VS2008: Error LNK2019

-----------------------------------

Hey guys I've got some errors. My friend told me it's missing the body of my function. However, my body is obviously there when you look at this post:

pointofsales.h:

#define LIMIT 100
void posmath (int *quantity, double *price, char taxable);
void initPOS();

stdheader.h:

#include 
#include 
#include 
#include 
using namespace std;

pointofsales.cpp:

#include "stdheader.h"
#include "pointofsales.h"

void initPOS(){
	cout Linking...
1>pointofsales.obj : error LNK2019: unresolved external symbol "void __cdecl posmath(int *,double *,char)" (?posmath@@YAXPEAHPEAND@Z) referenced in function "void __cdecl initPOS(void)" (?initPOS@@YAXXZ)
1>D:\devel\c++\Workshop2\x64\Debug\Workshop2.exe : fatal error LNK1120: 1 unresolved externals
1>Build log was saved at "file://d:\devel\c++\Workshop2\Workshop2\x64\Debug\BuildLog.htm"
1>Workshop2 - 2 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========


This is a console application, I tried both compiling it to x86 and x86_64.

Please help?

Thanks,

RE:VS2008: Error LNK2019

-----------------------------------

This is the line from pointofsales.h:

void posmath (int *quantity, double *price, char taxable); 


This is the line from libpos.cpp:

void posmath (int *quantity, double *price, char *taxable){ 


There is a subtle but very important difference between these two lines.

Thanks, I solved it, there were also additional logic errors found.

However, once I got the compiler working I got another quirk.
