Count number of nodes in a linked list that may be circular

WebCounting nodes in a linked list is very useful while working on it. It requires creating a temp node pointing to the head of the list and a variable called i with initial value 0. If the temp node is not null, increase i by 1 and move to the next node using temp next. Repeat the process till the temp node becomes null. WebMay 15, 2024 · In the below program, we are implementing a singly linked list as a circular linked list to calculate the count of nodes in that.

Every linked list has two parts, the data section and the address section that holds the address of the next element in the list, which is called a node. The size of the linked list is not fixed, and data items can be added at any locations in the list. WebcountNodes () will count the number of nodes present in the list. Define a variable counter and new node current which will point to the head node. Traverse through the list to count the nodes by making the current node to point to next node in the list till current point to null.
