Detailed Description

template<class T = void>
class std::logical_and< T >

Function object for performing logical AND (logical conjunction). Effectively calls operator&& on type T.

Template Parameters

T	The type of the values.

Note

This class contains the member types result_type, first_argument type, and second_argument type. These aliases have been deprecated in C++17 and removed in C++20.
