What is C++ programming

C++ has been around since 1979 and has become one of the world's most popular programming languages. It's used in many different industries, including education, finance, healthcare, engineering, and gaming. C++ is a general-purpose, object-oriented programming language that can be used to develop operating systems, games, graphical user interfaces, back end, and high-performance systems and applications.

C++ offers many advantages over other programming languages, such as Java and Python, because it allows you to write more efficient code with fewer lines of code than these languages would require. For example, if you wanted to write a program that prints out a message on the screen, then it would take several lines using Java or Python, whereas, in C++, all you need is one line: std::cout<< "Hello World";

What is C++

Another advantage of using C++ over other programming languages is that it is much faster, so if you are developing a game, then C++ would be better suited. Because games require fast responses from players who want them done quickly enough so they can keep playing without waiting for too long before their characters start doing something new

Attending a C++ tutorial is an excellent choice for programmers who want to have complete control over system resources and memory.

C++ tutorial gives you the ability to create your own data types, classes, and functions; this lets you define your own custom objects and structures. C++ is also a good choice if you want to customize your code for different situations.

Learning C++ is a great idea if you want to get into computer games, software engineering for high-end computing projects, cryptocurrency mining programs, and developing operating systems and other software for mobile devices.

C++ is a powerful programming language that can be used to write almost any program you can imagine and even some you can't imagine. It has many features that make it easy to understand and use. For example, it uses variables in a way that makes sense to most people: they've named values that hold data you want to store or manipulate. C++ also has functions, which are special subroutines that do specific things when called by other parts of your program.

The best thing about the C++ tutorial is that it doesn't require much math knowledge; you only need to know how to add, subtract, multiply and divide whole numbers. In fact, most programming languages are designed so anyone can learn them with no prior knowledge of computers or math whatsoever. They're built on simple concepts like variables and loops that anyone can understand once they're explained properly.

History of C++

C++ has been around for over 30 years. It was developed by Bjarne Stroustrup in 1979 at Bell Labs. C++ programming language is an extension of the C language with object-oriented features like classes and objects. Additionally, C++20 is scheduled to be released in the near future, and with it comes a host of new features that will make your code more secure and more efficient.

C++ is an object-oriented programming language used for creating applications on all kinds of platforms, including mobile devices, embedded systems, and the internet. C++ is one of the most popular languages in use today, but it's not without its problems, most notably security issues.

The International Organization for Standardization's C++ Joint Technical Committee upgraded C++ five times between 1998 and 2017. A new version, C++20, is scheduled to be released in the near future.

What is C++ used for?

C++ is a powerful, flexible programming language that can be used in almost every industry.

C++ has many real-world applications, including:

  • Video game development

  • GUI-based applications

  • Databases

  • Operating systems

  • Web browsers

  • Computation and graphics

  • Banking

  • The cloud

  • C++ is a general-purpose programming language, which means that it's used to create everything from games to web apps to operating systems. Its flexibility makes it ideal for many different types of projects, from small programs to large embedded systems.

  • Numerous well-known services, like MySQL, Microsoft Windows and Office, macOS, and others, were also developed using C++. The majority of large embedded systems use this language. When you need to have a huge buffer, a high level of parallelism, and minimal latency, C++ is a fantastic language to employ. Games and server applications both fall under this.

Steps to learning C++


The syntax for C++ is a programming language's grammar and the foundation for everything written in C++. This grammar also defines how C++ code is composed and understood.

C++ syntax is similar to other programming languages, but it has some unique features as well. The most important thing to know about C++ syntax is that it uses curly brackets to indicate the beginning and end of a block of code. For example:

{ } }

This indicates that all of the code within these curly brackets belongs together and should be executed together as one unit.

The next most important thing you need to know about C++ tutorial syntax is how it handles whitespace. Whitespace refers to any text that's not part of another character or symbol; in other words, any space or line break. In C++, whitespace can be used to separate different parts of your code from each other or from other things like comments or strings.

Practice basics:

After mastering syntax, a budding C++ programmer should get a grasp of the bigger aspects of the language.

First of all, it's important for a programmer to understand memory management and how it works in C++. This means knowing about pointers and references, as well as how to use them in your program. You'll also want to know about classes and objects, what they are and how to use them in your programs.

The crucial step after memorizing syntax is learning how to write functions. Functions define what happens when a certain event occurs, like clicking on an item in a drop-down menu or pressing enter on your keyboard. A function can be called from anywhere inside another function or even multiple times from within itself. This is called recursion. C++ programming language functions are very useful because they allow you to reuse code that's already been written instead of having to rewrite it each time it's needed again, which would take more time than simply calling it out into another function.

Functions and arrays:

Functions and arrays are two of the most important features of C++.

Functions are groups of statements that together perform a task. Every C++ program has at least one function, but it's possible and often advantageous to have more than one function in a program. For example, your program might contain a function to calculate the average score on an exam and a function to display an error message.

Arrays in a programming language are data structures that store a fixed-sized sequential collection of the same kind of elements. You can use arrays to store things like scores on an exam or the names of students in your class.


Strings are one-dimensional character arrays that finish with the null character "0."


Pointers are variables whose values are other variables' addresses. Pointers help perform C++ tasks more easily, and some tasks can't be performed without them.

In C++, pointers are used to create references to objects or data. The pointer itself doesn't contain any data; it simply holds the address of the location where the data is stored in memory. This allows you to write code that manipulates what's stored at the memory address pointed to by a pointer variable.


A reference is an alias, another name for a variable that already exists. If a reference is initialized with a variable, that variable's name and the reference name can be used interchangeably to refer to the variable.

References in C++ are useful when you need to keep track of one or more variables in your program. For example, if you have an array of numbers and want to add 1 to each number in the array, you could create a reference called sum that points to an integer variable. Then you could use this line of code:

sum = sum + 1;

Classes and objects:

Classes are a key feature to be learned in a C++ tutorial that is used to specify the form of an object by combining data representation and methods for manipulating that data into one package. A class provides the material used to create objects.

An object is a computer program's instance of a class. In other words, objects are instances of classes. An object can contain data and provide methods for manipulating that data. A method is an action performed by an object on its data. Methods are functions that can be invoked by other methods or by the program itself, using an object as if it were an argument passed by reference.


In C++, polymorphism is the ability to call a function to cause a different function to be executed, depending on the type of object invoking the function.

This is accomplished by using an overloaded operator or function. For example, if you want to concatenate two strings, you can use + or +=. If you want to do something else with those strings, like add an integer, then you'll need to overload those operators or functions.

Start practicing big:

With some programming skills learned from the C++ tutorial, it's time to put them to good use. One way to do this is by working on a project to see how various aspects of the language come together. There are many web-based resources for project ideas, such as simple programming games or building a banking app.

Another option is to work on your own personal project, something that excites you and that you can follow through with. You may not be able to build an app, but maybe you can write a program that prints out your favorite quote every day or turns your favorite song into lyrics that scroll across your screen? Whatever it is, make sure it's something you can complete in one sitting.

Upskill yourself:

C++ is a powerful programming language that can be used to build applications for any platform. It is widely used in areas such as game development and mobile app development, as well as web development.

With its ability to handle memory management, C++ is considered by many to be an ideal language for developing large-scale projects.

Intermediate and advanced C++ programming builds on the basics and provides programmers with a range of tools. Other core concepts underpinning the most powerful C++ functions are the object lifecycle and polymorphism.

C++ programming

How to be the best in C++?

When you're writing code, it's important to remember that the best programmers are not necessarily the ones who can write the most lines of code. The best programmers are the ones who can make their programs adaptable and easy to use across multiple platforms.

The way they do this is through generic programming, which allows them to write code once and reuse it across different projects. They can then compile their programs in ways that make them run faster or more efficiently, even if they don't have access to a specific platform at compile time.

If you want to be a programmer who gets it, you need to learn how to use generic programming language.

If you're not familiar with the concept of generic programming, it's a way of writing code that can adapt itself across various platforms and circumstances. For example, in C++, we have generics that are similar to templates in C++) which allow us to write more flexible code. This means that instead of having to write different functions for different types of data, such as strings or integers, we can write them once and then use them with different types of data later on.

This makes their programs more efficient because they have less code and fewer variables which means fewer bugs. It also makes them easier to maintain since there are fewer places where things could go wrong. Finally, it makes them more reusable since they can be used across platforms without any changes needed.

Frequently Asked Question

Should I learn C before I learn C++?

No, it is not necessary to learn C before you learn C++. C and C++ are both programming languages that can be used to create applications and programs for computers. While they are similar, there are significant differences between them. The main difference between C and C++ is that the latter is a superset of the former. This means that everything in C will also be true for C++, but not vice versa; therefore, if you know one language, it's easier to learn the other one. However, there are a few things that cannot be done using either language alone, so it's best to learn both at once. For example, neither language has its own graphics library or sound library; they require third-party libraries to provide these features
