In this lab, you need to implement a simple linked list using dynamic memory allocation. The structure of node in the linked list has been declared in lab3.h. Also, the functions of linked list have been declared in lab3.h as well. In main.c, these functions are called. Your work is to finish these function implementations in a separate C source file, and create a makefile which can compile your separate C source file along with main.c and lab3.h.

You can follow the comments in main.c and lab3.h to finish this lab. Please do not change main.c and lab3.h, because your separate C source file will be compiled with these two files posted on BlackBoard. When you test your program, please put main.c, lab3.h, your separate C source file and your makefile in the same directory and compile.

Code provided:

lab3.h

#include #include #ifndef LAB3_H #define LAB3_H struct node { int data; struct node *next; }; struct node *init (); //initialize: create an empty head node (whose "data" is intentionally missing); This head node will not be used to store any data; void insert(struct node *head, int data); //Create a new node to store data and insert it to the end of current linked list; the head node will still be empty and data in the array in "main.c" are not stored in head node void display (struct node *head); //print data for all nodes in the linked list except the head node (which is empty) void deleteAll (struct node *head); //delete the entire linked list including the head node #endif 

main.c

#include"lab3.h" int main() { int array[]={1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; struct node *head; head = init(); //after this statement, a linked list has been created with only a head node int i; for (i=0;i<10;i++) { insert(head, array[i]); //create a new node to store an array element. This new node is inserted to the end of current linked list } display(head); //print data for all nodes in the linked list except the head node (which is empty) deleteAll(head); //delete the entire linked list including the head node return 1; }

This is needed to be coded in C.
