C++ Tutorial for Beginners
KNOW MORE ABOUT 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 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 camelcase 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 complete C++ series, where you will learn
everything you need to know - 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 which we specify using double quotes. If you
still want to learn more, use the link below this video to enroll in the full
course - the complete course contains three parts, each part being around three to
four hours long. Imagine you have a store and you have made $95,000 now as part of
your tax return. You have to pay state and county tax at different rates - so state
tax is four percent whereas county tax is two percent. Now I want you to write code
to show your total sales as well as your state tax, your county tax and the total
