The former is deprecated with C++14. The standard says both are the same: The contents and meaning of the header<cstddef>are the same as the C standard library header<stddef.h>,except that it does not declare the type wchar_t, that it also declares the type byte and its associated operations (21.2.5), and as noted in 21.2.3 and 21.2.4.
