2、加入main函数：



3、直接编译链接出错：



4、加入代码：#include <tchar.h>后编译成功

完成代码如下：

#include <Windows.h>
#include <tchar.h>

int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR    lpCmdLine,
int       nCmdShow)
{
UNREFERENCED_PARAMETER(hInstance);
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);
UNREFERENCED_PARAMETER(nCmdShow);

return 0;
}
