welcome to c++—a powerful computer programming language that’s appropriate for technically oriented people with little or no programming experience, and for experienced programmers to use in building substantial information systems. you’re already familiar with the powerful tasks computers perform. using this textbook, you’ll write instructions commanding computers to perform those kinds of tasks. software (i.e., the instructions you write) controls hardware (i.e., computers). you’ll learn object-oriented programming—today’s key programming methodology. you’ll create and work with many software objects in this text.
