In this set of fresher-level C++ interview questions, one common topic is the concept of namespaces. Namespaces in C++ are used to organize multiple classes and functions, which simplifies application management..
The most commonly used namespace in C++ is the std namespace, which contains components of the standard library. Programmers can also create custom namespaces to encapsulate related functionality, helping to avoid name clashes in larger projects.
To access elements within a namespace, you can utilize the scope resolution operator (::) or the using directive.
