Code.org, Javacript Caesar Cipher

A Caeser cipher shifts each letter up a certain number of spaces up the alphabet to make it unreadable. To decode it you take away a number from the code to get back to the original message. The 3 Videos take you through how to make the screen, how to code the code button and how to code the decoding button.

Algorithm
Get message in upper case
loop for each letter in message
find ascii number for letter store in CC
if not a space CC!=32
add on a set number CC=CC+5
if CC>90 number is greater than 90 (Z)
take away 26 CC=CC-26
add charactor with number to the message
Display the cipher message
