Answer 1

Correct code,

void insertion(struct Node *node,int data){
if(node->next==NULL and node->data != 0){
Node *temp = new Node();
temp->data = data;
node->next = temp;
}else if(node->next == 0 and node->data == 0 ){
node->data = data;
}
}

void traverse(struct Node *head){
while(head){
cout<<head->data;
head = head->next;
};
}

to get rid of warning i replaced NULL with 0 .

Answer 2

these are some of the mistakes you are making.

struct Node{
int data;
Node *next;
};

void insertion(Node *node, int data){

void traverse(Node *head){

if(node->next == NULL && node->data != 0) {

} else if(node->next == 0 && node->data == 0 ){
