Should a Bachelor of management studies graduate from India learn a?
Assuming that you will be applying these management studies to manage programmers at some point, I think an appreciation of the challenges they face is very important, whether or not you will want to write programs yourself. The only way to build that is to do some programming, it's not a waste of time at all. I think Java would do for this purpose and more, C++ gets more complicated than it has to for most application development.
