DLLs using LoadLibrary()

[Wynd]

I am trying to write a DLL and call a function in it using LoadLibrary and GetProcAddress(). The code compiles fine, and I can enter two numbers, but then it crashes. This is my code:

//Main program
#include <iostream>
using namespace std;
#include <windows.h>

typedef void (__stdcall* MYFUNCTION)(int, int, int &);

int main()
{
	HINSTANCE hDLL;
	MYFUNCTION funcAdd;
	int x, y, sum;

	hDLL = LoadLibrary("dll.dll"); 

	if (hDLL)
	{
		funcAdd = (MYFUNCTION)GetProcAddress(hDLL, "funcAdd");

		cout << "Enter 2 ints:" << endl;
		cin >> x >> y;
		(funcAdd)(x, y, sum);// call the function
		cout << "The sum is " << sum << endl;

		FreeLibrary(hDLL);
	}
	cin.get();
	return 0;
}

//DLL code
void __stdcall __declspec(dllexport) funcAdd(int a, int b, int &c)
{
    c = a + b;
}

Any ideas?
