<header>Introduction</header>
<p>C# is a programming language developed by Microsoft.</p>
<p>C# is used in many fields , Some of them are:-</p>
<ol>
<li>Desktop App Development</li>
<li>Mobile App Development</li>
<li>Game Development</li>
<li>Backend Web Development</li>
</ol>
<p>C# is one of the most popular programming languages , Because:-</p>
<ul>
<li>It is a programming language developed by Microsoft</li>
<li>It is a high-level programming language which is easy to learn</li>
<li>It is more secure than many programming languages</li>
<li>It is close to C , C++ and Java ... It is easy for programmers to switch to C# or vice versa</li>
</ul>
</section>
<section class="main-section" id="Syntax">
<header>Syntax</header>
<p>Syntax is the structure of statements , Here is a simple program typed in C# to discuss the meaning of syntax</p>
<pre><code>using System;
namespace Hello
{
class MyProgram
{
static void Main(string[] args)
{
/* That is my first program
I created it today*/
// Printing text to console and filling the rest of that line
Console.WriteLine("Hello World!");
// Printing text to console without filling the rest of that line
Console.Write("Hello ");
Console.WriteLine("AAA");
}
}
}</code></pre>
</section>
<section class="main-section" id="Data_Types">
<header>Data Types</header>
<p>Some data types that are supported by C# :-</p>
<ol>
<li>integer (int) ... 1 , 500 , -200</li>
<li>double (double) ... 0.5 , 3.14 , -2.5</li>
<li>string (string) ... "AAA" , "What is your name ?"</li>
<li>character (char) ... 'A' , '+' , '5'</li>
<li>boolean (bool) ... true , false</li>
</ol>
</section>
<section class="main-section" id="Variables">
<header>Variables</header>
<p>Variables are containers for storing data values.</p>
<p>The syntax for declaring a variable and assigning a value to it is as following :</p>
<pre><code>data-type variable-name = value(data) ;</code></pre>
<p>For example :-</p>
<pre><code>int age = 20 ;
string FirstName = "AAA" ;
string full_name = "AAA BBB" ;
double _degree = 80.5 ;
char grade = 'A' ;
bool student = true ;
bool male = true ;</code></pre>
</section>
<section class="main-section" id="Type_Casting">
<header>Type Casting</header>
<p>Type casting means turning a certain data from a type to another one.</p>
<p>Syntax for type casting is :-</p>
<pre><code>(data-type) data</code></pre>
<p>For example :-</p>
<pre><code>double pi = 3.14 ;
int myInt = (int) pi ;
Console.WriteLine(pi) ; // 3.14
Console.WriteLine(myInt) ; // 3</code></pre>
</section>
<section class="main-section" id="User_Input">
<header>User Input</header>
<p>You already know that Console.WriteLine() is used to output text.</p>
<p>Now you are going to learn how to use Console.ReadLine() to get user input.</p>
<pre><code>Console.ReadLine();</code></pre>
<p>For example :-</p>
<pre><code>int age ;
Console.Write("Enter your age:") ;
age = Console.ReadLine() ;
Console.WriteLine("You are " + age + " years old") ;</code></pre>
</section>
<section class="main-section" id="Booleans">
<header>Booleans</header>
<p>Booleans are data types that can be used to control whether something is true or false(yes or no / on or off).</p>
<pre><code>bool male = true ;
bool student = true ;
bool permission_accepted = false ;</code></pre>
