Please HELP with this New Hack?!!! Im new to c++ ???

DWORD WINAPI Hacks(LPVOID);

//{

#include <windows.h> //THe lib that we need

		if(GetAsyncKeyState(VK_F5) || GetAsyncKeyState(VK_F5) &1) { OneHitKill = true; Beep(550, 120); }
		if(GetAsyncKeyState(VK_F6) || GetAsyncKeyState(VK_F6) &1) {Change = true; Beep(550, 120); }
