Hello ,

As your query is you want to complete your M.Tech from NITS with the branch Industrial Engineering and you want to know whether the knowledge of programming language C, C++ and Java is enough for that. I would like to tell you the course of Industrial Engineering, even in the phase of M.Tech doesn't require a much of programming knowledge, therefore if you even have C,C++ and Java in your hand you can go with which is somehow even enough but somehow how it will be better option to keep Python in your hand as well and that is even to learn the course so to be in the trend with the market.I guess you should opt for machine learning even and that will be anyway even better for you.

So it's better to have the knowledge of machine learning even in the view of keeping in trend with the technology market.

Further, if you have any query regarding the same you can let me know in the comment section below I can help you with that even. 

I hope your query is solved.

Thank you.
