+```C#
+Console.WriteLine("Hello");
+```
+
+## Console.Write
+The same but doesn't add a line at the end of the sentece
+

+```
+
+## constants
+
+immutable values wich are known at compile time and 
+do not change for th life of the program
+
+just add the const keyword

+## Type casting
+
+Converting a value to a different data type
+Very useful because user input will always be strings
+
+```C#
+double a = 3.14;

+int c= 123;
+double d= Convert.ToDouble(c);
+
+int e= 321;
+String d= Convert.ToString(e);
+
+String g = "$";
+char h = Convert.ToChar(g);
+
+String i = "true";
+bool j = Convert.ToBoolean(i);
+```
+
+## GetType
+
+Get the type of a variable
+
+```C#
+double a = 3.14;
+Console.WriteLine(a.GetType())
+```

-# C# Malware Roadmap
+# C# Roadmap
+
+C# (pronounced “C‑sharp”) is a modern, 
+strongly typed, object‑oriented programming 
+language developed by Microsoft 
+that runs on the .NET platform and is 
+primarily used to build Windows applications, backend services, 
+and system‑level tools; 
+it combines high‑level productivity with access to low‑level operating 
+system features, making it suitable for everything 
+from desktop software and web APIs to automation, 
+game development, and cybersecurity tooling, 
+especially in Windows and Active Directory environments.
