Write the functions that will add print and delete a bank re

Write the functions that will add, print, and delete a bank record. The program will be written in C

These are the protoypes for the functions:

- int addRecord (struct record **, int, char [ ],char [ ],int);

- struct record ** is the pointer to the pointer to the start of the record, passed in main.

- struct record *start = NULL will be defined in main

- the second int will pass an account number

- char[] will pass the name of the user

- the second char[] will pass the address of the user

- the last int will pass the year of birth of the user

- THIS FUNCTION WILL ADD THE RECORDS IN ORDER OF THE YEAR OF BIRTH, YOUNGEST TO OLDEST

- e.g. an account with a YoB 1990 will come before a record with 1980.

- If there is a duplicate account (Same account number), it will still be made, but ordered in the birthyear

- if the birth year is the same, the new account will be added after the old account

- int printRecord (struct record *, int);

- int will pass the account number of the record that needs to be printed

- int deleteRecord(struct record **, int);

   - int will pass the account number of the record that needs to be printed

- this function will delete the entire record for that account number

This header file will be provided:

struct record
{
    int              accountno;
    char             name[25];
    char             address[80];
    int              yearofbirth;
    struct record*  next;

};

None of the information on top can be changed. Thank you in advance for the help!
