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 });             }            

Program to find sum of even and odd numbers (using one for loop) in C

Instead of using two for loops as in the previous program, only one for loop can be used. Let us see how this can be achieved.

sum= 0;
/* To add all numbers */
for(i=1; i<=n; i++)
{
sum = sum+i;
}

It is easy to say that we are computing the sum of all the numbers from 1 to n. To add only even numbers or to add numbers, the code can be changed as shown below:

esum=0;                          /* To store sum of even numbers */
osum = 0;                        /* To store sum of odd numbers */

/* To generate the integer from 1 to n */

for(i=1; i<=n; i++)
{
if(i % 2 == 0)                     /* If even */
esum = esum + i;               /* Add to even sum */
else
osum = osum + i;

}

Thus, after the control comes out of the for-loop, the variable esum contains the sum of even numbers and the variable osum contains the sum of odd numbers. The result can be printed using the following statements:

printf("Sum of even numbers = %d\n",esum);
printf("Sum of odd numbers = %d\n", osum);

The complete program is shown below:

Example : Program to add even numbers and odd numbers.
Program
#include<stdio.h>
main( )
{
int n, i, esum, osum;
printf("Enter the value of n:\n");
scanf("%d",&n);
/* Generate and print number from 1 to n */
printf("Integer from 1 to %d are \n",n);
for(i=1; i<=n;i++)
printf("%d",i);
printf("\n");
esum=0;
osum=0;

/* find sum of even and odd numbers */
for ( i=1; i<=n; i++)
{
if((i %2) == 0)
esum +=i;     /* Add even numbers */
else
osum += i;    /* Add odd numbers */

}
printf(" Sum of even numbers = %d\n",esum);
printf("Sum of odd numbers = %d\n",osum);
}

Execution starts from here

Non-executable statement
Input
Enter the value of n:
6
Output 1
Integer from 1 to 6
1 2 3 4 5 6

Computations
e_sum = 0
o_sum = 0

i=1 2 3 4 5 6
e_sum = 0+2+4+6
                         = 12
o_sum= 0+1+3+5
                         = 9
Output 2

Sum of even numbers =12
Sum of odd numbers = 9

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
