Namespaces can be nested. So I can have one namespace within another.
System is most frequently used namespace
Inside System namespace is class called Console, which contains static methods.

The datatypes are defined as classes, they are equipped with methods. ToString() is a common method for all the datatypes.

We can use pointers in C# but we have to mark the functions that use pointers as 'unsafe'

unsafe static void Main()

To read numbers from console window use Parse method.

 Number = int.Parse(Console.ReadLine());
