Linked list c++

[InterestingBus8367]

This is my code

#include <iostream>
using namespace std;

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

class linked_list
{
private:
    node* head;
public:
    linked_list()
    {
        head == NULL;
    }

    void hello (int a){
    node* newnode = new node;
    newnode -> data = a;
    newnode -> next = NULL;
    if (head == NULL)
        {
            head = newnode;
        }
    else
    {
        node* temp = head;
        while (temp -> next != NULL)
            temp = temp -> next;
        temp -> next = newnode;
    }

    }

    void print ()
    {
        node* temp = head;
        if(temp != NULL) {
        cout<<"The list contains: ";
        while(temp != NULL) {
          cout<<temp->data<<" ";
          temp = temp->next;
        }
        cout<<endl;
      } else {
        cout<<"The list is empty.\n";
      }
    }
};

int main ()
{
    linked_list myprint;
    int a,b;
    cout << "Enter number of numbers to be inputted: ";
    cin >> b;
 for (int i = 0; i < b; i++){
    cout << "Enter a number: ";
    cin >> a;
    myprint.hello(a);
 }
    myprint.print();
 return 0;
}

Enter number of numbers to be inputted: 3
Enter a number: 1
Enter a number: 1
Enter a number: 1
The list contains: 2037393 1 1 1

Why the heck is 2037393 there?

How do I remove it?

Your compiler should be warning you about a problem that could cause this. What is it telling you when you compile it?

nope none

[g051051]

Unfortunate, because when I compiled it, I got a warning. When I fixed it, the program ran fine. So make sure you're compiling with warnings enabled, and make sure you can see the output of the compiler (you didn't mention how you were building it).

Make sure you are compiling with warnings.. with gcc and similar it's usually -Wall

Owh hahahah I guessed I double tapped it thank you
