Please, learn to google!
Don't ask questions in chats/forums like:
Why do we need inheritance?
Why is the sky blue?
What is polymorphism?
These kinds of questions you can should google first!
To google means:
- Open Google (or other search engine)
- Enter your request.
- I saw, but what's wrong with that I ask these questions in chats/forums?
- Believe me, 99% of your questions someone asked in forum a long time ago. This means that the answer is in the Internet. Therefore, asking a question to Google (or other search engine), you not only will get quick response, but also will not be disturbing other people.
- So, is asking questions in the chat/forums prohibited/unethical/bad?
Not really. If you have a question, first Google it, then if you can't find the answer, you can
search it in
Yandex
ask your question in forum.
