What Do?

Vigenère cipher. In order to defeat a simple letter frequency analysis, the Vigenère cipher encodes a letter into one of several cipher letters, depending on its position
in the input document. Choose a keyword, for example TIGER. Then encode the first letter of the input text like this:

The encoded alphabet is just the regular alphabet shifted to start at ,
the first letter of the keyword . The second letter is encrypted
according to the following
map.


The
third, fourth, and fifth letters in the input text are encrypted using
the alphabet sequences beginning with characters , , and , and so on.
Because the key is only
five letters long, the sixth letter of the input text is encrypted in the same way as the first.
Write a program that encrypts or decrypts an input text according to this cipher.

school just started 2day for me

I wrote a java cipher decoder that does this for you about a year ago if you want it

unfortunately it has to be in C++ but thx anyways

I can help you add me on msn

How are you going to help him write an encryption/decryption program if you can't get a simple banking simulator working

wtf is this shit im so lost

because encryption/decryption is not so hard also that bank program was coded in C and i code in C++ so i was just trying it in C also if you want some snippets for your project message me.

The answer is 3.14
