Question

Quizplus · Accepted Answer

Individual namespace members can be accessed without a namespace qualifier only if they are mentioned in a using namespace::namespacemember declaration. Using the using namespace all; directive (option A) can lead to namespace collisions and is generally considered bad practice. Option B is incorrect as it suggests that all namespace members are automatically accessible without qualifiers, which is not the case. Option C is also incorrect as the namespace can be declared anywhere in the file, and is not limited to being inside of main.
