Example

Run on Compiler Explorer

main: () = {
    source:= std::vector<int>(10);
    std::iota(source.begin(), source.end(), 0);

    destination: std::vector<int> = ();

    std::ranges::copy(source.begin(), source.end(),
                      std::back_inserter(destination));
 
    std::cout << "destination contains: ";

    std::ranges::copy(destination, std::ostream_iterator<int>(std::cout, " "));
    std::cout << '\n';

    std::cout << "odd numbers in destination are: ";

    std::ranges::copy_if(destination, std::ostream_iterator<int>(std::cout, " "),
                         :(x: int) (x % 2) == 1);
    std::cout << '\n';
}

Output

destination contains: 0 1 2 3 4 5 6 7 8 9 
odd numbers in destination are: 1 3 5 7 9
