INTRODUCTION TO C++:
C++ is one of the most popular programming languages in the world and is used by large companies
and government agencies like Adobe, Google, Microsoft, Netflix, and NASA for building
performance-critical applications such as video games, device drivers, web browsers, servers, and
operating systems. While C++ may seem intimidating to some, you don't need to learn all of it in order
to write substantial programs. In this course, we'll explore major functionalities in the standard library,
a collection of pre-written code that provides the functionality that many applications require. We'll
also be using an Integrated Development Environment (IDE) which includes an editor for writing code.
To get started, select the free version of Clion and head over to jetbrains.com/clion/download to
download it - then you can activate your license or use one of the free alternatives.
C++ is a case-sensitive language, which means it is sensitive to uppercase and lowercase letters; so
make sure to type exactly as shown. The main function returns an integer, which is a whole number
like 0, 1, 2, 3, and so on; within the braces, we have written the code for this function. The value that
this function returns tells the operating system if our program terminated successfully or not. The
standard library has different files each serving a purpose; as you go through the course you will learn
more about the other files in the standard library. To create a console application, which is easier for
people learning a new language, remember patience is the first skill of a good programmer; if your
code does not get compiled pay close attention to this video. Once you understand the basics of C++
you will be ready to move on to writing applications with a graphical user interface if that is what you
want.
The ultimate C++ course is the first part of my complete C++ series. Each part is about three to four
hours long, so you can easily complete it in a day or two. By the end of this series, you will have a
solid understanding of C++ and you'll be ready to apply it in real life - for example, if you want to
build games with Unreal Engine, a popular gaming engine. To declare a variable in C++, first we have
to specify the type of data we want to store, then give our variable a proper meaningful name like 'file
size' and terminate this statement with a semicolon. Initializing variables is not mandatory but it's a
good practice to follow. As a small exercise for you, I want you to write code to swap the value of two
variables - this is a common interview question so let me explain what I mean: imagine instead of these
two variables we have two buckets; the first bucket filled with apples and the second bucket filled with
oranges. Now if we had these two buckets in real life, how can we swap their content? Think of a
solution!
We use constants when we don't want the value of a variable to change. Different teams have different
conventions for naming variables and constants, but popular conventions include the camel case and
pascal case. Modern editors make it easier to determine the type of a variable; hovering over a variable
will display its type. Increment and decrement operators can be used to modify variables, such as
printing 'x' which will result in 11, while printing 'y' will result in 10. As a reminder, adding comments
can help clarify code for future use.
This tutorial is the first hour of my C++ series, where you will learn everything you need - from the
basics to more advanced concepts. Using C++, we can write a sequence of characters on the standard
output, which is our console window. These double left angle brackets are called the stream insertion
operator - it's an operator for inserting something to our output stream. In this case, we're going to
write a string of characters that we specify using double quotes. If you still want to learn more, use the
