Please help with this!! in c++!
![### Reversing a Singly-Linked List
#### Objective
Write a program `void reverse_list(list **l)` in pseudo-code or C++ to reverse the direction of a given singly-linked list. After the reversal, all pointers should point backwards. The algorithm should operate in linear time.
#### Node Structure
The node of this singly-linked list is defined as:
```c
typedef struct list {
item_type item;
struct list *next;
} list;
```
#### Function Definition
```c
void reverse_list(list **l) {
// Functionality to be filled in here
}
```
This educational example provides a guideline on how to approach reversing a singly-linked list in linear time using C++ or similar pseudo-code. The `list` structure consists of an item of unspecified type `item_type` and a pointer to the next node in the list. The `reverse_list` function is to be implemented to achieve the reversal of node links.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F02a699f1-d60c-495e-b821-a86bb0a104cb%2Fd4007e1c-bfa1-40f1-a8f4-efe7d148acba%2Fd10hqvl_processed.png&w=3840&q=75)
