changing parameter of a function..

if i have a root in the signature of a function what has
int value
node* next
in it

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);

but it changes the value of the parameter
we need **

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

i know that we cant change the parameter thats why we use

** root

so we use it when we what to change the address of the root
