i want write program in c++ helps manage hockey pool, , 1 of key things need read off schedule week ahead. hoping use nhl website. there way have program download html file given url, , parse that? suppose once have file downloaded, simple file i/o do, im not sure how download file. i use library providing http abstraction. for example: cpp-netlib #include <boost/network/protocol/http/client.hpp> #include <string> #include <iostream> int main() { boost::network::http::client client; boost::network::http::client::request request("http://www.example.com"); request << boost::network::header("connection", "close"); boost::network::http::client::response response = client.get(request); std::cout << body(response); } i not think can easier that on gnu/linux compile with: g++ -i. -i$boost_root -l$boost_root/stage/lib -lboost_system -pthread my_main.cpp qhttp example quite long, since

hello i'm trying understand how 2-3 trees work, understood concept keys, store data itself, in leaves, or in nodes 1 key (internal node), , 2 keys (internal node) also, in advance i'm no expert on tree structure first sentence wikipedia page on 2-3 trees seems answer question data stored: a 2-3 tree in computer science type of data structure, tree every node children (internal node) has either 2 children , 1 data element (2-nodes) or 3 children , 2 data elements (3-nodes). seems me store data in each node of tree. wiki page has link java applet demonstrating inserts . edit: after reading comment, , having sample code, i'm inclined think data , key (as calling it) same thing (as chowlett has mentioned in answer). looking @ sample code (they storing ints) create twothreenode class holds pointers data storing, ensuring data class has overloaded comparison operators allow them sorted. follow algorithm before. i found interesting article,

i've been wondering quite time. there whole bunch of them , can overloaded, why not end , allow custom operators? think great addition. i've been told make language hard compile. makes me wonder, c++ cannot designed easy compilation anyway, undoable? of course, if use lr parser static table , grammar such e → t + e | t t → f * t | f f → id | '(' e ')' it wouldn't work. in prolog, parsed operator-precedence parser afaik, new operators can defined, language simpler. now, grammar rewritten accept identifiers in every place operator hard-coded grammar. what other solutions , parser schemes there , other things have influenced design decision? http://www2.research.att.com/~bs/bs_faq2.html#overload-operator the possibility has been considered several times, each time i/we decided problems outweighed benefits. it's not language-technical problem. when first considerd in 1983, knew how implemented. however, experience has been wh
