It is supports object-oriented programming language. It is developed by Bjarne Stroustrup. It is Developed at Bell Laboratory (U.S.A.). It was developed in 1979 basically it was developed to make writing good programs.</span></p><p><span style="font-family: arial; font-size: medium;">C++ programming language is a cross-platform that can be used to create high performance any C++ application.</span></p><p><span style="font-family: arial; font-size: medium;">C++ language is a gives programmer a high level control over system resources and memory management in our C++ program.&nbsp;</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4XfT3WcwQ4WljlZ9WTKXGTaEq0rCn2fBhgfWG_INQUKBERIVkGiKwLE6I_4vn3DH-lzvlxk43maNPWCvvyWfLvzpuN8iDJNyr2sF1AXwG8Uw-cWa8oW2-pSRsJtZO03RiyTK7uHWNBFWrkEApxUvS5LgHIAbxKdIA44Iy_gDzf2Jf_9vPfTZmvbL2VA/s1200/introduction-of-cplus-plus.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="C++ Introduction| History| Features| in Details" border="0" data-original-height="640" data-original-width="1200" height="342" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4XfT3WcwQ4WljlZ9WTKXGTaEq0rCn2fBhgfWG_INQUKBERIVkGiKwLE6I_4vn3DH-lzvlxk43maNPWCvvyWfLvzpuN8iDJNyr2sF1AXwG8Uw-cWa8oW2-pSRsJtZO03RiyTK7uHWNBFWrkEApxUvS5LgHIAbxKdIA44Iy_gDzf2Jf_9vPfTZmvbL2VA/w640-h342/introduction-of-cplus-plus.jpg" title="C++ Introduction| History| Features| in Details" width="640" /></a></div><span style="font-size: medium;"><div><span style="font-size: medium;"><br /></span></div><div><span style="font-size: medium;"><br /></span></div><div class="avsTOC"> <button onclick="avsToggle()"></button> <ol id="avsTOC"></ol> </div><br /></span><p></p><h2 style="text-align: left;"><span style="font-size: large;">A Brief History of C++</span></h2><p style="text-align: left;"><span style="font-family: arial; font-size: medium;">The Purpose of a programming language is too easy. C++ is not a new language, but one that is popularly programming language. As of this writing, the newest version of C++ is called C++22. It was ratified by the International Organization for Standardization(<b>ISO</b>) and published n December 2022.</span></p><h2 style="text-align: left;"><span style="font-size: large;">C++ Connection of C Language</span></h2><div><span style="font-family: arial; font-size: medium;">C++ programming language is developed by Bjarne Stroustrup at Bell Labs in 1979, C++</span></div><div><span style="font-family: arial; font-size: medium;">is successor to C language. C++ was designed to be an object-oriented programming language that implements concepts such as inheritance, Abstractions, Polymorphism and Encapsulation.</span></div><div><span style="font-family: arial; font-size: medium;">C++ features classes that are used to contain member data and member function. C++ is a popular compiler to have continued to support <a href="https://www.learncodingnivi.com/2022/11/introduction-c-language.html" target="_blank"><b>C Programming Language</b></a>.</span></div><div><span style="font-family: arial; font-size: medium;"><br /></span></div><div><span style="font-family: arial; font-size: medium;"><b>Note: </b>Knowledge of C programming Language is not a learning of C++ language. if your goal is to learn an object-oriented programming language like C++ then you can directly.</span></div><div><span style="font-family: arial; font-size: medium;">C++ you can do not need to learn a procedural languages like C Language.</span></div><div><h2><span style="font-size: large;">What are the main features of C++?</span></h2><div><ul><li><span style="font-family: arial; font-size: medium;">Simple</span></li><li><span style="font-family: arial; font-size: medium;">Powerful</span></li><li><span style="font-family: arial; font-size: medium;">Portable</span></li><li><span style="font-family: arial; font-size: medium;">Machine Independent</span></li><li><span style="font-family: arial; font-size: medium;">Structure Oriented&nbsp;</span></li><li><span style="font-family: arial; font-size: medium;">High Level Programming language</span></li><li><span style="font-family: arial; font-size: medium;">High Speed</span></li><li><span style="font-family: arial; font-size: medium;">High Efficiency</span></li><li><span style="font-family: arial; font-size: medium;">Flexible</span></li></ul><div><h2><b><span style="font-size: large;">What C++ is used for?</span></b></h2><p></p><ul><li><span style="font-family: arial; font-size: medium;">Game Development</span></li><li><span style="font-family: arial; font-size: medium;">Operating Systems</span></li><li><span style="font-family: arial; font-size: medium;">Compilers</span></li><li><span style="font-family: arial; font-size: medium;">Editors</span></li><li><span style="font-family: arial; font-size: medium;">Database Systems</span></li><li><span style="font-family: arial; font-size: medium;">Networks Drivers</span></li><li><span style="font-family: arial; font-size: medium;">Graphics Packages</span></li><li><span style="font-family: arial; font-size: medium;">Interpreters</span></li></ul><p></p></div></div></div><h2 style="text-align: left;">What is oops in C++?</h2><div><span style="font-family: arial; font-size: medium;">C++ Programming language is a support object-oriented programming language like&nbsp;</span></div><div><span style="font-family: arial; font-size: medium;"><b>Abstraction, Inheritance, Encapsulation and Polymorphism. </b>C++ support many features friend function, static function, and Exception and more features support in C++ programming language.</span></div><h2 style="text-align: left;"><span style="font-size: large;">What is new in C++ 2020</span></h2><div><span style="font-family: arial; font-size: medium;">C++ language is standard to have resulted in a language that is simple, easy to used for programming without compromising on the ability to write high performance applications.</span></div><div><span style="font-family: arial; font-size: medium;">C++ language that is still features that are expected in the next version in 2023.</span></div><div><span style="font-size: medium;"><br /></span></div><h2 style="text-align: left;"><span style="font-size: large;">Why Use C++ Programming Language</span></h2><div><span style="font-family: arial; font-size: medium;">C++ language is the one of the world's most popular programming language. C++ can be found in today's operating systems, C++ language use Graphical User Interfaces and Embedded system.</span></div><div><span style="font-family: arial; font-size: medium;">C++ is an object-oriented programming language.&nbsp; Which gives a clear structure to programs and allows code to be reused.</span></div><h2 style="text-align: left;"><span style="font-size: large;">Advantages of C++ Programming Language</span></h2><div><span style="font-family: arial; font-size: medium;">C++ language is an intermediate-level programming language. It is versatile and can be used for high-level programming language. C++ can also be used for low-level programming of libraries that work close to the hardware, such as device drivers.</span></div><div><span style="font-family: arial; font-size: medium;">C++ is the language of choice for artificial intelligence and machine learning compilers and interpreters of other programming languages.</span></div><h2 style="text-align: left;"><span style="font-size: large;"><span><br /></span><span>Difference between C Language and C++ Language</span></span></h2><div><span style="font-family: arial; font-size: medium;">C++ was developed as an extension of C and both languages have almost the same syntax.</span></div><div><span style="font-family: arial; font-size: medium;">The main difference between C Language and C++ Language is that C++ Support classes and objects.</span></div><div><span style="font-family: arial; font-size: medium;">But C language not support object-oriented programming language.</span></div><div><br /></div><h2 style="text-align: left;"><span style="font-size: large;">C++ Language Install IDE&nbsp;</span></h2><div><span style="font-family: arial;
