Syntax:
#include <algorithm> output_iterator set_symmetric_difference( input_iterator start1, input_iterator end1, input_iterator2 start2, input_iterator2 end2, output_iterator result ); output_iterator set_symmetric_difference( input_iterator start1, input_iterator end1, input_iterator2 start2, input_iterator2 end2, output_iterator result, StrictWeakOrdering cmp );
The set_symmetric_difference() algorithm computes the symmetric difference of the two sets defined by [start1,end1) and [start2,end2) and stores the difference starting at result.
Both of the sets, given as ranges, must be sorted in ascending order.
The return value of set_symmetric_difference() is an iterator to the end of the result range.
If the strict weak ordering comparison function object cmp is not specified, set_symmetric_difference() will use the < operator to compare elements.
