Working on Josephus problem, Node function not working

Question

I'm working on an assignment based on the Josephus problem and circular linked lists. The function below gives an error in Xcode (Control reaches end of non-void function) which I assume means that I need a return statement. However, when I add one, it doesn't accept it. But when I try the code in online compilers it works fine.

Node *newNode(int data)
{
    Node *temp = new Node;
    temp->next = temp;
    temp->data = data;
}

Answer 1

You need to add return temp; at the end:

Node *newNode(int data)
{
    Node *temp = new Node;
    temp->next = temp;
    temp->data = data;
    return temp;
}
