It cannot compare between C++ and Calculus because they are different subject. Learning C++ takes years to understand and to master the subject. One might think that learning C++ is boring. In my opinion, learning software engineering concepts and programming language, such as C++ is my passion. Definitely, mathematics helps you in a long run (in software engineering perspective) not in learning C++'s syntax.
Good luck with your studies.

I like to think about it in binary terms, yes or no, 1 or 0. Like, If x or y, then z, type of thing. So, in my opinion, math is very helpfiul, but more for the way you're taught to think in a procedural manner.
