A memory-based file system.

A memory-based file system.

Assume that the structure:

struct personNode {

int ID;

char lastName[20];

char firstName[20];

int age[3];

struct personNode *nextPtr;

};

You have a file named person.csv.

You need to write codes for implementing five functions:—-

1) Input function: Input 20 last names, first names, ages, and write them to the file.

2) Load function: Read data from the file, then covert the data to a linked list. Display the average age from the the linked list.

3) Search function: search the linked list by ID, first name, last name, and age.

4) Delete a record of the linked list, then show the changed average. After doing that, please remove the record from the file.

Input 20 records:
