runtime error

#2

@ayu2321, you are getting run time error because you are inserting incorrectly, as you have not correctly handled the case when head is NULL
it should be

if(head == NULL){
    node*n = new node(data);
    head=n;  // you did'nt change head value
    return;
}

Also , your print function is wrong , it should be

void print(node*head,int n){
    for(int i=0;i<n;i++){
        cout<<head->data<<" ";
        head=head->next; // you forgot this
    }
}

In case of any doubt feel free to ask :slight_smile:
