Zitat von Che Guevara

Aber Walze_1(26) wird doch noch vor Walze_1_inv(Walze_1(pointer_1)) beschrieben... Ich glaube, ich verstehe nicht, was du meinst..

Ich denke Du hattest während ich geantwortet hab' den Code geändert.
Der Code wie jetzt oben angezeigt funktioniert. Wo ist dann das Problem ?

**Che Guevara** · 12.09.2011, 11:59

Oh, tut mir leid, ich hättes dazu schreiben sollen!
Also bei mir funktionierts leider nicht, ab und zu stimmt der Ein- und Ausgangstext nicht überein. Bist du dir sicher, dass es funktioniert?

Zitat von Che Guevara

Also bei mir funktionierts leider nicht, ab und zu stimmt der Ein- und Ausgangstext nicht überein.

So steht's bei mir im Terminal des Simulators:

Dechiff: 4:20:8:8

Ausg: 16:21:8:13

Dechiff: 16:21:8:13

Ausg: 22:4:23:12
Chiff: 24:17:15:25
Dechiff: 22:4:23:12

Ausg: 21:16:15:5
Chiff: 12:24:23:16
Dechiff: 21:16:15:5

Ausg: 2:24:5:15
Chiff: 15:16:25:2
Dechiff: 2:24:5:15

Ausg: 7:18:1:10
Chiff: 1:7:18:20
Dechiff: 7:18:1:10

Ausg: 18:22:3:6
Chiff: 5:12:16:7
Dechiff: 18:22:3:6

Ausg: 23:8:1:6
Chiff: 13:9:18:7
Dechiff: 23:8:1:6

Ausg: 8:4:16:19
Chiff: 19:17:3:21
Dechiff: 8:4:16:19

Ausg: 4:25:3:13
Chiff: 16:13:16:1
Dechiff: 4:25:3:13

Ausg: 18:9:15:18
Chiff: 5:8:23:9
Dechiff: 18:9:15:18

**Che Guevara** · 12.09.2011, 12:24

Also ich teste gerade an der Hardware, und bei mir funktionierts nicht immer! Schon der zweite "zufällig" generierte Text "16:9:9:3" wird zu "16:9:15:18" ! Ich weiß aber nicht, worans liegt...
