Hey,
Ich möchte eine Datei mit dem Namen "Highscore" anlegen. Jedoch muss der Wert "gewonnen" bzw. "verloren" nach jedem Spiel geändert werden. Nun leider verstehe ich momentan einfach nicht wieso mein Sourcecode nicht klappt.
Ich bedanke mich schon einmal für jegliche Hilfe!
Datenordnung innerhalb der Datei:
Name(Win|Lose)
Max(0|1)
Peter(1|0)
...
Strukogramm:
Die Klasse zum auslesen und schreiben der Datei.
