get mouse to move down

[Milhouse]

I'm trying to make a simple macro/program that moves your mouse down slightly whenever you press MOUSE1.
Sorry for clunky code, I'm very new to C++ and have no idea.

#include <windows.h>
#include <iostream>
#define VK_LBUTTON 0x01
using namespace std;


	SHORT WINAPI GetAsyncKeyState(
		_In_  int(VK_LBUTTON)
		);
