Concept explainers
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
List head:
List head is a pointer used to point the first node in the linked list and it is also called as “head pointer”; if the “head pointer” points to a “NULL” value, then it is considered that the “list is empty”.
Graphical representation of linked list:
The graphical representation of a linked list is as follows:
Traversing the list:
Traversing the linked list is the process of visiting the list until reaching the last node. It is one of the operations in the list, which is used to visit each node exactly once in order to access the data stored in the list.
Steps to traversing a list:
The following steps are used to perform the traversing operation in a list.
Step 1: Move to the list head (first node).
Step 2: Retrieve the data from the head node and perform the necessary operation.
Step 3: After performing operation, move the pointer to next node and perform the operation until the end of the node.
Step 4: Perform all the above travelling nodes as a visited node.
Usage of traversing the list:
Print the elements.
- Traversing the list used to display all elements from the list.
Count the elements.
- Traversing the list used to count the number of elements available in the list.
Search the element.
- Traversing the list used to search a particular value in the list.

Write a function named addNode that takes in a variable of type int and inserts it at the head of the list. b. Write a function named removeNode that removes a node at the head of the list.arrow_forwardC Language In a linear linked list, write a function named changeFirstAndLast that swaps the node at the end of the list and the node at the beginning of the list. The function will take a list as a parameter and return the updated list.arrow_forward

Print the values separated by a [space]->[space] In the main function, write a program that asks the user to input five integers and assign these values to the nodes. Arrange the nodes in ascending order first before printing them using the printNodes function. Input 1. One line containing an integer 2. One line containing an integer 3. One line containing an integer 4. One line containing an integer 5. One line containing an integer Output Enter·number·1:·1 Enter·number·2:·2 Enter·number·3:·3 Enter·number·4:·4 Enter·number·5:·5 1·->·2·->·3·->·4·->·5arrow_forwardTrue or false?

- In Data Structure write down the useful operations performed on list? Also write the list operations performed on “current” marker/pointer.arrow_forwardstruct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.
