I need help with this C program.

1. I need to create a "phonebook.c" program that should read the "addresses.csv" CSV file when the prgogram is ran the first time (the file contains people's first and last names, phone number and address)

a. also, any other time the program starts, it should not read from this file, rather from a binary file.

b. the program should store each person into a linked list (linkedList.c) of structures that hold the information given in the file.

2. Once it is done then, the program should sort the list by last name. If there are multiple last names then the program should then sort by first names (example, "Smith, Amy -then- "Smith, Sam")

3. Then the program should print a menu to the user with the following options:

a. Print the Phone List

b. Add a Person

c. Delete a Person

d. Find a Person

e. Save and Quit

the program should loop to take the user input until the person types e- Save and Quit

4. The options

a. Print the Phone List

prints the entire list to standard output

b. Add a Person

Prompts the user for the: last name, first name, phone number, and address

and Adds the person to the linked list in the correct location

c. Delete a Person

Asks the user for the last and first name.

If they exist: deletes the entry and prints a message stating the person was removed

If they dont exist: prints an error message

d. Find a Person

Asks the user for the last name only

Prints the matching people to the screen if they are found in the book

Prints a message saying could not find that person if no person in the book exists

e. Save And Quit

Saves the entire linked list to a binary file called phonedatabase.bin

5. Subsequent Program Starts Any other time you start the program, you should read the binary file phonedatabase.bin that was last saved to restore your phonebook.

6. Your program should then continue from step 4 displaying a menu of options to the user.

This is the addresses.csv (CVS file)

This is what I have so far for the phonebook.c (still needs some adjustments but file function code (from last assignment) seems to be similar to what I need in order to accomplish getting into file, reading and closing and I hope it helps).

#include

#include

#include

#define MAX_FIRST_PERSON_NAME 30

#define MAX_LAST_PERSON_NAME 30

#define MAX_ADDRESS 50

#define MAX_PHONE_NUMBER 20

char readAddresses(char * filename, Person names[], Person lastnames[], Person address[], Person phone[])

{

FILE * rfp; // this is our object to read data

char line[MAX_PERSON_NAME]; // Just make a buffer big enough to hold most data

char *token; // this is to help us 'parse' the data in the file

int i; // this is our loop variable

rfp = fopen(filename, "r"); //TODO: set your mode !!!

//TODO: You should tell the user that if n > 100 (the size of our hero array) then we will

// have a problem

fgets(line, MAX_LINE_SIZE, rfp); // skip the column names

i=0;

while (feof(rfp) == 0) //TODO: loop for n - times - create this - MAKE SURE YOU PAY ATTENTION TO MAX HEROS

{

fgets(line, MAX_LINE_SIZE, rfp); // read the line from the file

// so we can 'parse' the data out into

// our structure super hero

token = strtok(line, ","); // start by using strtok to break up the line

strcpy(heroes[i].name, token); // copy the name first.

//TODO: Fix the properties

token = strtok(NULL, ","); // health

heroes[i].health = atof(token); // this converts the string into a number for us.

// atof - ASCII to Float (double)

token = strtok(NULL, ","); // strength?

heroes[i].strength = atof(token);

token = strtok(NULL, ","); // charisma?

heroes[i].charisma = atof(token);

token = strtok(NULL, ","); // intelligence?

heroes[i].intelligence = atof(token);

i++;

}

fclose(rfp); // we are done reading, so close the file now so we don't hold it open

// so that other people/programs cannot use it...

// return the total number of heros we read -

// notice we use a tertiary logical operator that is

// condition ? VALUE IF TRUE : VALUE IF FALSE

// this could be re-written as:

// if (n > maxHeroes) return maxHeroes;

// else return n;

return i - 1;
