Hello dear, I will suggest if  you are really interested in programming then go for IIIT-A, as it is the right place for you. It is the best items of coding culture. this is the first college to introduce a competitive programming course as a semester course. 

And being in ECE  branch you can easily take forward your career in the field of CS.

And if you are interested in core electrical then go for MNIT as is better in faculty and placement wise in core departments.
