This book uses std::cin, std::cout, std::vector, and std::string in many places. These should be old, familiar C++ features. By counting other features from the standard namespace in the code with this book, we can form a word cloud. The larger the word, the more often we use it. See if you recognize any, and look back when you have finished the book to remind yourself what you have learned.
