C++ routine to place all short into a set -

-

it should possible, since number of short ints less max_size() of std::set<short int>:

#include <iostream> #include <set> #include <limits.h> #include <math.h>  int main() {     std::set<short int> myset;     std::cout << "max size of myset " << myset.max_size() << std::endl;     std::cout << "number of short ints " << pow(2.0, double(sizeof(short int) * char_bit));      return 0; }

outputs

max size of myset 4294967295 number of short ints 65536

now, i'd place short ints set, meaning need routine iterate on short ints. if possible, general routine iterating on elements of given type. have insight?

just fun:

template <typename t> void fill_all_values( std::set<t> &s ) {     t t = t();     s.insert( t++ ); while ( t != t() ); }

one more fun solution:

template <typename t> void fill_all_values_2( std::set<t> &s ) {     typedef std::set<t>::size_type size_type;     size_type t_max = (size_type( 1 ) << (char_bit*sizeof(t))) - 1;     ( size_type = 0; < t_max; ++i )         s.insert( *reinterpret_cast<t*>(&i) );     s.insert( *reinterpret_cast<t*>(&t_max) ); }

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
