Why am I getting error LINK2019 and LINK1120?

[MisterTams]

Every time I try to run this code I get those two errors. I don't see any missing semi-colons or anything? There are no other errors besides those two so I don't know what's going on. My math calculations might be wrong and I can't even compile to check how the program runs! Please help.

#include <iostream>
#include <iomanip>
#include <vector>
#include <algorithm>
using namespace std;

//function prototype
double MedianF (int *, int);
void arraySort (int *, int);

int main ()
{
	int *MyArray = nullptr;
	int elements;
	double MEDIAN;

	cout << "How many elements?" << endl;
	cin >> elements;

	MyArray = new int[elements];

	MEDIAN = MedianF (MyArray, elements);

	cout << "The median is..." << MEDIAN << endl;

	delete [] MyArray;
	MyArray = nullptr;

	system("pause");
	return 0;
}

double Median (int *Array, int Elem)
{
	 double median = 0.0;
 
    // First of all, sort our numbers.
    arraySort(Array, Elem);

    int mid = 0;
 
    // If array is even number of elements, find the middle element
    // Size of array split in 2, since it is converted to int, it drops fraction
    // subtract 1 because array is zero index.

    if((Elem % 2) == 0)
    {
        mid = (Elem / 2) - 1;
        median = (Array[mid] + Array[mid + 1]) / 2;
    }
    else
    {
        // If array is odd, find middle term by dividing in half, let it drop
        // the fraction when casting ot int. Use middle point to get value.
        mid = (int)(Elem / 2);
        median = Array[mid];
    }
    return median;

}

void arraySort (int *Array1, int Elem1)
{
	int startScan;
    int minIndex;
    int minElem;
 
    for (startScan = 0; startScan < (Elem1 - 1); startScan++)
    {
        minIndex = startScan;
        minElem = *(Array1 + startScan);
        for (int index = startScan + 1; index < Elem1; index++)
        {
            if ((*(Array1 + index)) < minElem)
            {
                minElem = *(Array1 + index);
                minIndex = index;
			}
        }

        *(Array1 + minIndex) = *(Array1 + startScan);
        *(Array1 + startScan) = minElem;
    }
}

Please copy and paste the errors here; just stating the error number isn't much help.

firedraco,

Where is the function MedianF defined in the OP? There is a function definition that is similar in name: Median... but that's not MedianF, is it?

cire,

Thanks. I missed that when I was checking.

Thanks again,
