should mainly consist of necessary declarations and function calls.

Sample function call: ymd = dateStrInt("04/12/2018"); int dateStrInt(char str[]) { int d, m, Y; sscanf (str, "%d/%d/%d", &d, &m, &y); return (y * 10000 + m * 100 + d); } // end dateStrint // splitDate: separates day, month and year from YYYYMMDD int date. // Sample function call: splitbate (20181204, &day, Emon, &year); void splitbate (int ynd, int *dp, int *mp, int *yp) { *dp = ymd 100; *mp = (ymd / 100) 100; *YP ymd / 10000; | } // end splitDate
