How can I find out what language the program is written in?

Question

Programming

What software can be used to find out what language the program is written in? I got the software of the Soyuz ship and I want to decompile it, but for this I need to know what kind of language it is.

Answer 1

but nothing, that it could be secret software and they will stupidly shut you down?

Answer 2

What difference does it make what it was written on?
After compilation, there is always one result - a file with a set of instructions for a particular processor.
So your question should sound differently "which processor was in the union and where to get a decompiler on it"

Answer 3

In general, by opening the application with a notepad, you can immediately understand whether it is Windows or Linux. And most programs are written in C++.

Answer 4

They say that Google helps the persistent (and follow the links there for a walk). Accordingly, most likely pascal + asm.
