Ok individually i can do both but im not sure where to start when putting these two together.
Bassically i want to read words from a text file then encrypt them in a two dimensional array.
So say the first word is MATHEMATICS id first want to remove the duplicated letters then place the remaining letters in a 5x5 array filling the rest of the space with the ramaining letters of the alphabet:
M A T H E
I C S B D
F G K L N
O P Q R U
V W X Y Z
The encryption would then be done by creating a rectangle so corners M and K. Then swap the letters on each corner so M would be T and F would be K
Hope this makes sense and any help is appreciated.
