Ciao,
<BR>
<BR>Compilavo un semplice esercizio in C++ (semplicissimo ma e´ per un esame )
<BR>Il codice e´ il seguente (nome del file b.cpp):
<BR>
<BR>-------------
<BR>#include <iostream>
<BR>#include <cmath>
<BR>
<BR>using namespace std;
<BR>
<BR>int main()
<BR>int main()
<BR>{
<BR> int dim=0;
<BR> double **vettore;
<BR> cout << "Inserisci la dimensione del vettore";
<BR> cin >> dim;
<BR> cout << endl;
<BR> vettore=new double*[dim];
<BR>
<BR> for (int i=0; i<dim; i++)
<BR> {
<BR> cout <<"Inserisci il valore "<<i<<endl;
<BR> cin >> vettore;
<BR> cout << endl;
<BR> }
<BR>
<BR> for (int i=0; i<dim; i++)
<BR> {
<BR> cout "Valore "<<i<< " = "<<vettore<<endl;
<BR> }
<BR>
<BR> return 0;
<BR>}
<BR>
<BR>---------------
<BR>
<BR>Compilo con:
<BR>
<BR>g++ -o b b.cpp
<BR>
<BR>A quel punto l´output e´ il seguente:
<BR>--
<BR>
<BR>b.cpp: In function `int main()´:
<BR>b.cpp:18: error: no match for ´operator>>´ in ´std::cin >> *((+(((unsigned int)i) * 4u)) + vettore)´

<BR>------
<BR>
<BR>
<BR>Qualcuno riesce a capire dove sbaglio? Cerco solo di allocare dinamicamente un array!
<BR>Lo stesso codice l´ho compilato mesi fa su una fedora 2 (della quale purtroppo non ricordo la versione di gcc)....
<BR>
<BR>P.S. Dopo disperati tentativi ho concluso che non riesco ha visualizzare tutto il codice sul forum, alcune parti vengono inspiegabilmente cancellate, sorry<BR><BR>[ Questo Messaggio è stato Modificato da: wally il 19-02-2005 17:44 ]<br>

cortesemente riposta il codice disattivando l´html, bbcode, smilies... dimmi se già hai provato come ti ho detto a disattivare tutto
<BR>
<BR>ciao, rob<br>

<BR>Gia´ fatto <br>

mmm... così non riesco proprio a capire
<BR>se puoi, vieni in chat (sull´home page del sito c´è scritto server e channel), oppure mandami una mail col sorgente... il mio indirizzo gmail lo dovresti avere, dato che mi hai invitato te :-P
