This is C. Below is my code i am still running into some errors as well i will post below

(1) Create three files to submit.

Contacts.h - Struct definition, including the data members and related function declarations

Contacts.c - Related function definitions

main.c - main() function

(2) Build the ContactNode struct per the following specifications:

Data members

char contactName[50]

char contactPhoneNum[50]

struct ContactNode* nextNodePtr

Related functions

CreateContactNode() (2 pt)

InsertContactAfter() (2 pts)

Insert a new node after node

GetNextContact() (1 pt)

Return location pointed by nextNodePtr

PrintContactNode()

Ex. of PrintContactNode() output:

Name: Roxanne Hughes Phone number: 443-555-2864 

(3) In main(), prompt the user for three contacts and output the user's input. Create three ContactNodes and use the nodes to build a linked list. (2 pts) Ex:

Person 1 Enter name: Roxanne Hughes Enter phone number: 443-555-2864 You entered: Roxanne Hughes, 443-555-2864 Person 2 Enter name: Juan Alberto Jr. Enter phone number: 410-555-9385 You entered: Juan Alberto Jr., 410-555-9385 Person 3 Enter name: Rachel Phillips Enter phone number: 310-555-6610 You entered: Rachel Phillips, 310-555-6610 

(4) Output the linked list. (2 pts) Ex:

CONTACT LIST Name: Roxanne Hughes Phone number: 443-555-2864 Name: Juan Alberto Jr. Phone number: 410-555-9385 Name: Rachel Phillips Phone number: 310-555-6610

1. Unit test Tests that CreateContactNode() initializes a node with name "Jane Doe" and phone number "555-555-5555. 2.
