Introduction : Les structures de données déjà vues ne sont pas suffisantes (les entiers, les réels, les chaînes de caractères…) en effet il ne permettent pas de stocker des données assez nombreux, une liste d’élèves par exemple. Donc on a besoin d’une autre structure de données. Ce sont les tableaux. On n’étudiera que les tableaux unidimensionnels ou vecteurs. 2. Notion de vecteur. On veut stocker les notes de 10 élèves pour un certain traitement. On a donc : Le tableau Notes qui contient 10 réels : <table style="width: 518px; height: 31px;" border="1" cellpadding="7" cellspacing="0"> <tbody><tr valign="top"> <td width="50"> 13 </td> <td width="51"> 10.5 </td> <td width="51"> 15 </td> <td width="51"> 18.25 </td> <td width="51"> 17 </td> <td width="51"> 9 </td> <td width="51"> 16 </td> <td width="51"> 15.25 </td> <td width="51"> 12 </td> <td width="51"> 16 </td> </tr> </tbody></table> Ce tableau est un vecteur, qui est remplie comme suit (Algorithme) : Notes[1]&lt;- 13 Notes[2]&lt;- 10.5 …. Notes[10]&lt;- 16. Commentaires : <ol><li>L’accès à une case du vecteur se fait par accès direct comme pour la chaîne de caractères. </li><li>Pascal ne contient aucune fonction ou procédure prédéfini qui agit sur les tableaux, sauf l’affectation est donc permise. </li><li>La case Notes[i] joue un rôle similaire à une variable réelle (dans ce cas) on peut donc appliquer une fonction comme Round(x) par exemple, cependant cette fonction n’a pas été appliquée sur le tableau mais sur un élément du tableau. </li></ol> 3. Déclaration d’un tableau : * Au niveau de l’algorithme : <table style="width: 553px; height: 97px;" border="1" cellpadding="7" cellspacing="0"> <tbody><tr valign="top"> <td width="308"> Objet </td> <td width="310"> Type/Nature </td> </tr> <tr valign="top"> <td width="308"> Nom_Tableau </td> <td width="310"> Tableau de Taille de Type_élément </td> </tr> </tbody></table> Exemple : <table style="width: 550px; height: 76px;" border="1" cellpadding="7" cellspacing="0"> <tbody><tr valign="top"> <td width="308"> Objet </td> <td width="310"> Type/Nature </td> </tr> <tr valign="top"> <td width="308"> Notes </td> <td width="310"> Tableau de 10 réels </td> </tr> </tbody></table> * Au niveau du Pascal : Var Nom_Tableau : array[BorneInf..BorneSup] of Type_élément.

ou ) ou ( dans ce cas corriger votre syntaxe en rajoutant le symbole manquant * Type mismatch : problème de type, ceci arrive quand vous utiliser la division avec les integer par exemple, dans ce cas utilisez plutôt div ou si vous utilisez mod pour les réels. Faites attention d'utiliser les bons opérateurs avec les bon types* Unknown identifier : ceci veut dire que vous n'avez pas défini votre variable, ça peut arriver aussi si vous écrivez mal une fonction ou une procédure2) Erreurs classiques :* N'oubliez jamais le uses wincrt; il est indispensable pour l'exécution * Si vous utilisez une boucle For, faites attention de bien mettre le to ou downto selon que votre boucle "monte" ou "descend" *Quand vous utilisez les integer, faites bien attention de pas dépasser la limite qui est de 32768m et donc ne pas manipuler des grands nombres. Utilisez le type longint si vous devez absolument travailler avec les grands nombres. 3) Autres erreursL'erreur 202 de RunTime peut parfois apparaître, cette erreur est dû au fait que vous utilisez une grande capacité de mémoire. Pensez dans ce cas de limiter l'utilisation, par exemple me déclarer pas un :array [1..100] of string;mais plutôtarray [1..100] of string[10]; Et puis bon courage à tout le monde de la part de notre blog.</content><link rel='replies' type='application/atom+xml' href='http://physiqueinfo.blogspot.com/feeds/8763074247665962510/comments/default' title='Publier les commentaires'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8337565636292676692&postID=8763074247665962510&isPopup=true' title='0 commentaires'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/8763074247665962510'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/8763074247665962510'/><link rel='alternate' type='text/html' href='http://physiqueinfo.blogspot.com/2011/05/conseils-pour-le-bac-pratique.html' title='Conseils pour le bac pratique - Programmation Pascal.'/><author><name>Anonymous</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/blank.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8337565636292676692.post-6882290566035057752</id><published>2011-05-01T12:48:00.000-07:00</published><updated>2011-05-01T14:43:11.753-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="exercice physique"/><title type='text'>exercice RC</title><content type='html'><div dir="ltr" style="text-align: left;" trbidi="on"><div class="separator" style="clear: both; text-align: left;">Exercice&nbsp;d’après&nbsp;<a href="http://www.chimix.com/">www.chimix.com</a></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0qo825yTBfm3zaJn6Qdw80hPRATPxjrEr0I2cxcAiFYaAaCraVi5lfd7rVTNLsFTwwKd0nymRh4Pc5JO1z4WjVFaiQNANrtOsQ1lACqg_bKS0p23eogxsC2spsf80kUdXU6BwI5Ytj0M/s1600/limoge11.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="164" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0qo825yTBfm3zaJn6Qdw80hPRATPxjrEr0I2cxcAiFYaAaCraVi5lfd7rVTNLsFTwwKd0nymRh4Pc5JO1z4WjVFaiQNANrtOsQ1lACqg_bKS0p23eogxsC2spsf80kUdXU6BwI5Ytj0M/s320/limoge11.gif" width="320" /></a></div>Un condensateur de capacité C, initialement chargé sous une tension U= 5 V est déchargé à travers un conducteur ohmique de résistance R= 10 kW.

Un acide est une espèce chimique capable de céder au moins un proton H+ 
Une base est une espèce chimique capable de capter au moins un proton H+ 
Un acide noté AH et sa base conjuguée notée A-&nbsp;forment un couple acide base noté: 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; AH/A- 
Ils sont reliés par une demie équation protonique: 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; AH=A-+H+ 
Exemple: acide éthanoique (aussi appellé acide acétique) 
CH3CO2H/CH3C02-&nbsp;(ion éthanoate, aussi appellé acétate) 
Certains éléments se comportent à la fois comme un acide et une base: on l'apelle amphotère. L'eau est amphotère. 
Elle joue le rôle de base dans le couple: 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; H3O+&nbsp;/ H2O 
Et le rôle d'acide dans le couple: 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; H2O / OH-<o:p></o:p></div><div class="MsoNormal" style="background: white; line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">2) Equation de réaction acido-basique<o:p></o:p></div><div class="MsoNormal" style="background: white; line-height: normal; margin-bottom: 12.0pt;">
Toute réaction acido basique est un transfert de proton(s) mettant en jeu deux couples. 
Si un acide A1H réagit avec une base A2- 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;A1H / A1- 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;A2H / A2- 
L'équation s'écrira: 
&nbsp;&nbsp; &nbsp; &nbsp;A1H + A2-&nbsp;= A1-&nbsp;+ A2H
 
Exemple: l'acide éthanoique réagit avec l'eau: 
&nbsp;&nbsp; CH3CO2H / CH3CO2- 
&nbsp;&nbsp; &nbsp;H3O+&nbsp;/ H2O 
 
L'équation est donc: 
&nbsp;&nbsp; &nbsp; CH3CO2H + H2O = H3O+&nbsp;+&nbsp;CH3CO2-<o:p></o:p></div></div></content><link rel='replies' type='application/atom+xml' href='http://physiqueinfo.blogspot.com/feeds/2325447975135461253/comments/default' title='Publier les commentaires'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8337565636292676692&postID=2325447975135461253&isPopup=true' title='0 commentaires'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/2325447975135461253'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/2325447975135461253'/><link rel='alternate' type='text/html' href='http://physiqueinfo.blogspot.com/2011/04/i-reaction-acido-basique-1-couple-acide.html' title='Réaction acido-basique'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8337565636292676692.post-6283863725660550624</id><published>2011-03-29T04:06:00.000-07:00</published><updated>2011-04-20T09:24:42.622-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="physique"/><title type='text'>cours TS physique / électricité chap6: équation de décharge d'un circuit RC</title><content type='html'><div dir="ltr" style="text-align: left;" trbidi="on"><iframe allowfullscreen="" frameborder="0" height="344" src="http://www.youtube.com/embed/sLimuql0dU4?fs=1" width="425"></iframe></div></content><link rel='replies' type='application/atom+xml' href='http://physiqueinfo.blogspot.com/feeds/6283863725660550624/comments/default' title='Publier les commentaires'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8337565636292676692&postID=6283863725660550624&isPopup=true' title='0 commentaires'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/6283863725660550624'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/6283863725660550624'/><link rel='alternate' type='text/html' href='http://physiqueinfo.blogspot.com/2011/03/cours-ts-physique-electricite-chap6.html' title='cours TS physique / électricité chap6: équation de décharge d'un circuit RC'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://img.youtube.com/vi/sLimuql0dU4/default.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8337565636292676692.post-7799475942099965492</id><published>2011-03-29T04:04:00.000-07:00</published><updated>2011-04-20T09:25:19.321-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="physique"/><title type='text'>Le dipole RL</title><content type='html'><div dir="ltr" style="text-align: left;" trbidi="on"><iframe allowfullscreen="" frameborder="0" height="344" src="http://www.youtube.com/embed/vGQ4xinm6mg?fs=1" width="425"></iframe></div></content><link rel='replies' type='application/atom+xml' href='http://physiqueinfo.blogspot.com/feeds/7799475942099965492/comments/default' title='Publier les commentaires'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8337565636292676692&postID=7799475942099965492&isPopup=true' title='0 commentaires'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/7799475942099965492'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8337565636292676692/posts/default/7799475942099965492'/><link rel='alternate' type='text/html' href='http://physiqueinfo.blogspot.com/2011/03/le-dipole-rl.html' title='Le dipole RL'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://img.youtube.com/vi/vGQ4xinm6mg/default.jpg" height="72" width="72"/><thr:total>0</thr:total></entry></feed>
