Unexpected #ifndef, No Matching Function Call (Linked List C++)

Hi i am currently working on a linked list project but am receiving a few errors while doing so that I can't seem to solve. The first error i am getting is an undetermined #ifndef. What im confused about is that I didnt #include a source file in the header.

My second error I am getting is in my main.cpp, where I am getting an error saying " no matching function call to 'List::AddNode(double, double, double,etc)".

I have posted all three of my files in hopes of someone helping me figure out these errors I am receiving, Thank You.

EDIT: Thank you for those who helped me, that has solved my problem but now I am receiving new errors saying
"undefined reference to List::List()',

undefined reference to List::AddNode(double, double, double, double, double, double, double, double)',

undefined reference to `List::PrintList()'".

Main

#include <iostream>
#include <cstdlib>
#include "List.h"

using namespace std;

int main()
{
    List Moe;

    Moe.AddNode(23.00, 7.00, 12.75, 7.65, 1.00,45.00, 0.18, 50.00);
    Moe.PrintList();
}

Solution

You misunderstood the way header guards are used: you need a conditional compile statement to guard the entire content of the header, not just the #define. Move #endif to the end of the file, and remove or comment out LIST_H_INCLUDED at the end:

#ifndef LIST_H_INCLUDED
#define LIST_H_INCLUDED

using namespace std;
class List
{
private:

    struct node{
        double adults, children,costA,costC,dessert,room,tt,deposit;
        node* next, *link;

    };
    typedef struct node* nodePtr;

    nodePtr head;
    nodePtr curr;
    nodePtr temp;

public:
    List();
    void AddNode(double addAdults,double addChildren, double addCostA, double addCostC,double addDessert, double addRoom, double addTT, double addDeposit);
    void PrintList();
};

#endif /* LIST_H_INCLUDED */
