Can I get my hands on close source( != open source)to study.

Question

When I download a app I download it's source code too. (right?)
can I access that code?
if no, why ?
and also how do they(the creator of app) made that sure?

Answer 1

What you want to do, I think, is very similar to this:

Although I personally do not think it's worth it, you may find a lot of code that is not applicable to anything or anything that you have not seen in an open source project.

Answer 2

no when you download an app you don't download its source, you just download the executable.

Answer 3

thanks all you guys..🖒
I think I understand now

Answer 4

When you download a pre-compiled binary (example: .exe; .bin) it _does not_ come with the source (usually). Depending on the licence, reverse engineering is usually _illegal_ even for personal use (an ongoing political battle).

Legality aside, reverse engineering is hellishly time consuming and requires knowledge beyond what you clearly have. You'll have a better chance forking a FOSS alternative and adding or removing what you want.
