bit manipulation - Can I input/output bits in C++ -

-

i figuring out how compress files , wondering if bit manipulation output file.

current have string of variable size n contains 0's , 1's. ex: 010111001010110

i want output file contains n bits instead of n characters.

also, if possible, how can read bits , convert string?

thank you.

update: if cannot write out bits directly , have pack bytes, mean can convert 8 bits char , output list of char? if so, happens if try store "00000000", means null?

you can't write bits out directly, have pack them @ least in eights. yes, means writing out bytes. note output padded bytes , have it.

to convert string containing 0s , 1s raw data, easiest way either use std::bitset, if know length, or write loop advances eights, in

for (auto = 0; < str.size(); += 8)

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 $row): ?> <div id="<?=$...
