Yahoo: The 4 Mutable Signs in Astrology, Explained: Gemini, Virgo, Sagittarius, Pisces
Gemini, Virgo, Sagittarius, and Pisces make up the mutable signs in astrology. But what does "mutable" mean? According to expert astrologers, mutable signs are adaptable and dynamic. Their ...
Usage mutable type specifier lambda-declarator that removes const qualification from parameters captured by copy (since C++11)
an object whose type is const-qualified, or a non- mutable subobject of a const object. Such object cannot be modified: attempt to do so directly is a compile-time error, and attempt to do so indirectly (e.g., by modifying the const object through a reference or pointer to non-const type) results in undefined behavior.
If an iterator falls into one of these categories and also satisfies the requirements of LegacyOutputIterator, then it is called a mutable iterator and supports both input and output. Non-mutable iterators are called constant iterators.
If UnaryFunc is not CopyConstructible, the behavior is undefined. If the iterator type (InputIt / ForwardIt) is mutable, f may modify the elements of the range through the dereferenced iterator. Unlike the rest of the parallel algorithms, for_each is not allowed to make copies of the elements in the sequence even if they are TriviallyCopyable.
Their effects may be surprising if the member function does not have a reasonable implementation. std::cbegin is introduced for unification of member and non-member range accesses. See also LWG issue 2128. If C is a shallow-const view, std::cbegin may return a mutable iterator. Such behavior is unexpected for some users. See also P2276 and P2278.
Returns an iterator or a sentinel that compares equal to the past-the-end iterator of the join_with_view. 1) Returns a mutable iterator/sentinel or const iterator/sentinel.
