What is C++ Programming? History, Features, Applications

    C++ is a high-level, statically typed, compiled, general-purpose, and open-source programming language. It is an extension of the C programming language which supports procedural, generic as well as object-oriented programming. C++ is often considered a low-level programming language because of its close relation to the system hardware and memory management.

    Does not matter whether it supports some concept of low-level programming still C++ is a high-level programming language. C++ was introduced in 1979 and it was developed by Bjarne Stroustrup at Bell Labs, New Jersey USA. The only purpose of developing C++ is to introduce the concept of Object-Oriented Programming in C. As C++ is an extension of C, so C++ contains all the properties of C, plus the concept of OOPs .

    Features of C++

    1. Statically Typed Programming

    C++ is a statically typed programming language which means, that when we declare a variable in C++ we also define its data type along with it. So the type checking in C++ occurred at compile time instead of run time.

    2. Object-Oriented Programming:

    C++ was introduced as the extension of C programming language with Object-Oriented Programming if we remove the concept of OOPs from C++ it becomes C. C programming was not able to solve real-world problems, because most of the problems required OOPs concepts, that is why Bjarne Stroustrup introduce C++ in which he introduced OOPs concepts such as:

    • Class
    • Object
    • Encapsulation
    • Inheritance
    • Polymorphism

    3. Standard Libraries(STL)

    A library is a collection of pre-written code that we can use in our program to increase the functionality of our program. Mostly all the libraries of C++ contain predefined functions that we can use so we do not have to write all the code from scratch. C++ also contains many standard libraries, and many of them are directly imported from the C programming language. All those libraries which are imported in C++ are not a part of any class, and as we know that C++ is an Object-Oriented programming language it also contains some extra libraries which are defined in a class. Some of the C++ library categories:

    • I/O
    • Strings
    • Math
    • Time, and date
    • Dynamic Allocation
    • Wide Character Function
    • STL Algorithms
    • STL Iterators
    • STL Allocators
    • Exception Handling Class

    4. C++ ANSI Standard

    ANSI stand for American National Standard Institute , this organization set standard for C++ use, it also makes sure that C++ becomes a cross-platform programming language, which means the code written in one system can be run on another without making any changes.

    Why learn C++?

    As in the previous tutorial we have discussed some of the reasons why you should choose C++ as your first programming language. No matter which programming language you choose, your main focus should be on the concepts which bind all the programming languages, with C++ you can clear all the concepts of programming in computer science. Once you are done with C++ basic concept, with some of the advanced topics, you can easily switch to any other programming language and after that, you would feel like all the programming languages are mere syntax but shear the same concepts.

    Use of C++

    • Yet many big-tech companies hire C++ developers to build desktop applications and software.
    • C++ is used to write code for device drivers because C++ is close to the hardware system.
    • Many famous browsers and software such as chrome, Firefox, etc. are built on C++, so they require a C++ developer for further development such as software.

    Conclusion

    This article is all about C++ overview, here we also have mentioned some of the major features of C++ so you get a brief idea about C++.
