need help about making Hacks by Programming language

Hello guys now I know

* Assembly
*C#
*JAVA
*Python

is there any way to make hack by these programming languages or Should I learn C++

There's .net injectors for C# but they should be detected by now. So you should learn C++ which is a native language that converts directly to asm instead of relying on .net framework. As such your DLLs won't have a self executed DllMain function since with .net DLLs you need to execute the exported functions. C++ is also well documented, whereas Delphi has only a few documentation is a lot harder in its syntax.

So you can choose either C++ or Delphi but be sure that it will be very hard in Delphi to do the same than in C++.

EDIT: I hadn't seen this but you can also make your own hack in assembly if you know how to make DLLs.

c++ is the best for the job..
c# or any other managed language can easily get detected and will be hard to make undetected again.. anti-cheats (doesn't have to be cf) can easily detect the c# net-framewok
System.Xml.Linq.dll
System.Data.dll
etc..
