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 });             }            

Integer Constant in C language

Integer constant 

‘‘What is an integer? Explain giving example.”

Definition: An integer constant is a whole number without any decimal point. No extra characters are allowed other than + and –sign. If + and – are present, they should precede the  number. An integer constant can be classified into three types as shown below.

Integer Constants are

Decimal : e.g: 120,14,-1, etc
Octal   : e.g : 070,012,-040, etc.
Hexadecimal : e.g. 0xBA, 0x3B etc


Now, let us explain decimal integer with example.
Definition: A decimal integer can be any combination of digits from ‘0’ to ‘9’. No extra characters are allowed other than ‘+’ and ‘–’ sign. If ‘+’ and ‘–’are present. Then they should precede the integer. For example, 100,-7,+989 etc.The following are invalid:


Decimal Integers
Validity
Reasons for Invalidity
10,000
invalid
Comma is not allowed.
0.5
invalid
Decimal point is not allowed.
10 20
invalid
Space is not allowed.
085
invalid
Should not start with the digit 0.
32768
invalid
Out of range for 16 bit machine.
-32769
invalid
Out of range for 16 bit machine.

Now let us see ‘‘What is an octal number? Explain giving example.’’

Definition: An octal integer constant can be any combination of digits from ‘0’ to ‘7’ with a Prefix 0(digit zero).No extra characters are allowed other than preceding ‘+’ and ‘- ’ sign. For Example, 01612, 034567, -0765 etc. are valid. The following are invalid:

Octal Integers
Validity
Reasons for invalidity
7,000
Invalid
Comma is not allowed.
0.075
Invalid
Decimal point is not allowed.
10 20
Invalid
Space is not allowed.
085
Invalid
8 is invalid in octal.
275
Invalid
Should have a prefix 0.



Now, let us see ‘‘What is a hexadecimal number? Explain giving example.’’

Definition: An hexadecimal integer constant can be any combination of digits from ‘0’ to ‘9’ along with the letters ‘A’ to ‘F’ or ‘a’ to ‘f’. This constant has be preceded OX or OX. For example, 0x18A, OXB, OXFFF etc. are valid. The following are invalid hexadecimal constant:

Hexadecimal Integers
Validity
Reasons for invalidity
10,000
invalid
Comma is not allowed.
0xIJ
invalid
I and J are invalid characters.
Ox123
invalid
Should be preceded with 0(zero) not O(Oh.)
O1234
invalid
Should be preceded with 0x or OX.




Note: usually decimal integers are used in programming. Octal and hexadecimal  are rarely used.
Floating point constant

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
