Here is the solution to this incomplete code

void addIntToEndOfList(LinkedList *list,int value)
{
assert(list!=NULL);
Node *p;
Node *head;
Node *tail;
node *newnode = (node*)malloc(sizeof(node));
p->newnode;

p->value = val;

p->next = NULL;

if(list->head == NULL)
{
head-> p;
tail->p;
}
else
{
node *current = head;
while(current->next != NULL)
{
if(current->next == NULL)
{
current->next = p;
printf(” p node added at the end of the list”);
}
current = current->next;
}
}
}
