I am writing a code, in which one of the files uses set_intersection function, and the last parameter to this function is supposed to be an inserter. But when I compile the code, I see the following errors:
error C2039: 'inserter' : is not a member of 'std'
error C2873: 'inserter' : symbol cannot be used in a using-declaration
error C3861: 'inserter': identifier not found
Following is the code in the file which uses set_intersection function
#include "Query.h"
#include "TextQuery.h"
#include <set>
#include <algorithm>
#include <iostream>
using std::set;
using std::ostream;
using std::inserter;
using std::set_intersection;
// returns intersection of its operands' result sets
set<TextQuery::line_no>
AndQuery::eval(const TextQuery& file) const
{
// virtual calls through the Query handle to get result sets for the operands
set<line_no> left = lhs.eval(file),
right = rhs.eval(file);
set<line_no> ret_lines; // destination to hold results
// writes intersection of two ranges to a destination iterator
// destination iterator in this call adds elements to ret
set_intersection(left.begin(), left.end(),
right.begin(), right.end(),
inserter(ret_lines, ret_lines.begin()));
return ret_lines;
}
