    int value
    node* next

    can i use func( node *root) here in order to change the value integer
    or func( node **root)

    I wonder, how it came that having more than 1000 posts you still cannot write a questing to be understand by others?

    if you have a struct
    Code:
    struct node
    {
       int value;
       struct node* next;
    };
    to change a value enough to pass pointer to struct

    void func(struct node* current);

    except for the problem of too many layers of indirection.

    If you know better, why do you still ask questions? Stop spamming
