The vector<bool> class is a partial specialization of vector for elements of type bool. It has an allocator for the underlying type that's used by the specialization, which provides space optimization by storing one bool value per bit.Syntax...

template<classInputIterator>vector(InputIterator first,InputIterator last,constallocator_type&alloc=allocator_type()); 这个构造函数使用范围[first, last)中的元素创建std::vector,InputIterator是输入迭代器类型,可以是指向数组的指针、其他容器的迭代器等。
