<h1>Learn to code</h1>
<p>Today i am going to tell about &nbsp;Computer language known as C++. &nbsp;it's history , uses , advantages ,disadvantages &nbsp;and a simple program in C++.</p>
<p><br></p>

<h1>History :</h1>
<p><br></p>
<p><img src="https://image.slidesharecdn.com/historyofcbyihsanwassan-160502190625/95/history-of-c-4-638.jpg?cb=1462216034" width="638" height="479"/></p>
<p>&nbsp;The C++ programming language has a history going back to 1979, when <a href="http://www2.research.att.com/~bs/">Bjarne Stroustrup</a> was doing work for his Ph.D. thesis. One of the languages Stroustrup had the opportunity to work with was a language called Simula, which as the name implies is a language primarily designed for simulations. <a href="http://staff.um.edu.mt/jskl1/talk.html">The Simula 67 language</a> - which was the variant that Stroustrup worked with - is regarded as the first language to support the object-oriented programming paradigm. Stroustrup found that this paradigm was very useful for software development, however the Simula language was far too slow for practical use.</p>
<p><br></p>
<p><br>
</p>
<p>Shortly thereafter, he began work on "C with Classes", which as the name implies was meant to be a superset of the C language. His goal was to add object-oriented programming into the C language, which was and still is a language well-respected for its portability without sacrificing speed or low-level functionality. His language included classes, basic inheritance, inlining , default function arguments, and strong type checking in addition to all the features of the C language .</p>
<p><br></p>
<p>&nbsp;The first C with Classes compiler was called Cfront, which was derived from a C compiler called CPre. It was a program designed to translate C with Classes code to ordinary C.&nbsp;</p>
<p><br></p>
<p><img src="http://www.cs.uah.edu/~rcoleman/Common/History/Images/CPPHistory01.jpg" width="750" height="157"/></p>
<p><br></p>
<p>&nbsp;In 1983, the name of the language was changed from C with Classes to C++. The ++ operator in the C language is an operator for incrementing a variable, which gives some insight into how Stroustrup regarded the language. Many new features were added around this time, the most notable of which are virtual functions overloading<a href="http://www.cplusplus.com/doc/tutorial/functions2/#function_overload"> </a>, references with the &amp; symbol, the const keyword, and single-line comments using two forward slashes .</p>
<p>&nbsp;In 1985, the first edition of the C++ programming language was released, which became the definitive reference for the language, as there was not yet an official standard.The first commercial implementation of C++ was released in October of the same year.</p>
<p>&nbsp;C++ is standardized by an ISO working group known as JTC1 /SC22 / WG21. So far, it has published four revisions of the C++ standard and is currently working on the next revision,C++2107.In 1998, the ISO working group standardized C++ for the first time as <em>ISO/IEC 14882:1998</em>, which is informally known as <em>C++98</em>. In 2003, it published a new version of the C++ standard called <em>ISO/IEC 14882:2003</em>, which fixed problems identified in C++98.The next major revision of the standard was informally referred to as "C++0x", but it was not released until 2011. C++11 included many additions to both the core language and the standard library .</p>
<p><br></p>
<h1>&nbsp;Advantages :</h1>
<p><br></p>
<ul>
  <li>Object oriented</li>
  <li>Portable language (writing a program irrespective of operating system as well as Hardware)</li>
  <li>Low-level language like Assembly language on Machine language called portable.</li>
  <li>C++ use multi-paradigm programming. The Paradigm means the style of programming .paradigm concerned about logics, structure, and procedure of the program. <a href="https://tekslate.com/class-in-c-with-examples/">C++</a> is multi-paradigm means it follows three paradigm Generic, Imperative, Object Oriented.</li>
  <li>It is useful for the low-level programming language and very efficient for general purpose.</li>
  <li>C++ provide performance and memory efficiency.</li>
  <li>It provides a high-level abstraction.</li>
  <li>In the language of the problem domain.</li>
  <li>C++ is compatible with&nbsp;C.</li>
  <li>C++ used reusability of code.</li>
  <li>C++ used inheritance, polymorphasm.</li>
</ul>
<p>With the use of C++ in development of modern games, operating systems, browsers, and much more, it is safe to say that C++ is irreplaceable.<br>
</p>
<blockquote>Many major applications like</blockquote>
<ul>
  <li><code>Adobe Products like Photoshop, Illustrator, InDesign</code></li>
  <li><code>Amazon - one of the biggest e-commerce sites</code></li>
  <li><code>Autodesk products for Computer Aided Design</code></li>
  <li><code>Facebook - social networking site are heavy C++ centric product</code></li>
</ul>
<blockquote>Moreover, the fact that there’s a huge community improving C++ on every iteration means that it is only expected to be used even more in the coming future.&nbsp;</blockquote>
<blockquote>&nbsp;</blockquote>

<p><br></p>
<blockquote>&nbsp;<strong>C++ job opportunities and salary</strong><br>
<br>
C++ developers can expect an average salary yearly 100,000<a href="https://gooroo.io/analytics/skill/Cpp/#.V8-qYfl96Uk"> </a>&nbsp;salary with over 7,700 jobs advertised every month.<br>
<br>
The requirement of jobs comes mostly from game development, rendering engines and the windows applications.</blockquote>
<h1>Disadvantages :</h1>
<p><br></p>
<ul>
  <li>It has less security</li>
  <li>C++ has a bootable</li>
  <li>Complex in a very large high-level program.</li>
  <li>Used for platform specific application commonly.</li>
  <li>For a particular operating system or platform, the library set has usually chosen that locks.</li>
  <li>When C++ used for web applications complex and difficult to debug.</li>
  <li>C++ can’t support garbage collection.</li>
  <li>C++ is not secure because it has a pointer, friend function, and global variable.</li>
  <li>No support for threads built in.</li>
</ul>

<blockquote>&nbsp;This program takes a positive integer from user and stores it in variable n.Then, <code>for</code> loop is executed which checks whether the number entered by user is perfectly divisible by i or not.The foor loop initiates with an initial value of i equals to 2 and increasing the value of i in each iteration.If the number entered by user is perfectly divisible by i then, <em>isPrime</em>&nbsp;is set to false and the number will not be a prime number.But, if the number is not perfectly divisible by i until test condition <code>i &lt;= n/2</code> is true means, it is only divisible by 1 and that number itself.So, the given number is a prime number.&nbsp;</blockquote>

Nice post! It shows a good review of classic C++. It does not sound like English is your first language, so I admire you for learning and practicing. Keep it up!

Maybe you will do C# next? Java would probably be the next logical, historically accurate language to review. C# is the best of both world's and my favorite!
