sliced example

Syntax	Code
Pipe	`rng \| boost::adaptors::sliced(n, m)`
Function	`boost::adaptors::slice(rng, n, m)`

Precondition: 0 <= n && n <= m && m < distance(rng)
Returns: make_range(rng, n, m)
Range Category: Random Access Range
Range Return Type: boost::sliced_range<decltype(rng)>
Returned Range Category: Random Access Range

sliced example

#include <boost/range/adaptor/sliced.hpp>
#include <boost/range/algorithm/copy.hpp>
#include <boost/assign.hpp>
#include <iterator>
#include <iostream>
#include <vector>

int main(int argc, const char* argv[])
{
    using namespace boost::adaptors;
    using namespace boost::assign;

    std::vector<int> input;
    input += 1,2,3,4,5,6,7,8,9;

    boost::copy(
        input | sliced(2, 5),
        std::ostream_iterator<int>(std::cout, ","));

    return 0;
}

This would produce the output:

3,4,5,
