vector<A>::iterator it = V.begin(); A *p = it; return 0; } 编译报错: error: cannot convert 'std::vector<A>::iterator {aka __gnu_cxx::__normal_iterator<A*, std::vector<A> >}' to 'A*' in initialization 错因: it是vector<A>::iterator型的,而指针p是struct A型的,两者不能直...

[gnu::always_inline]] attributes to those functions. Also change some internal helpers for std::move_iterator which can be unconditionally constexpr and marked nodiscard. libstdc++-v3/ChangeLog: * include/bits/stl_iterator.h (__normal_iterator): Make all members and overloaded operators const...
