Névkörnyezetben

Névkörnyezetben, which translates to "in a namespace" in English, refers to the context in which a name is defined and interpreted. In computer programming, namespaces are used to organize code and prevent naming conflicts. They act as containers for identifiers such as variables, functions, classes, and types. When you refer to a name within a specific namespace, you are indicating that you are using the version of that name defined within that particular scope.

This concept is crucial for modularity and reusability. Without namespaces, it would be difficult to use libraries or modules that might define common names, as they could clash with names defined elsewhere in the project. By grouping related identifiers into a namespace, developers can create distinct scopes, ensuring that names are unique within their respective namespaces.

For example, if two different libraries both define a function called `print`, placing them in separate namespaces like `LibraryA::print` and `LibraryB::print` allows both to exist and be called independently without ambiguity. This organizational principle enhances code clarity, maintainability, and reduces the likelihood of errors arising from name collisions. The specific syntax for accessing names within a namespace varies between programming languages, but the underlying principle of providing a unique scope remains consistent.
