Display Nodes of Linked List using Recursion
Write a C Program to Display Nodes of Linked List using Recursion. Here’s simple Program to Display Nodes of Linked List using Recursion in C Programming Language.
Recursion : :
- Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.
- The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
- Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.
Problem : :
This C Program uses recursive function & displays a linked list. A linked list is an ordered set of data elements, each containing a link to its successor.
Here is the source code of the C Program to Display Nodes of Linked List using Recursion. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.
SOURCE CODE : :
/* C Program to Display Nodes of Linked List using Recursion */ #include <stdio.h> #include <stdlib.h> struct node { int a; struct node *next; }; void generate(struct node **,int size); void display(struct node*); void delete(struct node **); int main() { int size; struct node *head = NULL; printf("Enter size of linked list to generate :: "); scanf("%d",&size); generate(&head,size); printf("\nThe Linked List Generated is :: \n\n"); display(head); printf("\n\n...........Deleting all nodes of the Generated Linked List.......\n"); delete(&head); printf("\nDeletion of all nodes of Linked List is successful !!!!\n"); return 0; } void generate(struct node **head,int size) { int i; struct node *temp; for (i = 0; i < size; i++) { temp = (struct node *)malloc(sizeof(struct node)); temp->a = i; if (*head == NULL) { *head = temp; (*head)->next = NULL; } else { temp->next = *head; *head = temp; } } } void display(struct node *head) { printf("%d ", head->a); if (head->next == NULL) { return; } display(head->next); } void delete(struct node **head) { struct node *temp; while (*head != NULL) { temp = *head; *head = (*head)->next; free(temp); } }
Output : :
/* C Program to Display Nodes of Linked List using Recursion */ Enter size of linked list to generate :: 10 The Linked List Generated is :: 9 8 7 6 5 4 3 2 1 0 ...........Deleting all nodes of the Generated Linked List....... Deletion of all nodes of Linked List is successful !!!! Process returned 0
Above is the source code for C Program to Display Nodes of Linked List using Recursion which is successfully compiled and run on Windows System.The Output of the program is shown above .
