How to compile bhop script

I found a bhop script on a forum but i don't know how to compile it, could anyone help?

//Basic Bhop By Habit
//Pretty sure its gonna be vac proof forever since it doesnt access any memory within the game
#include <iostream>
#include <Windows.h>
using namespace std;


int main(){
start:

CONST int scrolldown = -120;
CONST int scrollup = 120;
while (true){

if (GetAsyncKeyState(VK_SPACE))
{

while (true)
{
Sleep(20); //play around with this for other games// 20 is best for cs 1.6
mouse_event(MOUSEEVENTF_WHEEL, 0, 0, scrolldown, 0); //make sure you have mwheeldown binded to +jump in game




if (GetKeyState(VK_SPACE))
{
goto start;
}

}
}

}





return 0;
}

1. This is literally the worst bhop script I have ever seen
2. Please, if you don't know how to compile, you are MUCH MUCH better off downloading a simple bhop cheat off the internet, this will NOT BE ANY MORE UNDETECTED
3. With a 20ms sleep you will go very slow
4. Why not just stimulate a spacebar press, it will be frustrating when browsing the web with this exe open
5. Visual Studio 2015 Community -> c & p into a .cpp file and press "build" up the top

edit: press thanks if I helped!1!1111!!!!
