Up until this point in the book, you’ve been learning the basic principles of programming. First, you learned about the three basic building blocks of programming (sequential instructions, branches, and loops). Next, you learned about Boolean expressions, mathematical operators, variables, and constants. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
