WebJan 19, 2024 · The vector 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 C++ template > class vector Remarks Actually since std::vector default-initializes all its values, and false is the default value of bool, for that specific case you can even simplify it to std::vector m_allFalse (5); If you want more general values, you'll have to copy them in, for example:
