What is nested class and what is its use in c plus plus?
A nested structure is simply one structure inside another. The inner structure is local to the enclosing structure. struct A { struct B {}; }; Here, we can instantiate an instance of A as normal. A a; But to instantiate B we must qualify the type because it is local to A: A::B b; If B were only required by A, then we can prevent users from instantiating instances of B simply by declaring it private: struct A { private: struct B {}; };
What is Namespace in NET framework?

What is nested logic?
In Nested Logic a Logic is contained within a Logic. If the Outer Logic is TRUE then the internal Logic is executed. Nested IF, Nested For, Nested While, e.t.c are some examples of Nested Logic in Modern Computer Languages.
When was Nested created?
Nested was created in 1977.

Can css comments be nested?
No, the CSS specifications explicitly state that CSS comments cannot be nested. If you try to do this, then your nested comments closing delimiter */ will close out the larger comment and anything after it will be rendered by the web browser. When comments are nested, the nested comment's beginning delimiter /* is ignored yet the closing */ is not.
Is a public function accessed like a non-member function?
A public function is scoped to the class in which it is declared. If declared non-static, then it must be invoked against an instance of the class but if declared static then namespace resolution is required to access the function. A non-member function is not scoped to any class but may be scoped to a namespace. If no namespace is specified, then it is scoped to the (unnamed) global namespace. If scoped to any other namespace then namespace resolution is required to access the function.
What are python namespaces?
In Python, a namespace is a system that organizes and manages the names (identifiers) used in a program. It serves as a container that keeps track of the mappings between names and the objects they refer to. Namespaces help prevent naming conflicts and provide a way to access and manage variables, functions, classes, modules, and other objects within a program. Here are a few key points about Python namespaces: Namespace Hierarchy: Namespaces are organized in a hierarchical structure known as the namespace hierarchy. At the top level, there is the built-in namespace that contains Python's built-in functions and types. Below it, there are global namespaces for each module or script, and within each module, there can be nested local namespaces for functions or classes. Scope: Each namespace has a specific scope, which defines the visibility and lifetime of the names within it. The scope determines where a particular name can be accessed or referenced in the code. Names can be either local to a specific function or class, or they can be global, visible throughout the module or script. Name Resolution: When a name is referenced in Python, the interpreter looks for that name within the available namespaces following a specific order called the "LEGB" rule. It checks the Local namespace first, then the Enclosing (nested) namespaces, followed by the Global namespace, and finally the Built-in namespace. This order determines which object a name refers to, and if the name is not found in any of the namespaces, a NameError is raised. Creating and Modifying Namespaces: Namespaces are created implicitly as you define variables, functions, classes, or import modules. You can also create namespaces explicitly using the `namespace` or `dict` objects. By organizing names into separate namespaces, Python provides a structured and manageable approach to name resolution and prevents naming conflicts, allowing for more organized and modular code. Understanding namespaces is essential for writing and maintaining Python programs effectively.
