Hello there, and welcome to Section 2 of the complete C++ Developer Course. It's me, your instructor, John Baugh. I'll be taking you on a journey through the C++ programming language starting in this section with an introduction to the fundamentals. In this section, we'll be going through many interesting topics including; how to store different types of data in main memory, how to manipulate and perform operations on that data, including performing arithmetic on numbers, how to take our first steps towards helping our programs make decisions, how we can write our programs to communicate with the users including getting input from the user and showing them output and more. By the end of the section, I will assign you section projects to challenge you. The projects at the end of this section include a Mad Libs clone, and an average of three numbers program. Before we move on, I want to introduce you to a term I will be using quite often throughout this section and even the entire course, the word syntax. Syntax refers to the grammar rules of a language, and in our case the programming language, C++. Languages that people speak like English, German, Spanish, Hindi or Arabic, which are called natural languages to distinguish them from programming languages, are a little more forgiving most of the time where syntax is concerned. If I go into a restaurant where they speak Spanish, I might be able to order in Spanish but my grammar may not be perfect. The people will still probably understand me. Programming languages are not usually so forgiving. If you don't correctly use the grammar of a programming language, that is, you violate the language's syntax rules, then the compiler will refuse to convert the source code into machine code that the computer can understand. In short, we would say that your code doesn't compile. Hopefully, that terminology helps you as you move through the course. All that being said, let's get started with the next lecture and say hello to C++ programming.
