Hi,
Thanks for solving my previous find() problem.
I found another problem of range_ex. The following code still works well with the old version of range_ex (Dec 2008), and cause a compile error with the newest version.
code:
#include
#include
#include
#include
#include
#include <iostream>
#include <vector>
bool is_even(int x) { return x % 2 == 0; }
int main()
{
using namespace boost::assign;
using namespace boost::adaptors;
using namespace boost::lambda;
std::vector<int> input;
input += 1,2,3,4,5,6,7,8,9;
boost::copy( input | filtered(bind(is_even, _1)),
std::ostream_iterator<int>(std::cout, ",") );
return 0;
}
compiler: msvc2008
