Could someone please help me with this [ C programming, Linked List]

here is the question that i have to answer..

Write a C program that asks the user to enter items until the user chooses to stop, stores them into list nodes, and chains the nodes together into a linked list.  You will need to make the following changes:

•	Your linked list should store information about Customers’ Transactions that contain three fields: customer name (string), customer number (int), and transaction description (string).  
•	Instead of putting all of your code inside the main source code file, you should create the following functions:
o	addToStart()
o	addToEnd()
o	printList()
o	removeNodeAt()
•	Instead of simply asking the user if they want to add a new node, your main program should offer the user a menu of options:
o	Add a new node to the end
o	Add a new node to the beginning
o	Print out the entire list
o	Remove a node from the list
o	Quit the program
