How to use Tabs in ASP.NET CORE

I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component  public class AllViewComponent : ViewComponent     {         private readonly UserManager<ApplicationUser> _userManager;         public AllViewComponent(UserManager<ApplicationUser> userManager)         {             _userManager = userManager;         }         public async Task<IViewComponentResult> InvokeAsync()         {             List<StudentViewModel> allUsers = new List<StudentViewModel>();             var items = await _userManager.Users.ToListAsync();             foreach (var item in items)             {                 allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email });             }            

Linear Linked List for Data Structure in C language

  Linear Linked List

Creation:

           External pointer ROOT is used to store  the address of the first node of the Linked List. So initially when the list is empty the ROOT contains a NULL (0) address.

  
When the first node is created dynamically memory is allocated to it. The address of that first node is store in ROOT. Another pointer variable TEMP is also used to store the address of first node. The pointer variable TEMP is used to point every time to the current node created so that to store the address of first node all the
time.

 

            When next node is created, the LINK of the FIRST node is stored with its address. As TEMP points to FIRST node TEMP’s LINK field is copied with new node’s address and TEMP is updated to point to new node.



Similarly all the node are added to the linked list.

Algorithm to create a linear linked list.

      CREATELL
      ROOT<--  NULL
      CHOICE<--‘Y’
      Repeat While CHOICE=’Y’
        If AVAIL=NULL Then:
          Write:’Memory Allocation Error’; Exit.
        Else:
         NEW<-- AVAIL
         NEW--> LINK<-- NULL
         NEW--> INFO<-- Information
         [Information is the data to be stored in linked list]
         AVAIL<-- AVAIL--> LINK
       [End of it]
       If ROOT=NULL Then:
         ROOT<-- NEW
         TEMP<-- NEW
      Else:
        TEMP--> LINK<-- NEW
        TEMP<--  NEW
      [End of it]
      Write: ‘Do you want to add another node?(Y/N)’
      Read: CHOICE
  [End of while]
Exit.

C Program to create unordered Singly Linked List:
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
struct node
{
int info;
struct node *link;
};typedef struct node sn;
main()
{
 sn *root, *temp, *new; char choice=’y’;
 root=NULL;
 while(choice==’y’)
 {
 new=(sn*)malloc(sizeof(sn));
 if(new==NULL)
 {
 printf(“Memory allocation error…”); exir(0);
 }
 new->link=NULL;
 printf(“\nEnter node information :”);
 scanf(“%d”,&new->info);
 if(root==NULL)
 {
  root=new;      temp=root;
  }
else
 {
  temp->link=new;  temp=new;
 }
  printf(“Do you want to continue…(y/n)”);
  choice=getche();
 }
 printf(“\nThe Singly linked list is:\n\n”);
 temp=root;                /*temp pointer is reused */
 while(temp!=NULL)
 {
 printf(“%d”,temp->info);   temp=temp->link;
 }
}

Polynomial representation using Linked List for Data Structure in 'C'

Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also

Memory representation of Linked List Data Structures in C Language

                                 Memory representation of Linked List              In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.                Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:       Suppose next node is allocated at an address 506, so the list becomes,   Suppose next node is allocated with an address with an address 10,s the list become, The other way to represent the linked list is as shown below:  In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of
