Namespaces

Namespaces in C++ provide a way to organize code into logical groups, preventing naming conflicts when using code from different libraries or parts of a large project. They act as containers for variables, functions, classes, and even other namespaces. You can access elements within a namespace using the scope resolution operator ::, nest namespaces for further organization, and selectively import elements or entire namespaces into the current scope using the using keyword to simplify code while being mindful of potential name collisions.
