The answer is they have been part of the C/C++ language and so we have to use it. Using pointer we can pass argument to the functions. Generally we pass them by value as a copy. So we cannot change them. But if we pass argument using pointer, we can modify them. To understand ab...
The last node of the list contains the address of the first node of the list. The first node of the list also contains the address of the last node in its previous pointer. Implementation: C++ #include <bits/stdc++.h> using namespace std; class Node { public: int data; Node* next...
Each node in a singly linked list has a pointer to the next node in the list. This permits rapid traversal in the forward direction only. In a single linked list getting the previous element is quite difficult and requires iterating through from the head making backwards traversal an O(n) ...
the pointer is not automatically handled; you have to get memory for it first. typically you have a load of functions to assist in using your list, like insert, delete all, delete 1, copy, whatever. here you need Node x; x.data = ..; ...
insertions in the middle are expensives XOR Double linked list A double linked list that only uses one pointer per node to go to the previous or next node. A bitwise XOR operation is applied on the node address field when inserting and reading; by this way, the list can find the next...
To insert a node into a linked list two essential parameters are needed: the data element of the new node and its position in the linked list. First, a pointer to the new_nodeis created using the NODE structure and its data element is assigned the value as given by the user. Next, ...

First things first, instead of using a single global variable, use a class to encapsulate the data structure.class Stack { public: Stack() = default; Stack(const Stack&) = delete; Stack& operator=(const Stack&) = delete; ~Stack(); void push(int data); void pop(); void display() ...
