They hold classes and structures
What is a meaning of the namespace in vbnet?
Namespaces are the way to organize .NET Framework Class Library into a logical grouping according to their functionality, usability as well as category they should belong to, or we can say Namespaces are logical grouping of types for the purpose of identification.

What is the namespace in c?
C has no concept of namespaces. Namespaces are typically found in object-oriented programming languages as a means of organising code.
Can you have nested namespace?
Of course! All namespaces are nested by default since all namespaces exist in the global namespace. A class is also a namespace; therefore classes can also be nested.
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.
Is c plus plus a modular programming?
No, but it does support modular programming through namespaces.
What do you call one or more trees with disjointed namespaces?
One or more trees with disjointed namespaces are commonly referred to as "namespace trees" or "disjoint namespaces." In computing and data structures, this concept is often used to organize and manage data in a way that ensures that identifiers in one namespace do not conflict with those in another. Each tree can represent a different scope or context, allowing for clearer data management and organization.
Is namespace supported by oop?
No. A namespace is a language feature not an OOP feature. Java, for instance, doesn't use namespaces, it uses packages. Although similar in some ways, packages impose additional restrictions. E.g., packages have an impact on accessibility whereas namespaces and accessibility are orthogonal. Moreover, the directory structure must match the package structure (each file must be associated with one and only one package), whereas you can have multiple namespaces in the same file.
What is Namespace in Visual Basic NET?
In Visual Basic .NET, a namespace is a container that holds a set of related classes, structures, interfaces, enumerations, and delegates. It helps organize code and prevents naming conflicts by allowing the same name to be used in different contexts without collision. Namespaces can be nested and can be imported into other parts of the code using the Imports statement, making it easier to manage large codebases. This organization enhances code readability and maintainability.
What is difference between iostream and iostreamh in c plus plus?
<iostream.h> is an old style of programming and does not allow using namespaces. If you use <iostream> you can use namespaces, and limit number of predefined function (not used) included with your program.
