Why can't applications see the source code?

Question

Programming

Only if the developer himself does not post it?

Answer 1

If you are talking about executable files, such as exe, then there is simply NO source code in them. Read what compilation is.
If you run the script yourself, then it is the source.
In general, you should at least read a little about how a computer and programs on it work.

Answer 2

It's time to learn what compilation is.

Answer 3

To hide the implementation, for example, and it was not stolen.
To protect the program from hacking.
To protect the program from plagiarism.
Also, because the source code itself is nothing, it is translated into instructions that are already running.

Answer 4

Because it's not there.

Answer 5

What, sorry, "applications"?

Answer 6

.net are decompiled to source. I decided to try to decompile my program using DotPicker , and I went nuts when I even saw my comments in the code.
