C++ :: Search For Element By Name - Printing Linked List

I've got this program that I'm working on. Most of the code is from a video tutorial, but I was editing it to be able to search for an element by name. That's working fine, but suddenly the part of the program that prints out all the elements starts in an infinite loop after I input two elements, and search for one.

Here's what I've got:

[code#include <iostream> usingnamespacestd; struct node { int number; string name; node *next; }; bool isEmpty (node *head); char menu (); void insertAsFirstElement (node *&head, node *&last, int number); void insertSorted(node *&head, node *&last, int number); void remove(node *&head, node *&last); void showList (node *current); void showByName (node *current, string name); bool isEmpty (node *head) { if (head == NULL) { return true; } else { returnfalse; } } char menu () { char choice;
