The compiler has correctly realized that the return value is a constant70, so all it does is return that. Conclusion: Simplereflocal variables result in sub-optimal C++ but the C++ compiler can fix this and emit great machine code. LocalrefVariables From the Ternary Operator Next, let’s ad...
value_type see below difference_type value_type (only for atomic_ref<Integral> and atomic_ref<Floating> specializations)std::ptrdiff_t (only for std::atomic_ref<T*> specializations) For every std::atomic_ref<X> (whether or not specialized), std::atomic_ref<X>::value_type is X. ...
These functions are guaranteed to return only if value has changed, even if underlying implementation unblocks spuriously. Iforderis one ofstd::memory_order::releaseandstd::memory_order::acq_rel, the behavior is undefined. Parameters old-the value to check theatomic_ref's object no longer cont...
Here instead of initializing with default 0, we initialize with a user-defined value. The method will be similar to the method of a 1D vector.So for the outer vector,vector<T> arr(T,W) Where, W will be the user-defined element. Now here element is itself a 1D vector....

The value ofrequired_alignmentis the required alignment for an object to be referenced by an atomic reference, which is at leastalignof(T). Hardware could require that an object to be referenced by anatomic_ref<T>have stricter alignment than otherTobjects, and whether operations on anatomic_ref...
