(Summing and Averaging Elements in a List) Write a program that inserts 25 random integers from 0 to 100 in order in a linked list object. The program should calculate the sum of the elements and the floating-point average of the elements.
Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference)
int removeAt(int pos)
Removes the number in the posth position of the list and returns the element removed.
Performing removeAt(3) in the example list will remove the 3rd element of the linked list and the updated list will be: 10 -> 30 -> 50
When the value of pos is greater than the size or less than one, return -1.
int removeAll(int num)
Removes all instances of num in the linked list and returns the number of instances removed.
In this list 10 -> 10 -> 20 -> 30 -> 10, performing removeAll(10) will remove all three 10's and the list will look like this: 20 -> 30. Then, it will return the number of instances removed, in this case, 3.
int contains(int num)
This will return the position of the first instance of the element num in the list. If num is not found, return 0. In the example, having the method contains(30) will…

- Use c++ Write a program that uses the STL list container to create a linked list of integers. The program will ask the user to provide a list of integers. When the user is finished, the program will list the integers entered by the user and show the average of those integers. Additionally, you need to add the following code: Display your name (first and last) before you ask the user to enter the integers.

Performing addAt(20, 2) in the example list will add 20 at the 2nd position and the array will now look like this: [10, 20, 30, 40, 50] When the value of pos is greater than the size + 1 or less than one, output "Position value invalid" void removeAt(int pos) Removes the number in the posth position of the list.
