What is C++ Programming?

C++ is an object-oriented programming language that gives programmers the power to create software that’s more robust, more flexible, and more secure. It also allows developers to write programs faster than with conventional programming languages. As a result, more programmers are finding ways to use C++ in their work.

If you’re new to C++, you might wonder what makes it so special. After all, there are other OOP languages out there. How come others don’t seem popular or widespread? You may be wondering the same thing if you’ve been exposed only to a few examples of what a language can offer. In this article, we look at what kind of programmer should learn C++ and why learning it is important for your future career as well as your love for software development in general. Keep reading for an overview of the most important features of C++ that every software developer should know.

What is C++?

C++ was created by Bjarne Stroustrup in 1985, who was inspired to design it after seeing the success of C. Bjarne worked at Bell Laboratories in New Jersey as a programmer before designing C++. He wanted to create a more flexible and efficient extension to C. C++ allows you to write object-oriented programs in a low-level fashion. It doesn't provide much abstraction, and it must be manually allocated and allocated memory. C++ is comparable to C; it is lightweight and compiled. You may create apps for a variety of platforms using C++, as well as other languages. C++ is a high-level, object-oriented, and imperative language descendent of C. It is still influencing C++ successors like C# and Java, as well as low-level languages like C.C++ is still a big influence on C-based languages like C# and Java.

Why Use C++?

C++ is an extremely powerful programming language that's used in a wide range of different industries. This includes everything from medicine to manufacturing to software development. Because of this, it's often used to create applications that need to be extremely reliable and efficient. This includes things like medical devices, industrial software, and even video games.

C++ offers a lot of benefits over other programming languages like JavaScript. For starters, it's much more reliable and stable than JavaScript. This means that your apps will be less likely to crash or otherwise malfunction as a result of bugs or flaws in the code itself. Furthermore, C++ is very flexible and forgiving. This makes it easier to write programs that can fit a wide variety of different needs and requirements. As a result, your apps are likely to end up being more versatile and useful overall.

Finally, C++ offers a lot of additional features that many other programming languages don't offer. This includes things like support for object-oriented programming, pointer arithmetic, and exception handling. Together, these features make C++ an extremely versatile tool that can be put to use in a wide variety of different contexts and situations.

Features of C++:

  • C++ is an object-oriented language (C is a procedural language). Code is more readable and maintainable thanks to OOP. OOP helps modularize and maintain programs efficiently by providing greater code clarity, code readability, troubleshooting, and making it simpler to add modifications without having to make major changes. Objects are used to execute real-time problems in five significant areas.

  • The data structure provides a protective cocoon for the data, concealing the irrelevant information from the end user. The user only sees the data necessary for the program's proper operation. It excludes any complicated, intrinsic information.

  • To achieve data abstraction, you must first encapsulate the data and its related methods and functions.

  • Encapsulation, while frequently synonymous with data protection, is rooted in a fundamental difference. Data protection focuses on the critical data aspects, whereas data encapsulation focuses on data. In contrast, protecting data from theft is the goal of secure coding.

  • A derived class (derived class) is a new class that is created when an existing parent class (base class) is copied (inherited) (or rederived). Code reusability is guaranteed by inheritance. This minimizes program redundancy and makes it easy to transfer duplicate or copy properties between classes.

  • C++ is well-suited to the needs of computer users. It has a syntax that closely resembles C, plus a comprehensive and structured design. Because C++ is frequently referred to as “C with classes”, its bottom-up structure allows you to decompose any project into its component pieces. Additionally, it includes a plethora of built-in library functions and a variety of data types.

  • It is a middle-level language that supports machine-level features as well as high-level language features. Because it is less cryptic and more closely associated with a human-readable and human-comprehensible language such as English, it is less alien and more readable to a human.

How does C++ differ from C Language?

C++ is a general-purpose programming language that was designed to provide programmers with high-level, efficient and robust tools for developing software. It is an extended version of the C programming language and supports object-oriented programming concepts. It has a wide range of applications in fields such as computer graphics, network communications, artificial intelligence and other areas. C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an extension to the C language so that it could be used for system software as well as application programs. Since then, it has become an industry standard for large-scale software development. C++ offers a wide range of features and capabilities not available in C, including support for object-oriented programming (OOP), generic programming and embedded systems programming. These features make it suitable for a wide range of applications, including desktop applications, web applications, mobile applications and even device drivers. C and C++ have a lot of differences. C++ is one of the most popular programming languages worldwide, with estimated usage in more than 90% of all modern software applications.

Basic Concepts of C++

In object-oriented programming, objects and classes are utilised to accomplish the task. Object-oriented programming is based on real-world concepts like inheritance, polymorphism, data hiding, and so on. When data and functionality are united into a single entity, this enhances the restrictiveness of the data's usage.

Class: An object-oriented programming language's fundamental building block is a data type called a class. It is the fundamental unit of structure that an object-oriented program is built from. Classes serve as the fundamental building block of object-oriented programing in C++. When a program invokes a function on an instance of a class, a new instance of that class is created.

Object: In object-oriented programming, an object is a unique instance of a class with characteristics and behaviours. Objects are the entities that are created to reserve memory space. There is no storage chunk defined in a class that will be allocated once objects are created.

Encapsulation: In object-oriented programming, encapsulation is the process of wrapping data and information into a single unit. A formal definition of encapsulation would be Binding the data and the method that can manipulate it together. In our everyday lives, we have departments for different courses, for example, computer science, and information technology. Each one of these has its own student population and curriculum. We can regard each of these departments as a class that protects the data about students and topics. A student is required to follow certain rules and guidelines in a course, for example, when to attend, and what methods to use. This encapsulation is real life because there is data and methods to manipulate it.

Polymorphism: Polymorphism refers to the ability of an object-oriented method to perform some work using multiple forms. This means that a polymorphic object-oriented method can perform some work using multiple forms. A real-life example would be a person who exhibits different behaviours depending on the situation. The ability of an object-oriented method to function in different ways is based on the situation or type in which it is used. Consider a mother, a manager, and a daughter, who exhibits different behaviours in various situations. This is how polymorphism was developed in C++. Operator overloadings and function overloadings are used to achieve polymorphism.

Inheritance: A class's inheritance capability is critical to object-oriented programmes because it allows for reusable procedures to be used, i.e. methods from other classes. Base classes and child classes are referred to as parent classes and subclasses, respectively, and the properties they inherit are known as parent properties.

Abstraction: When dealing with objects in an OOP application, the data abstraction process involves hiding the specifics of the data and displaying only the information the final user requires. A real-world example is helpful in understanding the concept. Whenever we ride a bike, we know to brake and increase the throttle, but we do not know how they function, and we do not wish to know either. This is why we hide the data in the same manner as data abstraction.

Advantages of C++

The ability to run the same program on various operating systems or interfaces without restriction is known as portability. C++ provides this capability.

The main advantage of C++ is its object-oriented programming capability, which includes objects, inheritance, polymorphism, data abstraction, and encapsulation. Moreover, it helps us address real-world issues by treating data as an object. This is because C lacked this feature.

C++ is a multi-paradigm language. A paradigm is a style of programming. It consists of the logic, structure, and procedure of the program. There are three paradigms in C++: generic, imperative, and object-oriented.

C++ is a multi-paraphrase language that encompasses logic, structure, and procedure. It includes as well as generic, imperative, and object-oriented paradigms. C++ is a procedural language closely related to machine language, which allows low-level data manipulation in C++ embedded systems and compilers. C++ embedded systems and compilers are created with the help of C++.

Disadvantages of C++

Pointers in C/C++ are rather tricky to understand and they occupy a lot of memory. If a wild pointer is used, the system might crash or behave improperly.

Even when object-oriented programming is safe for data, there are some security issues because of friend functions, global variables, and pointers, despite the fact that C is not object-oriented. You can use C++ to garbage collector the computer memory, but it does not have a garbage collector that automatically filters out unnecessary data.

The C++ thread feature is a relatively new concept that was not initially available. Now, C++ can support lambda functions, which are built-in threads.
