Reading input from a text file, omits the first and adds a nonsense value to the end?

When I input locations from a txt file I am getting a peculiar error where it seems to miss off the first entry, yet add a garbage entry to the end of the link list (it is designed to take the name, latitude and longitude for each location you will notice). I imagine this to be an issue with where it starts collecting the inputs and where it stops but I cant find the error!! It reads the first line correctly but then skips to the next before adding it because during testing for the bug it had no record of the first location Lisbon though whilst stepping into the method call it was reading it. Very bizarre but hopefully someone knows the issue. Here is firstly my header file:

#include <string>

struct locationNode
{
    char nodeCityName [35];
    double nodeLati;
    double nodeLongi;

    locationNode* Next;



void CorrectCase() // Correct upper and lower case letters of input
    {

        int MAX_SIZE = 35;
        int firstLetVal = this->nodeCityName[0], letVal;
        int n = 1; // variable for name index from second letter onwards


        if((this->nodeCityName[0] >90) && (this->nodeCityName[0] < 123)) // First letter is lower case
        { 
             firstLetVal = firstLetVal - 32; // Capitalise first letter
             this->nodeCityName[0] = firstLetVal;
        }

        while(n <= MAX_SIZE - 1)
        {
            if((this->nodeCityName[n] >= 65) && (this->nodeCityName[n] <= 90))
            {
                letVal = this->nodeCityName[n] + 32;
                this->nodeCityName[n] = letVal;
            }
            n++;
        }
        //cityNameInput = this->nodeCityName;
    }

};



class Locations
{
private:
    int size;

public:

    Locations(){

    }; // constructor for the class

    locationNode* Head;

    //int Add(locationNode* Item);

The text file contains this (ignore the names, they are just for testing!!):

Lisbon 45 47
Fattah 45 47
Darius 42 49
Peter 45 27
Sarah 85 97
Michelle 45 47
John 25 67
Colin 35 87
Shiron 40 57
George 34 45
Sean 22 33

The output omits Lisbon, but adds on a garbage entry with nonsense values. Any ideas why? Thank you in advance.

The main function creates a new locationNode and stores it in the global variable temp, then reads the first dataset and stores it in that node.

Then you call addLocation() which starts by creating another new locationNode which replaces the existing one in temp. This new node is then inserted into the list.

The next iteration of the main loop then fills that temp value with values and addLocation() inserts another brand new locationNode into the list. So the first dataset isn't stored in the list and each iteration ends up by inserting an uninitialized new node.

As you see using global variables can lead to confusing situations and you code would surely become clearer if you were passing the nodes as parameters to your functions.
