I posted this question in 2016 and has some down votes.

Link to the topic: [how to use if then else](https://stackoverflow.com/questions/39093823/how-to-use-if-else-while)

I would like to receive some help to improve this question.

I would like to explain what the reason is for this posting:

When I started programming I had loads of questions. 4 years ago I didn't know much about programming. I was often obsessed with solving the problem and did not take enough time to read the guidelines well of this - by the way - terrific programming community. 

The result is that a few times I could not post at Stack Overflow. But for some reason, without me reacting on it, the ban was solved.

Some posts receive downvotes and comments about the reason for doing that. 

I also learned a few things. The main thing I learned: read and search thoroughly before asking. Many things are already there and duplicates are often not necessary. 

I hope users here can give a few good recommendations to post good questions. (Not a link to the user guidelines, but some good hints for example)

I would also like to know what criteria are used for not giving people a posting opportunity (temporarily).
