Correct Answer (Detailed Explanation is Below)
B. false
Detailed Explanation
Answer: (B) false
std::is_pointer checks whether the supplied type is a pointer.
The type int is a normal integral type and is not a pointer type. Therefore, std::is_pointer<int>::value returns false.
If the type were int*, then std::is_pointer<int*>::value would return true.
This question tests the basic difference between an ordinary type and a pointer type using C++ type traits.
