They only teach C/C++ thorughout the courses and basic assembly for the
    MCU classes.  Is C++ really like the all out standard for business and
    electronic companies?

No, of course not.  And if it was, it wouldn't be in 10 years, anyway.
("business companies" probably still use COBOL.)  C++ is presumably good
enough at teaching the concepts of "modern software design" that you
shouldn't have TOO much trouble programming in whatever you need to.


    I mean i know vb inside and out, c++ i am very good at but by no
    means a pro, I cant do file access not off the top of my head!

With two high level languages and at least one assembler, you should be in
good shape, especially if you've ever written any "real programs" as opposed
to course assignments...  It'd probably be useful to understand the
differences between the "object oriented" languages currently in vogue and
the procedural languages of "the last generation."  Plain C or Pascal might
be a useful addition to your portfolio.

I've hired people who "didn't program" in the language we thought they'd
end up writing.  In the end, understanding the problem is more important
than understanding the language.
