What is cpp11?

How do you define a namespace?
A namespace is a declarative region that provides a scope to the identifiers (the names of types, functions, variables, etc) inside it. Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially when your code base includes multiple libraries.
What is type aliasing?
A type alias is a shorter name for a type. For example, you could create a User alias like this: type alias User = { name : String , age : Int } Rather than writing the whole record type all the time, we can just say User instead.

What is Typealias Kotlin?
In a project, we might declare variables of the same datatype multiple times like declaring a variable of Api response class type in Android or maybe using the same function again and again which might not make your code readable. Using type alias, in Kotlin we can make our code more readable for the developers.
