How to implement a linked list in C?

Question

I am creating a linked list as in the previous question I asked. I have found that the best way to develop the linked list is to have the head and tail in another structure.

Answer 1

#include 
struct node
 {
  int data;
  struct node* next;
 };

int main()
{

//create pointer node for every new element

struct node* head = NULL;
struct node* second = NULL;
struct node* third = NULL;

//initialize every new pointer with same structure memory

head = malloc(sizeof(struct node));
second = malloc(sizeof(struct node));
third = malloc(sizeof(struct node));

head->data = 18;
head->next = second;

second->data = 20;
second->next = third;


third->data = 31;
third->next = NULL;

//print the linked list just increment by address 

  for (int i = 0; i < 3; ++i)
    {
      printf("%d\n",head->data++);
      return 0;
    }
 }

This is a simple way to understand how does pointer work with the pointer. Here you need to just create pointer increment with new node so we can make it as an automatic.
