<h3 dir="ltr" role="presentation">Requirements before you start</h3>
<ul>
<li dir="ltr" aria-level="1">
To start using C++, you need two things:
</li>
</ul>
<ol>
<li style="list-style-type: none;">
<ul>
<li dir="ltr" aria-level="1">
A text editor, like Notepad, or an IDE, like VSCode to act as a platform for you to write C++ code
</li>
<li dir="ltr" aria-level="1">
A compiler, like GCC to translate the C++ code you have written which is a high-level language into a low-level language that the computer will understand.
</li>
</ul>
</li>
</ol>
&nbsp;
<h3 dir="ltr" role="presentation">What is an IDE?</h3>
<ul>
<li dir="ltr" aria-level="1">
IDE stands for Integrated Development Environment.&nbsp;
</li>
<li dir="ltr" aria-level="1">
It is nothing more than an enhanced version of a text editor that helps you write more efficient and nicer code.&nbsp;
</li>
<li dir="ltr" aria-level="1">
It helps to differentiate different parts of your codes with different colors and notifies you if you are missing some semicolon or bracket at some place by highlighting that area.
</li>
<li dir="ltr" aria-level="1">
&nbsp;A lot of IDEs are available, such as DEVC++ or Code Blocks, but we will prefer using VS Code for this tutorial series.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">Installing VSCode</h3>
<ul>
<li dir="ltr" aria-level="1">
Visit <a href="https://code.visualstudio.com/download" target="_blank" rel="noopener">https://code.visualstudio.com/download</a>
</li>
<li dir="ltr" aria-level="1">
Click on the download option as per your operating system.
</li>
<li dir="ltr" aria-level="1">
After the download is completed, open the setup and run it by saving VS Code in the default location without changing any settings.&nbsp;
</li>
<li dir="ltr" aria-level="1">
You will need to click the next button again and again until the installation process begins.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">What is a Compiler?</h3>
<ul>
<li dir="ltr" aria-level="1">
A compiler is used to run the program of a certain language which is generally high-level by converting the code into a language that is low-level that our computer could understand.
</li>
<li dir="ltr" aria-level="1">
There are a lot of compilers available, but we will proceed with teaching you to use MinGW for this course because it will fulfill all of our requirements, and also it is recommended by Microsoft itself.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">Setting up the compiler</h3>
<ul>
<li dir="ltr" aria-level="1">
Visit <a href="https://code.visualstudio.com/docs/languages/cpp" target="_blank" rel="noopener">https://code.visualstudio.com/docs/languages/cpp</a>
</li>
<li dir="ltr" aria-level="1">
Select C++ from the sidebar.
</li>
<li dir="ltr" aria-level="1">
Choose &ldquo;GCC via Mingw-w64 on Windows&rdquo; from the options shown there.
</li>
<li dir="ltr" aria-level="1">
Select the install sourceforge option.
</li>
<li dir="ltr" aria-level="1">
After the downloading gets completed, run the setup and choose all the default options as we did while installing VS Code.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">Setting Path for Compiler</h3>
<ul>
<li dir="ltr" aria-level="1">
Go to the C directory. Navigate into the Program Files. Then, open MinGW-64. Open MinGW-32. And then the bin folder. After reaching the bin, save the path or URL to the bin.
</li>
<li dir="ltr" aria-level="1">
Then go to the properties of &lsquo;This PC&rsquo;.
</li>
<li dir="ltr" aria-level="1">
Select &lsquo;Advance System Settings&rsquo;.
</li>
<li dir="ltr" aria-level="1">
Select the &lsquo;Environment Variable&rsquo; option.
</li>
<li dir="ltr" aria-level="1">
Add the copied path to the Environment Variable.
</li>
<li dir="ltr" aria-level="1">
And now,&nbsp; you can visit your IDE and run your C++ programs on it. The configuration part is done.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">Writing your first code in C++</h3>
Open VSCode. Here&rsquo;s the simplest print statement we can start with.
<pre class="language-cpp"><code>#include &lt;iostream&gt;
 
int main()
{
 std::cout &lt;&lt; "Hello World";
 return 0;
}
</code></pre>
Output:
<pre class="language-cpp"><code>Hello World</code></pre>
&nbsp;

Getting Started with C++

<h3 dir="ltr" role="presentation">What is C++?</h3>
<ul>
<li dir="ltr" aria-level="1">
C++ was developed by Bjarne Stroustrup, as an extension to the C language.
</li>
<li dir="ltr" aria-level="1">
Despite being an 80s creation, C++ has been a popular programming language throughout these years.
</li>
<li dir="ltr" aria-level="1">
C++ is a cross-platform language that can be used to create high-performance applications and software systems.
</li>
<li dir="ltr" aria-level="1">
C++ is very close to the hardware making it comparatively easy for programmers to give the instructions directly to the system without any intermediary giving programmers a high level of control over system resources and memory.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">Why should we learn C++/ Features of C++?</h3>
<ul>
<li dir="ltr" aria-level="1">
C++ is one of the world's most popular programming languages.
</li>
<li dir="ltr" aria-level="1">
In today's operating systems, GUIs, and embedded systems, C++ is widely used.
</li>
<li dir="ltr" aria-level="1">
It is one of the most popular programming languages for its object-orientedness. C++ is an object-oriented programming language that gives a clear structure to programs and allows code to be reused, lowering development costs.
</li>
<li dir="ltr" aria-level="1">
With C++, you can develop applications or heavy games that can run on different platforms.
</li>
<li dir="ltr" aria-level="1">
As C++ is close to other programming languages such as C# and Java, which makes it easy for programmers to switch to C++ or vice versa while it is actually very easy to learn.
</li>
</ul>
&nbsp;
<h3 dir="ltr" role="presentation">How is it different from C?</h3>
<ul>
<li dir="ltr" aria-level="1">
The syntax of C++ is almost identical to that of C, as C++ was developed as an extension of C.
</li>
<li dir="ltr" aria-level="1">
In contrast to C, C++ supports classes and objects, while C does not.
</li>
</ul>
