code ascii

Question

bonjour à tous et merci d'avoir cliquez sur moi . Alors voila j'ai un probleme pour récuperer la valeur du code ascii dun caractere speciaux mais le resultat n'est pas celui que j'attends quelqu un peut mexpliquer pourquoi ? je voudrais qu'il maffiche le code ascii de Ö et il maffiche -99 .. je crois que c un probleme de charset siouplait alaide ! voici mon programe : MAIN.c

Jai simplifié le main c pour plus de lisibilité . ( non parckeu depuis que je me prends la tete avec ce probleme c devenu le foutoir ) main.c #include #include #include #include #include "charset.h" int main(int argc,char* argv[],int iNbArg,char ** capArg) { // Chaîne Iso8859-1 printf("declaration des variable "); PAUSE(); long i = 1; char password[]=("klbmfgh"); long j=0; long k=0; long pwdec[]={0}; char url[]=""; char verify[]=""; char *decode[17]={0}; char copycaeascii[100]={0}; char caSrc[]="ÖØÄÚÞÌ×îè×ÏÞÓÝèòØ";/* var unknown */ int iStrLen = strlen(caSrc),ret; FILE *unknown=NULL; printf("Transformation du contenu de la variable unknown en ASCII "); PAUSE(); char caEAscii[iStrLen]; ret = iso8859ToEascii(caSrc,iStrLen,caEAscii,iStrLen); caEAscii[ret] = 0; printf("Extended Ascii: %s ",caEAscii);/* EXTENDED ASCII */ strcpy(copycaeascii,caEAscii); printf("var unknown %s ",copycaeascii); /* var unknown copycaeascii */ PAUSE(); for (k=0;k < strlen(caSrc); k++) { printf("le code ascii de %c est %d ",copycaeascii[k],copycaeascii[k]); } system("pause"); return 0; }

J'ai déja essayé toute les forme de printf() %d %u %o %x etc .. rien ne marche je ne comprends pas .

tasken2 · Answer

ah ouai t'avais raison ca marche quand je declare la copy entend que char non signé.
merci bcp

tasken2 · Answer

oui mais ya vraiment un probleme avec le charse on dirait bien
je cherche donc le code ascii des caractere de la chaine ÖØÄÚÞÌ×îè×ÏÞÓÝèòØ
seulement je cherche a ckil me donne le code ascii du jeu de caractere en windows-1252.
donc pour Ö j'aimerais qu'il me renvois 214 et pas 153 comme il le fait maintenant.

j'ai changer ca dans main.c :
<hr size="2" width="100%" />

unsigned char copycaeascii[100]={0};

et

printf("le code ascii de %c est %u
",copycaeascii[k],copycaeascii[k]);

Siouplait ya personne pour m'aider ?

Alcantornet · Answer

printf("le code ascii de %c est %u
",copycaeascii[k],caSrc[k]); 

et si tu met ça donne quoi ?

tasken2 · Answer

Ca me donne 4294967254 je crois quec ladresse du pointeur chu pas sur.
mais ca va pour ca j'ai reussis a passer outre mon manque de compétence

 char caSrc[]="ÖØÄÚÞÌ×îè×ÏÞÓÝèòØ";
    long decode[17] = {214,216,196,218,222,204,215,238,232,215,207,222,211,221,232,242,216};

j'ai regarder sur google l'equivalent du code ÖØÄÚÞÌ×îè×ÏÞÓÝèòØ en windows-1252
et j'ai vu que ca faisait ca :
214,216,196,218,222,204,215,238,232,215,207,222,211,221,232,242,216
mais j'ai une variable qui va devoir contenir des caractere speciaux dont je n'ai pas prédéfini a l'avance leur code decimale  windows-1252.
et comme la console comprends rien a ce jeu de caractere j'ai  cru compris
qu'elle utiliser l'iso 8859 chu pas sur non plus bref ..
Quelque pense que je devrais creer une fonction pour simuler le jeu de caractere windows-1252  comme Julien Folly et sa library que j'utilise ?
comment devrais je procédé
