What are nested namespaces in C++?

Can you explain what nested namespaces are in C++?

Sure! Nested namespaces in C++ allow you to define a namespace within another namespace, helping to organize code.

Why would I want to use nested namespaces?

Using nested namespaces helps avoid name collisions and makes your code more modular and easier to manage.

Can you give me an example of nested namespaces?

Absolutely! Here's a simple example:

namespace Outer {
    namespace Inner {
        void func() {
            // function implementation
        }
    }
}

How do I access a function in a nested namespace?

You can access it using the scope resolution operator like this: Outer::Inner::func();.
