Question: 1 / 565

What is the result of declaring an object of a struct with no members in C++?

Compiler error

An object with size 0 bytes

An object with nonzero size

Declaring an object of a struct with no members in C++ will result in an object with nonzero size. This is because, even though the struct has no members, the compiler will still allocate memory for it to ensure proper alignment and to keep the struct distinct from other types. Therefore, the answer B is incorrect. Answer A is also incorrect because it is still possible to declare and use the struct, just with no members. Answer D is incorrect because declaring and using an object with no members of a struct does not result in undefined behavior.
