Bekam ich [Fehler] Zuordnung zu Ausdruck mit Arraytyp sobald ich kompilieren Sie diese. Die Fehler-Zeile ist diff=abs(experiment[2]-100)*100 /100;

Bitte könnten Sie mir auch sagen, den kürzesten Weg zu drucken, mein experiment Werte bekommen und Ausgänge (mittels for-Schleife)? Wenn Sie können nicht dieses Problem beheben, bitte re-schreiben Sie den code für mich. Ich habe schonmal ein link, um diese Hausaufgaben Frage.
