What is far and near pointer and how are they used?
It is a matter of the memory model you are using. On old or embedded systems, some memory was outside of the range of a normal pointer. If you have 4 megs of ram you need at least a 22bit pointer to see all of it. But let's say you only have a 16 bit pointer. This means you can only access the first 65K of ram. Odd as it may sound, this was a problem on old computers, and is sometimes an issue on embedded devices with limited processing power. The near and far classifications were a solution. Pointers are near by default. In my example above, the 65K of ram would be accessed with a near pointer. To get past that 16 bit limit, you need a far pointer. Thus: memory within the pointer's range is near. Memory outside of the range is far. Near pointer: char near * ptr; Far pointer: char far * ptr;A far pointer uses both the segment and the offset address to point to a location in memory. A near pointer in contrast uses only the offset address and the default segment. The far pointer can point to any location in memory, whereas the near pointer can only point to a nearby local address.Something that was important 20 years ago. Now you can forget it.
Implement a queue using a singly linked list l the operations insert and delete should still take o1time?
Suppose we have a Queue as follows: E -> D -> C -> B We maintain a head pointer to E and a tail pointer to B. To add an element, we make a new queue item (say A), we set B->next = A, and set tail = A. To delete an element, we let a temp pointer to the head (say tempHead = head), set head = E->next and deallocate tempHead.
When destructor can be virtual in c plus plus?
A class constructor initialises object member variables, ensuring the object is in a valid state from the point of instantiation. The destructor resets those same variables when the object falls from scope. Typically, the destructor is only required to release any memory allocated to any internal class pointers.
What is the algorithm to delete a child node in binary tree?
as far as i know u have 4 cases for the node u wanna delete1.It's a leaf (has no children)2.It has only left child3.it has only right child4.it has both children ,left and rightnow, let's work on it :>set a pointer node to the rootwhile the element to be deleted doesnt equal the pointerif it's smaller, move the pointer to the left subtreeif it's large , move the pointer to the right subtreeif pointer reached the end of the tree , null, break the loop (unluckly that means u didnt find the element that should be removed)end while //(now u must have found the target, the while condition is breaked normally)// this is case 4if both children don't equal nullget the most left node in the subtree of the pointer nodeassign its value to the pointer node.remove it (set that most left thing to equal null)//...case 2if pointer node.right only equals nullpointer node = pointer node.left//...case3if pointer node.left only equals nullpointer node = pointer node.right//... case 1if pointer node.left and .right equals nullpointer node.data = nullmaybe it doesnt look like any algorithm style ,sorry for that, that's as far as i knw, i doubt case 4 anyways..
Circular queue in linear data structure?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.
