How do I make a script to a dll? And more.

[Amazonanimal]

Hi I'm new here and I don't know where I suppose to post this.

Anyway I need help, I'm new in c++ and I wanna know how I can make a script and make it to a dll.

I play a game named ROBLOX and if you play it do you know if they use c++ to make exploits and then they bypass it, it's what they do?

Thanks in advance - Amazonanimal
