Is it possible to decompile a C++ executable file

I lost the source code to an executable file but still have the actual file. Is there any way to retrieve the original C++ code?

Duplicate of this question here.

Yes, it is possible, however when it comes to peeking function bodies and the like, you might have a little less luck. Operating systems like Kali Linux specialize in de-compilation and reverse engineering, so maybe look into a VM of that. And of course, windows has a lot of applications you can use as well to check the application code.

Look over the other question for specific app suggestions. :)

• Edit : You will most likely have lost all your logic and function bodies, but you might be able to recover the overall structure. It's your EXE so you might be more familiar with how it was all connected up.
