loops - Vigenere Cipher in C: Incomplete Encryption -

-
a general explanation of vigenere cipher: the vigenere cipher method of encryption similar caesar cipher. cipher takes in word argument , interprets alphabets of word follows- 0, b 1, c 2 , on. so if input key abc , want "hi hello" encrypted, output entail h remaining same, shifting 1 place, h shifting 2 places, e again remaining same (as being shifted 0), l shifting 1 place, other l 2 , on forth. the basic idea each letter shifts corresponding letter in argument , spaces , other punctuation marks ignored. if argument shorter message (as in cases), argument loops around message. my problem: my message being encrypted first alphabet of vignere cipher. for example, ./vc bc ----> message: abcde abcde becomes bcdef bcdef . in other words, entire message being shifted value of b when should instead shifted value of bc (+1 first alphabet , +2 every other alphabet.) i don't understand why happening despite being within loop. code: # include <cs5...
