template <typename _InputIt, typename _UnaryPredicate>
constexpr bool all_of(_InputIt first, _InputIt last, _UnaryPredicate p)

Checks if the unary predicate returns true for all elements in the range.

Parameters

• in first

  The iterator to the first element of the range.

• in last

  The iterator to the one-past-last element of the range.

• in p

  The user-provided unary predicate which will be called to test elements.
