Thread: Pointer to function isn't exactly working

I have this code

Code:

#include <iostream>
#include <conio.h>

using namespace std;

double Area(double, double);

int main() {
double(*pArea)(double, double);
pArea = Area;
double Length, Width;
cout << "Enter the length and width of your rectangle " << endl;
cin >> Length >> Width;
	return 0;
}

And guess what, this code doesn't compile! Whaddya know. I get this error
--------------------Configuration: pointertofunction - Win32 Debug--------------------
Compiling...
pointertofunction.cpp
Linking...
pointertofunction.obj : error LNK2001: unresolved external symbol "double __cdecl Area(double,double)" (?Area@@YANNN@Z)
Debug/pointertofunction.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.


I dont' have MSDN so I have no clue what this error means. It seems as though this code SHOULD work, please tell me why it in fact doesn't.
thanks in advanced

NEVERMIND, I DID NOT INCLUDE THE FUNCTION DEFINITION, IT COMPILES NOW, HOW SILLY OF ME

I'VE FIXED EVERYTHING IT WORKS
