thrust::equal
Defined in thrust/equal.h
-
template<typename InputIterator1, typename InputIterator2>
bool thrust::equal(InputIterator1 first1, InputIterator1 last1, InputIterator2 first2) equal
returnstrue
if the two ranges[first1, last1)
and[first2, first2 + (last1 - first1))
are identical when compared element-by-element, and otherwise returnsfalse
.This version of
equal
returnstrue
if and only if for every iteratori
in[first1, last1)
,*i == *(first2 + (i - first1))
.The following code snippet demonstrates how to use
equal
to test two ranges for equality.#include <thrust/equal.h> ... int A1[7] = {3, 1, 4, 1, 5, 9, 3}; int A2[7] = {3, 1, 4, 2, 8, 5, 7}; ... bool result = thrust::equal(A1, A1 + 7, A2); // result == false
- Parameters
first1 – The beginning of the first sequence.
last1 – The end of the first sequence.
first2 – The beginning of the second sequence.
- Template Parameters
InputIterator1 – is a model of Input Iterator, and
InputIterator1's
value_type
is a model of Equality Comparable, andInputIterator1's
value_type
can be compared for equality withInputIterator2's
value_type
.InputIterator2 – is a model of Input Iterator, and
InputIterator2's
value_type
is a model of Equality Comparable, andInputIterator2's
value_type
can be compared for equality withInputIterator1's
value_type
.
- Returns
true
, if the sequences are equal;false
, otherwise.
