C adding node to head of linked list

Question

I have created a linked list struct in c

struct node{
   int value;
   struct node* next;
};

a method to add a node at the start of the list :

Answer 1

void addFirst(struct node **list, int value){
    struct node *new_node = (struct node*) malloc (sizeof (struct node));
    new_node->value = value;
    new_node->next = *list;
    *list = new_node;
}

This is the correct code. the problem is that the poineter struct node *list You are passing can't be changed as it is a stack variable. If you change it to struct node **list you are passing a pointer to the first node of the list. now you can change that to point to the new first node of the list.
