Namespace

• A way of encapsulating items.
• Like a virtual folder or directory defined with namespace keyword at the top of a file followed by name of the namespace.
• Namespace can be used to organize code into logical groups and prevent name collisions.
• Allows to define two classes with the same name in different namespaces.
