  • C++ Pointers

    Trying to understand a program containing structures and pointers. I find pointers difficult to understand.

    Here is a piece of a program I am studying. The parts that confuse me i placed in bold. The two items on bottom I assume refer to functions and are passing pointers but i dont understand the "NODE*" part and i cant seem to find a reference anywhere like it. And of course the other bold selected in the struct.

    Code:
    struct Node
    {
    	char fname[NAME_SIZE];
    	char lname[NAME_SIZE];
    	char ssn[SSN_SIZE];
    	Node* next;
    };
    void searchNode(Node*,char*);
    Node* buildList(void);
    Node* insertNode(Node*,Node*);
    ALSO:
    To make sure I am also understanding this.
    Am i right in assuming this is initializing to value 0?
    Code:
    Node* head=(Node*)0;
    Can someone explain it to me?

    The "Node*" in front of each of the function definitions says that they will be returning a pointer to a Node structure.

    And yes, initializing to zero, or maybe more accurately the address zero.

      Understand C++ Pointers

      Use of pointers requires far more than syntax understanding. Requires expertise only time will give you.


      This explanation, pretty simple
