Write a void function that takes a linked list of integers and reverses th order of its nodes. The function will have one call-by-reference param that is a pointer to the head of the list. After the function called, this pointer will point to the head of a linked list that has the same nodes a the original list, but in the reverse of the order they had in the original Enter number of elements in linkedlist: 5

**Reversing a Linked List: Function Details**

This section describes how to write a void function that takes a linked list of integers and reverses the order of its nodes. The function uses a call-by-reference parameter, which is a pointer to the head of the list. After the function executes, this pointer will indicate the head of a linked list with the same nodes as the original, but in reverse order.

**Input Instructions and Example:**

- You are required to enter the number of elements in the linked list.
- For demonstration, here is an example with 5 elements:
  1. Enter the 1st element of the linked list: 34
  2. Enter the 2nd element of the linked list: 22
  3. Enter the 3rd element of the linked list: 51
  4. Enter the 4th element of the linked list: 76
  5. Enter the 5th element of the linked list: 13

**Output:**

- Given Linked List: 
  - The elements appear in the original order: 
    `34 -> 22 -> 51 -> 76 -> 13 -> NULL`

- Reversed Linked List:
  - The elements appear in the reversed order: 
    `13 -> 76 -> 51 -> 22 -> 34 -> NULL`

This example highlights the importance of linked list manipulation in computer science, particularly for applications requiring data order alterations without altering the data structure's integrity.
