  Where would be the best place to learn C++ >> I wouldn't consider any resume that has listed as his or her primary education reading books. I have done no courses at all, ever. I consider that sort of rejection a lucky escape, I regard any interview as going two ways, and anyone who regards how I learned to be more important than what I know, I'm glad not to work for them. I learned entirely by reading books. I got my first pro ...Show All
