Square code is a simple transposition cipher that utilizes a square (or rectangle) arrangement of your plain text to create a ciphertext. You will write a program that allows the user to type a message of any length, then encode it using an appropriately sized 2D array Requirements . Name the source file for your program program8.cpp . Prompt the user to type in a message - You must strip all whitespace and common punctuation marks Tabs, spaces, new lines, and carriage returns count as white space Period, comma, apostrophe, exclamation mark, and question mark count as com- mon punctuation . The message will then be inserted into a dynamic 2D array - The dynamic array will always have 12 columns - It is up to you to determine how many rows are required . You are only expected to encode the message . A sample run of your program shall look like NOTE: The message and encoded output are both just one line, breaks were added for visibility NOTE: The '# are actually in the array Enter a message to be encoded: good look at how he treats his inferiors, not his equals.
