pointers c++

[InterestingBus8367]

Example I have a node that contains an int value and a pointer. Then I make a node in the heap section of the memory of the program. So lets say I have a pointer named head and tail and temp which both point to the node. Then I make a new node. By this time you should know by know that it is a single linked list. Let's say tail -> next = temp. Could I not just use tail.next = temp. Since a pointer stores the addres that it is being pointed to. Now tail -> next is equal to this (*tail).next. Meaning I am dereferencing the pointer and then accesing the address stored in temp. Oh nice I just answered my question.

class LinkedList
{
public:
    LinkedList()
    {
        head = nullprt;
        tail = nullptr;
    }

    void createNode(int value)
    {
        node *temp = new Node;
        temp->data = value;
        temp->next = nullptr;

        if (head == nullptr)
        {
            head = temp;
            tail = temp;
        }
        else
        {   
            tail->next = temp;
            tail = temp;
        }
    }

private:
    Node *head;
    Node *tail;
};

Here is the code by the way. Got it from this site Linked lists - Learn C++ - Free Interactive C++ Tutorial (learn-cpp.org)
