Getting into Visual Studio for External Hacking

I want to make a basic external application to read and write memory.



I installed Visual Studio 2019 and tried to run basic code similar to that shown in the above video ^
I have done basic cpp coding in classes, and I have a huge amount of python experience. I know how to code, but when I try to get into game reversing and cheat coding, I don't understand what SDK i need.

The code breaks down as soon as I try to compile

I assume I need to just grab some things through the Visual Studio installer. I installed VS 2017 after VS 2019 didn't work. Should I reinstall VS 2019, and then install something? Or just keep it as is.

Thank you guys so much for your help, if you decide to help a poor scrub like me out. I'm just getting into the CS hacking game now, and this is the first step towards creating some new content and cheats.

Again, thank you very much

Also, I know that <Windows.h> may not be the right syntax, maybe "windows.h" or something similar is actually correct, but the point is that the problem is certainly with the fact that my installation isnt complete.
