Zeig mal deinen Code, wie du das ganze jetzt aufrufst
Hi flenders!
Ja der Code steht unten (leider etwas vermackt, weil ich da soviel dran rumgetestet habe). Naja, ich lege die Parameter ganz einfach fest, indem ich dem programm sage, ob der Parameter numerisch (long) oder ein string (char*) ist (also n oder s eingeben) und kann dann noch einen Wert eingeben. Naja probier's aus
