What is the primary purpose of using a namespace in C++?
Multiple Choice Options
- A✓ Correct Option
To encapsulate code and prevent identifier naming collisions
- B
To define the main entry point of a program
- C
To define the memory layout of an object
- D
To allocate variables strictly in global memory
Detailed Technical Solution & Explanation
Namespaces in C++ organize code into logical scopes and prevent name collisions between libraries or distinct modules that declare identical identifier names (e.g., classes, functions, or constants).
Option Analysis:
•
Option A (To encapsulate code and prevent ident...): Correct. Namespaces provide declarative regions that prevent global namespace pollution and name clashes.
•
Option B (To define the main entry point of a p...): The entry point is
main(), not a namespace.•
Option C (To define the memory layout of an object): Memory layout of an object is defined by its
class or struct.•
Option D (To allocate variables strictly in glo...): Namespaces provide scoping, not specific physical storage duration.
