Ko tieši dara šīs rindas ? Daļēji saprotu, bet līdz galam nesaprotu )

Sveiki! Kādu funkciju (visprimitivāko) ir jāizmanto lai varētu centrēt tekstu konsolē ? C++ .

cout<<"                 ##########################";

Ar spaciem kaut kā nekatit

Arī labs http://learncodethehardway.org/ :]

Tur ir ruby, python, c, sql, regex pamācības un tajās ir viss sīki un kodolīgi paskaidrots.

Grāmatas nelietojam, atnākam iedo teoriju un viss, emm nu teoriju par to ko man vajag neiedeva.

Aleksej, paldies par video, noskatīšos

*Esejas ievadā parādi savu attieksmi pret ekonomistu uzskatiem par tirgus, valsts lomu un valsts funkcijām jauktas ekonomikas sistēmā; galvenos jēdzienus.

Man vajag uzrakstīt eseju, bet nevaru atrast nekur ekonomistu uzskatus :( par tirgus, valsts lomu un valsts funkcijām jauktās ekonomikas sistēmā.

Varbūt kāds var "vijibnutsa" ar google skill? Varbūt es slikti meklēju. Vismaz par tirgus lomu un valsts lomu jauktajā ekonomikā. (Latvijā)

Sveiki, es izveidoju šo kodu

<?php
$mysqlconnnect = mysql_connect ('localhost','root','85221802');
if (!$mysqlconnnect){
die ('Savienojums ar datubāzi netika veikts, ievadi pareizos datus!');
}
mysql_select_db ("cms", $mysqlconnnect);
$sql = "CREATE TABLE RegisteredUsers
(
Login varchar(15) NOT NULL,
Password varchar(15) NOT NULL,
Age int
)";
mysql_query ($sql,$mysqlconnnect);
mysql_select_db ("cms", $mysqlconnnect);
$sql2 ="INSERT INTO RegisteredUsers (Login, Password, Age)
VALUES
('$_POST[Login]','$_POST[Password]','$_POST[age]')";
if (!mysql_query($sql2,$mysqlconnnect))
{
die ('' . mysql_error());
}
else
echo '<b>Tika pievienota informācija datubāzē!</b>'
?>

Tad es mēģināju izdzēst tabulas kurās jau bija informāciju, kuru es ieguvu caur FORM (Login, parole, vecums un submit poga).Itkā izdzēsās tabulas ar informāciju, bet to vietā parādās vienmēr viens un tāds pats skaits rindu. Kad es FORMā ievadu tukšas ailes, pievienojas vēl tās rindas un izdzēst man viņas neizdodas.

Varbūt vajag kaut ko pie SQL koda pierakstīt lai neveidotos bezjēdzīgas tabulas ar tukšumiem?

Jā, tagad sapratu, veru ciet tēmu. Paldies.

Sveiki, man ir neliela problēma, sāku mācīties php+mysql un izveidoju šo kodu

<?php
$connect = mysql_connect('localhost','root','pw')or die ('<center><b>Lūdzu ievadi pareizus datus lai varētu pieslēgties datubāzei</b></center>');
if (mysql_query("CREATE DATABASE datubaze", $connect)){
echo 'Datubāze tika izveidota';
}
else{
echo '<b>Notika kļūda datubāzes izveidē: </b><br>' . mysql_error();
}
mysql_select_db ('datubaze', $connect);
$sql = "CREATE TABLE Registretieslietotaji
(
Login varchar(15)
Password varchar(15)
Age int
)";
if (!$sql){
echo '<b>Nevar izveidot jaunas tabulas</b>' . mysql_error();
}
else{
echo '<br><b>Tabulas tika veiksmīgi izveidotas</b>';
}
mysql_query($connect,$sql);
mysql_close($connect);
?>

Iegāju apskatīties google chrome un ieraudzīju šo brīdinājumu:

Warning: mysql_query() expects parameter 1 to be string, resource given in D:\AppServ\www\map\data.php on line 22

Kā var tikt vāļā no šī brīdnājuma?
