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 });             }            

LINQ Standard Query Operators in ASP.NET

The standard query operators are the methods that form the LINQ pattern. The standard query operators provide query capabilities including filtering, projection, aggregation, sorting, and much more. The standard query operator in LINQ is an Application Programming Interface (API) that enables querying of any .NET array or collection. You can use these standard query operators to operate on sequence.

The following are two set of standard query operators in LINQ:

1.  The first type is the one that operates on objects of the type IEnumerable<T>.
2.  The second one is the one that operates on object of the type IQueryable<T>.

The standard query operators differ in the time that they take for their execution. The time depends on whether they have to return a single value or a sequence of values. The methods that return a single value execute immediately. The methods that return a sequence of values reschedule the query execution and return an enumerable object.

List of all Query operators are:

Filtering Operator: Restricts the result set to contain those elements that satisfy a specific condition that are
returned
Projection Operator: Transforms an object into a different type of new object
Sorting Operator:  Changes the order of elements of sequence returned by the query
Join Operator: Combines collections
Grouping Operator: Puts the data into groups
Quantifier Operator: Checks whether an element of a sequence satisfies a condition
Partitioning Operator: Returns a subset of collection
Set Operator:  Returns a result set which is in the form of a collection
Element Operator:  Returns just one element
Aggregate Operator:  Computes a single value from a collection
Conversion Operator: Converts the collection to an array
Generation Operator: Returns a new sequence of values

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
