Self referential structure in c programming

Exploring Self-Referential Structures in C Programming

A self-referential structure in C is a structure that contains a pointer to itself. This allows the structure to refer to itself, creating a linked data structure. Self-referential structures are a powerful tool for creating complex data structures in C++ and are commonly used in algorithms such as trees, graphs, and linked lists.

Here is an example of a self-referential structure in C:

C programming

This structure has one member, data, which stores the value of the node. It also has a pointer member, next, which points to the next node in the linked list.

To create a linked list, we can use the following code:

Node *head = NULL;

// Create a new node
Node *newNode = malloc(sizeof(Node));
newNode->data = 10;
newNode->next = NULL;

// Add the new node to the linked list
head = newNode;

We can then add more nodes to the linked list by using the next pointer to connect them together. For example:

// Create another new node
Node *newNode2 = malloc(sizeof(Node));
newNode2->data = 20;
newNode2->next = NULL;

// Connect the first and second nodes
head->next = newNode2;

To print the linked list, we can use the following code:

Node *current = head;
while (current != NULL) {
  printf("%d ", current->data);
  current = current->next;
}

This code will print the following output:

10 20

Self-referential structures can be used to create a variety of complex data structures, such as trees, graphs, and stacks. They are a powerful tool for C programmers and are used in many popular algorithms.
