C# is a programming language developed by Microsoft.
-C# is used in many fields , Some of them are:-
--
-
- Desktop App Development -
- Mobile App Development -
- Game Development -
- Backend Web Development -
C# is one of the most popular programming languages , Because:-
--
-
- It is a programming language developed by Microsoft -
- It is a high-level programming language which is easy to learn -
- It is more secure than many programming languages -
- It is close to C , C++ and Java ... It is easy for programmers to switch to C# or vice versa -

Variables are containers for storing data values.
-The syntax for declaring a variable and assigning a value to it is as following :
-data-type variable-name = value(data) ;For example :-
-int age = 20 ;
-string FirstName = "AAA" ;
-string full_name = "AAA BBB" ;
-double _degree = 80.5 ;
-char grade = 'A' ;
-bool student = true ;
-bool male = true ;Variables are containers for storing data values.

+string full_name = "AAA BBB";

+bool male = true;
+
+
+ Type casting means turning a certain data from a type to another one.
-Syntax for type casting is :-
-(data-type) dataFor example :-
-double pi = 3.14 ;
-int myInt = (int) pi ;
-Console.WriteLine(pi) ; // 3.14
-Console.WriteLine(myInt) ; // 3+ Type casting means turning a certain data from a type to another one. +
+Syntax for type casting is :-
+
+ (data-type) data
+
+
+ For example :-
+
+ double pi = 3.14;
+int myInt = (int) pi;
+Console.WriteLine(pi); // 3.14
+Console.WriteLine(myInt); // 3
+
+
+ You already know that Console.WriteLine() is used to output text.
-Now you are going to learn how to use Console.ReadLine() to get user input.
-Console.ReadLine();For example :-
-int age ;
-Console.Write("Enter your age:") ;
-age = Console.ReadLine() ;
-Console.WriteLine("You are " + age + " years old") ;You already know that Console.WriteLine() is used to output text.

+
+ Console.ReadLine();

+ For example:-

+Console.Write("Enter your age:");
+age = Console.ReadLine();
+Console.WriteLine("You are " + age + " years old");

+
+ Booleans are data types that can be used to control whether something is true or false(yes or no / on or off).
-bool male = true ;
-bool student = true ;
-bool permission_accepted = false ;+ Booleans are data types that can be used to control whether something + is true or false(yes or no / on or off). +
