Ok, something very wrong is going on with my program. When i run it the numbers it is giving me are sometimes right but are also wrong. H (the first letter in the word) is both = to 0 and 1 (wtf?). Any ways below i'll show you want i should be getting and what i am getting.
Book File (12 characters) Hello world! Message File (12 characters) Hello world! Out File (generated from the encoder, should be 12 numbers) 0 1 2 3 4 5 6 7 8 9 10 11 when the out file is decoded it should be the same as the message file.
this is what I'm getting:
Book File (12 characters) Hello world! Out File (generated from the encoder, should be 12 numbers) 1 3 9 7 5 6 7 9 10 11 when decoded this comes out to: Hlrwo wrldd please help me find out whats causing this problem!
Below is my code for each program.
