I want to build my career as a Softwar engineer,should i learn all the programming languages /some specific language clearly?

Question

If some specific languages, then whiche are that languages, mention plz...

Answer 1

The languages aren't pokemon. Figure out exactly what you want to do. (software engineer is too general, it really don't mean much) And learn what needs to be learned to do that thing.

Answer 2

The programming language you're using is just a tool. In order to be a software engineer you have to think like one, first.

Answer 3

you can learn basics of your first language in one week. Others will take 2 day. so in one month you will be familiar more than 10 languages. Then take an data structure course or read and complete a book. it will take approx. 2 3 weeks. Most of software developers are web developers. Since softwares are being made for money.

If you know javascript html css php mysql and a few javascript frameworks it will be enough.
