There are many reasons to learn C++. Whether it’s becoming an embedded systems engineer, game developer or just learning for the convenience, C++ is a great language. programming to learn.
C++ is one of the most popular programming languages ​​in the world. It is used for everything from building operating systems to making video games and making 3D movies. While it may have a steeper learning curve than others, C++ has incredible potential.
This guide will discuss the best way to learn C++ online. We will show you step by step how to learn C++ programming.
What is C++?
The C programming language was created by Bjarne Stroustrup. It was originally developed for the UNIX operating system and designed to simplify programming. The goal was to create a way to program something that would work on any machine. Today, C++ is used to write programs compatible with Linux, macOS, and Windows operating systems.
This language is known to have been created and tested by programmers throughout its history. This means that the language today has a number of features designed for specific use cases that programmers have encountered over the years.
C++ is a version of C which takes all the functionality of the latter. It supports object-oriented programming, which is a type of development that uses objects and classes. This structure helps reduce repetitions and increase the efficiency of the code.
Why should you learn C++?
C++ is known to be a more difficult language to learn than others like Java and Python. This is largely due to the fact that C++ has a more complex syntax. This can be difficult for those new to programming. That said, investing time in learning C++ can have many benefits for you and your career.
The first advantage of starting with a new programming language like C++ is the syntax. This syntax is similar to many other programming technologies, such as Go. This means that once you master C++, you should find it easier to start collecting more technologies, including the more modern ones.
That’s not all ! C++ is used in both software and hardware development. Knowing how to code in C++ gives you a better idea of ‚Äã‚Äãhow software and hardware work together. It’s a useful knowledge to have, no matter what path you take in technology.
C++ is also great to learn if you are interested in a career in technology. Considering the widespread use of C++, you shouldn’t have a problem finding a company that hires talented developers. As C++ is used for a wide range of applications, careers ranging from game development to software engineering are in your future.
What is C++ used for?
C++ is a generic language program, which means it has a range of uses. Today, C++ is used for game development, systems engineering, web browser development, embedded systems, etc.
C++ is widely used because it is "close to hardware". This gives the language a speed advantage. This is why game engines like Unity Engine and Unreal Engine rely on C++. The language is fast and can optimize system resources well for applications that require a lot of power.
You will find C++ in a wide variety of systems. Since C++ was designed as a system language, operating systems like Ubuntu and other versions of Linux rely at least to some extent on C++. Some in-vehicle systems such as smartwatches and home devices are known to rely on C++.
How long does it take to learn C++?
If you already have programming experience, you should expect to master C++ syntax in about two or three months. But, to really learn the language, expect to spend at least a year studying.
Professional C++ developers with years of careers often learn something new about the language. This is because, like all programming languages, there are so many ways to extend C++ that it is impossible to learn them all.
If you spend about ten hours a week learning C++, you will gain a good grasp of the fundamentals in a matter of months. Full-time students will learn the basics faster.
Is C++ hard to learn?
C++ is one of the most difficult languages ​​to learn. This is because C++ uses a number of paradigms. You will need to familiarize yourself with several programming concepts before you can use C++ effectively.
While you can say that learning a programming language is not easy, C++ has a reputation for being especially difficult for beginners. .
If you already have some programming experience, you should find it easier to learn C++ than without technical training.
How to Learn C++ Fast
Are you convinced that learning C++ is a good investment of your time? Great! The next step on your journey is to ask yourself: how can I learn C++ ?
The complex syntax used by C++ can make your trip intimidating, but don’t worry. Esploriamo alcuni suggerimenti per aiutarti a iniziare il tuo viaggio con il piede giusto.
Fase 1: prepara la tua tecnologia
Ci sono alcuni concetti diversi che devi conoscere familiarità con prima di iniziare a program. The first step in learning C++ programming is to prepare the technology and the integrated development environment. Here is a basic technology glossary that you should prepare before you start coding:
Text editor
A text editor is a tool where you can write programs via code Think of a text editor like a Microsoft Word document, but for programmers.
There are hundreds of text editors out there and which one you choose doesn’t necessarily matter. However, at the start of your trip, it is advisable to choose something simple. Here are some tips:
Compiler
You will also need a compiler on your computer. The compiler will read your source code. Then the compiler will convert your code into a format that the computer can read and execute. Here are some compilers you can use with C++:
- GCC (Windows, Mac, Linux)
- Visual Studio C++ Compiler (Windows)
- Clang (Windows)
Now that you have prepared With our tools, we can start talking about how to learn C++.
Step 2: Master the Basics
Once your technology is ready, you can begin your journey to learning C++. A mistake many new developers make is to start big and go back to more basic programming concepts. When starting out, you should start at the very beginning and aim to master the basics.
To get you started, let’s break down the main topics you’ll need to master in order to learn to program in C++.
C++ syntax and variables
The first step in learning a programming language is to understand the syntax of the language. Syntax refers to the rules and procedures that a language uses to interpret code.
So you should start to familiarize yourself with variables. Variables are a programming feature that allows you to store data and can be manipulated over time to reflect changes in your code.
Here are the main topics you should explore regarding C++ syntax and variables:
- How to create a C++ program
- How to receive program exit
- How to declare a variable
- How to concatenate variables
- How to use arithmetic operators
- How to accept input user in a variable
Flow control
Programmers use a series of instructions called conditional to control the flow of their programs. Conditions allow programmers to run certain codes only when a condition or set of conditions is met. Here is a list of flow control topics you should know:
Loops
Loops allow you to run a block of code multiple times and help reduce repetition in your coded. For example, instead of copying the same code five times in your code, you can create a loop that executes a single block of code five times.
Here are the main arguments you should know:
Functions
Functions are blocks of code that are executed when called in a program. So, writing a function allows you to write a block of code that is only executed when you want it, and that block of code can be executed as many times as you want in your program.
The main features of functions you should know about are:
- Built-in and user-defined functions
- How to declare a function < / li>
- The keyword of functions void li>
- How to return values ​​
- How to use parameters and arguments
Classes and objects
As mentioned above, C++ is an object oriented language. This means that it is based on classes and objects. Classes are projects that store the structure of part of a program, and objects use that structure to create a collection of data.
A class can store the structure of a car type. However, an object can store details about a single type of car, such as a 2020 BMW. The most important characteristics of classes and objects are as follows:
- How to create a class li>
- How to create an object
- Public and private declarations
- How to use constructors
- C++ inheritance
Vectors
Vectors are a type of list whose size can change. When programming, you can use vectors to store lists of data. These can help you better organize your code and keep it efficient. Here is a list of the main features of C++ vectors:
- Creating a C++ vector
- Indexing
- Adding and removing vector elements li>
- How to change values ​​in a vector
The best way to learn C++ online
We have discussed both the value of l learning C++ and the main topics that should learn. Now we have to ask ourselves: where can you learn these skills ?
The fact that C++ is so widely used is to your advantage. This means that there are plenty of resources you can count on to start learning programming. These resources all support different learning styles.
So if you prefer interactive tutorials, there is something for you. However, if you prefer books, the choice is vast.

Create a project
Construction projects are a great way to put theory you’ve learned into practice from books, free lessons, and tutorials. When you create a project, you have full control over what you design and how it works.
The first thing you need to create a project is an idea. You might be thinking about what to build, and this question is actually easier to answer than you think.
While you can build anything you want, a good way to come up with a design is to think about how to solve problems. In particular, think about the problems you encounter every day. So try to find a way to fix them using some code. Consider starting with a tutorial or searching online for a common problem people face if you get stuck.
The final idea you choose to work on should be the one that interests you. That way, if you run into an obstacle, you will be more motivated to move on and on.
Here are some basic project ideas for newbie C++ developers:
- Auto Insurance System
- Clothing Store Management System < / li>
- Noughts and crosses game
- Casino number guessing game
- C++ casino management system bank account
When building a project, remember to start small and then work your way up to explore more advanced ideas. For example, your first project could use your knowledge of classes. Later, you can embed inheritance, return 0, class models, standard libraries, function pointers, arrays, and other data types, and more into your code.
As you develop your skills through tutorials and online courses, you will create more complex programs and applications.
Join a Free Online C++ Community
Another common mistake new developers make is "coding in isolation". In other words, many people decide to learn programming on their own, without asking for help from others.
It makes sense that some developers would do this: learning to code is difficult. You may feel that you are charging others with basic questions. But this is not the case !
The best thing to do is to join a community of developers from the start and get involved as often as possible.
Benefits of joining a C++ community
Here are some of the benefits of joining a community :
- Meet people who have been in your shoes. In the Developer Forums, you’ll find programmers of all kinds, from beginners to experts. You will have no problem finding someone who has been in your shoes before. It can help you better understand where you are at and where you need to go to improve.
- It’s a safe place to ask for help. Developer communities are interested in programmers who help other programmers. If you have a question, instead of worrying about it yourself, you can ask someone in a community.
- You can practice your skills by helping others. Once you have mastered the basics of C++, you will be qualified to help people who are not as well versed as you on certain subjects, this will help you build your skills and become a better developer.
Best Communities for Beginner C++ Programmers
Now you might be wondering: Which communities can I join? Here is a quick list of the best C++ communities to help you get started. start:
- Dev. to : Dev.to is a discussion community for developers of all levels. Their C++ community is particularly active.
- GitHub : GitHub is code - sharing platform for developers and has a number of great projects you can contribute to.
- Stack Overflow : Stack Overflow is a community where they are developed urs can ask and answer these questions. If you have a C++ question - or want to help someone else - Stack Overflow is the place to go.
Train, then train more
The only way to hone your skills is to practice and practice again.
C++ has a steeper learning curve than other languages. Many people wonder if C++ is difficult to learn. You will probably end up asking yourself, " Should I stop ?" » Several times during your trip.
The answer to this question is always " No !" " If you keep and practice every day, you will become a better programmer.
Practice makes it easier for you to continue learning, because the more you practice, the more you will learn about common challenges associated with programming. You don’t need to train in a specific way, but here are some ideas to get you started:
- Work on projects: Take on projects as often as possible. This gives you a bigger goal to focus on and allows you to build on your existing skills.
- Join Edabit : Edabit is similar to Duolingo, but for developers. On Edabit you will find a number of challenges and exercises.
