Waves, I forgot, is C+ an interactive language or one sided like HTML? I took a short online course in computer programming a couple of years ago and it was a hard course. It does keep the mind sharp though to try to learn something challenging. I'd say to try to do both, the C+ and the singing. If you can do C+ you are doing rather good mentally. The actual language C was one of the 1st programming languages wasn't it? I'd love to be able to get back into knowing all that stuff once my eye gets fixed. I did a whole website once using HTML code. The CSS was too hard but I did find a course or two that explained it easier than my earlier attempts. I just don't know where those courses are now. Maybe you could do web design from home for work? I think so.
