Back when I graduated undergrad, 10 years ago I did some C++ for a CS minor. At work I've mostly done C with some small C++ projects.
I purchased Accelerated C++ and it's on the way. I'm thinking Effective Modern C++ is a good fit as well.
I'm currently reading learncpp and have read of the online stuff here as well.
The big thing is probably to start coding more and more as well.
Thanks for any input.
