◆ any_of() [2/2]

template<typename InputIterator , typename Predicate >
bool thrust::any_of ( InputIterator  first,
InputIterator  last,
Predicate  pred 
)

any_of determines whether any element in a range satifies a predicate. Specifically, any_of returns true if pred(*i) is true for any iterator i in the range [first, last) and false otherwise.

Parameters

lastThe end of the sequence.
predA predicate used to test range elements.
Returns
true, if any element satisfies the predicate; false, otherwise.
