I am new to Visual C++. I am trying to make a simple DLL for my practice. My coding is as follows:
CB.CPP

#include "stdafx.h"
#include "CB.h"



extern "C" EXPORT int WINAPI sum (int x, int y)//C2144 and C4430

{
    return x+y;
}

and CB.H

#define CBExport __declspec(dllexport)

#ifdef __cplusplus
extern "C"
{
#endif

extern "C" EXPORT int WINAPI sum (int x, int y);//C2144 and C4430

#ifdef __cplusplus
}
#endif

I am receiving the errors C4430 and C2144 while trying to build this prog. The C2144 error is as follows:
1>d:\context broker\cb\cb\cb\cb.h(14) : error C2144: syntax error : 'int' should be preceded by ';'
and C4330 error is follows:
1>d:\context broker\cb\cb\cb\cb.h(14) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
