C#

There are lots of institute in Bangalore, which provides very good training in programming languages.

Dear, it may be difficult to get admission there but don't wait. It's my advice to you to take admission wherever you are getting the seats. Just apply for it and you can also wait for some time to check the cutoff list.
All the best dear.

The best beginner's language is C, then you can go for C+ and Java.
All the programming languages are interlinked.

It will not, but I suggest you that you can do the coding along with your studies, because if there is a gap in the studies, it is not so valued. Coding is not a big thing, as I am also doing B.Tech in computer Science and engineering. In every semester, we find almost a new programming language and along our regular studies we all practicing the coding too. I suggest you that due to only coding don't make a gap in your studies.

You can learn database administration and programming on websites as well as via video lectures. You should pursue B.Tech in computer science. In CSE, you will learn all about programming and database, data structures, etc.

Basic Programming was earlier teaching language for a beginner but it is no longer the first choice for any beginner. You are advised to start you first lessons on Programmming by learning C or C++ Programming language.
