How to Find Length of a Linked List?
Length of Linked List using Iterative Approach
Length of Linked List using Recursive Solution
Iterative C program to find length or count of nodes in a linked list

Iterative Solution
1) Initialize count as 0
2) Initialize a node pointer, current = head.
3) Do following while current is not NULL
a) current = current - next
b) count = count+1;
4) Return count

We will use the Linked list traversal to find the length of a linked list.

Head Points to the First Node of The List.
Initialize the count variable with value 0
Initialize the temp variable with Head
As we access each Node, the value of count variable is increased by 1.
Stop The process when we reach null.
Do not change the head reference.

Recursive Solution
int getCount(head)
1) If head is NULL, return 0.
2) Else return 1 + getCount(head-next)

Base Case:
Last Node points to Null value
Return 0
Recursive Case:
At each step update the Value of Current Node to the Next Node
