danke

complex data[N+1];
ifstream datei2("eimass_x.dat");
double time, value;
for(int line=0 ; line < N && datei2 >> time >> value; line++ ){
data[line]=value;
cout << time << " " << value << " " << data[line] << endl;
}

[...]eine idee?

Ja, die Fehlerbeschreibung posten und cpp-Tags benutzen.

hallo,
doch beim compilieren bekomme ich fehlermeldungen die ich nicht verstehe. eine idee?

Wie wäre es, wenn du die Fehlermeldungen mal posten würdest?

Ansonsten: Wie sieht die Deklaration von N aus?

int N

ich habe statt data[line]
data[line].norm() eingegeben und es hat funktioniert.

kann mir das bitte einer erklären?

danke

fehlerbeschreibung ist so lang, da ich es nicht kopieren kann

Willst du uns veräppeln (Ich finde den Witz nicht)

da ich es nicht kopieren kann, müsste ich es per hand schreiben.

lustig. jetzt brauchst du nur uns nur noch zu erklären, dass der kopierkonstruktor private ist.

danke

Jetzt kannste da rein klicken wo die Fehler stehen und rechte Maustaste dann auf kopieren zum einfügen hier rechte Maus Taste und dann auf einfügen klicken ^^

ODer halt Strg + C zum kopieren mit Strg + V einfügen.

Ich habe eben bei mir noch DEV C++ gefunden xD deswegen schreib ich einfach mal die Fehler Meldung^^

Das Programm

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{

complex data[N+1];  // Denk hier mal etwas drüber nach (:

// für ifstream musst du  <fstream> includieren  also #include <fstream>
ifstream datei2("eimass_x.dat"); 

double time, value; 

       for(int line=0 ; line < N && datei2 >> time >> value; line++ )
        { 
        data[line]=value; 
        }

     // time ausgeben was soll er den ausgeben von time ??
cout << time << " " << value << " " << data[line] << endl; 
}

// was soll das programm machen text aus einer datei auslesen ?

So kannst du Text aus einer Datei auslesen:

#include <iostream>
#include <fstream>

using namespace std;

int main(int argc, char *argv[])
{

int zeilen = 10;  // 10 zeilen aus der datei auslesen

ifstream datei2("eimass_x.dat"); 
string text_aus_datei[200];  // 200 zeilen können aus der datei ausgelesen     werden

         for (int i=0;i<zeilen;i++)
         {
             getline(datei2,text_aus_datei[i] );    

             cout<<text_aus_datei[i]<<endl;
         }
         datei2.close();

system("PAUSE");
}
