Before you begin 350-001 your journey to understand how to write programs using C++, it is important to understand a few key concepts that you may encounter. These concepts, while not unique to C++, help in understanding programming in general. Readers who have experience in another programming language may wish to skim through or skip this section entirely.
There are many different kinds of programs in use today. From the operating system you use that makes 350-030 sure everything works as it should, to the video games and music applications you use for fun, programs can fulfill many different purposes. What all programs (also called software or applications) have in common is that they all are made up of a sequence of instructions written in some form of programming language. These instructions tell a computer what to do, and generally how to do it. Programs can contain anything from instructions to solve math problems or send emails, to how to behave when a video game character 640-802 is shot in a game. The computer will follow the instructions of a program one instruction at a time from start to finish.
