| Paul <pepstein5@gmail.com>: Sep 14 12:45PM -0700 Could someone possibly explain to me the relationship between fixed width integer types and the std namespace? On my compiler, if I #include <cstdint> then std::int8_t yy = 65; works fine but also int8_t z = 65; also works. (And yes, it gives 'A'). Does int8_t belong to the std namespace or not? How can this designation be optional? Thanks for your help. Paul |

It Came From Outer Space. Or, well, C99. > How can this designation be optional? <cstdint> guarantees to provide it in namespace `std`, and may also provide it in the global namespace. <stdint.h> guarantees to provide in the global namespace, and may also provide it in the `std` namespace. A header wrapper such as ¹<stdlib/c/stdint.hpp> that includes both headers, guarantees that the name is in both the global namespace and the `std` namespace. Guaranteed behavior is IMHO preferable. But if you don't want to use such a wrapper, then including <stdint.h> is the more practical choice: <cstdint> just adds complication, for historical idealistic (or what I believe to be idealistic) reasons, and effectively reduces portability, since non-qualified use of the name may compile with the compiler used for original development, and not with others.

That is my own opinion at least, and so this talk starts with a perspective question: What "is C++," really? The language continues to evolve and change; as it does so, how can we be sure we're picking C++ evolutionary improvements that not only don't lose its "C++-ic" qualities, but make it a better C++ than ever?"
