Does being a good reader necessarily make you a good writer?

Good writer should be a good reader , but not necessary for a good reader to be a good writer 

Reading and writing are separate skills.  While they support each other, being good at one does not automatically imply you'll be good at the other.  In the same way as a person who is a good listener  cannot necessarily articulate their thoughts and ideas very well verbally.  Each skill requires active development.

Absolutely.  In fact, I always read before I start writing.  It establishes a mindset.  Reading the "voice" of another writer is how a writer finds his/her own voice. It helps organize the thought process.  And, specifically, it makes you think about presentation, form, sub-headings, structure.

Yes, for sure. Reading is the inspiration for writing. Reading and writing are two complementary skills.

Well, reading does help in performing a writer, however it doesn't necessary make a good writer, it takes much more than being a good reader in order to become a good writer 

Yes it does because the more you read, the more you are exposed to writing techniques; flow of content/ideas, vocabulary, grammar and other factors that different writers use. 

I must say that, the reading does help in performing a writer, however it doesn't necessary to make a good writer. 

sometimes writing comes with one as a natural skill, others improve this skill by learning, and a lot of readings. But for some even if they are good readers, they don't have the needed skills to be good writers. 

Yes. Reading widens your vocabulary and grammar as well as your imagination, which are all essential in writing. 

reading kar skta hon bas job ki bari zrorat he plz kahen mil jaye

No a good reader is not necessarily a good writer, to be a good writer, one must have the creativity and organization skills needed to become a writer.
