Question

write code data structure using  c language

You will build a system to manage patients’ data in a hospital. The hospital patient management system stores specific information in the form of health record to keep track of the patients’ data. Your program should read the information from a file called “patients.txt” that should be on the following format

: Patient Name#Gender#Date of admission#Date of birth #Illness#Address (City)#Blood type

Your program should be able to do the following tasks: Options: 1. Read data: read the data of the patients from the file.

2. Create linked list: create a linked list.

3. Sort data: use Radix sort to sort the data based on the patients’ names.

4. Add patient: add a new patient.

5. Update patient: update patient’s information.

6. Delete patient: soft delete (explained below).

7. Search for patients a. Name b. Date of birth

8. List patients a. All patients b. Category (i.e., illness) c. City d. Discharged (Patients who were deleted from the system)

9. Export medical report: export XML file following medial health record standards.

10. Exit: exit from the system and store the information back to the file.

you are not allowed to use the String library functions.
