chaining

I have multiple functions the do different animations to different parts of the HTML. I would like to chain or queue these functions so they will run the animations sequentially and not at the same time. I am trying to automate multiple events in sequence to look like a user has been clicking on different buttons or links. I could probably do this using callback functions but then I would have to pull all of the animations from the different functions and regroup in the right pattern. Does the jquery "queue" help? I couldn't understand the documentation for the queue. Example, JQuery: function

I have a table with more than 9 rows. If I do this : $('table tr:gt(3):lt(6)') , shall I receive 3 or 6 elements at the end, and why? Are all selectors applied to the same primary selection, or are they successively applied on different selections? They're applied sequentially, so first you will filter away the first four elements ( :gt(3) ), then you will filter away all elements after the sixth ( :lt(6) ) element of the already filtered set. Imagine this HTML: <br/><br/> <br/><br/> <br/><br/> <br/><br/> <br/><br/> <br/><br/> Then do the following jQuery: $('br:gt(3):lt(6)').addClass('sel');

I have a function that takes an ostream reference as an argument, writes some data to the stream, and then returns a reference to that same stream, like so: #include <iostream> std::ostream& print( std::ostream& os ) { os << " How are you?" << std::endl; return os; } int main() { std::cout << "Hello, world!" << print( std::cout ) << std::endl; } The output of this code is: How are you? Hello, world!0x601288 However, if I separate the chaining expressions into two statements, like this int main() { std::cout << "Hello, world!"; std::cout << print( std::cout ) << std::endl; } then I at least get
