Task Assembly programming
Write an assembly language program for the WASP processor using the Sting assembler.
Your assembly program should allow the user to encrypt a message using a Caesar Cipher.
A "Caesar Cipher" is a simple and wellknown way to encrypt text. To use it you first pick a number
called the "shift". For example, Then every letter in the message has that number added to it to
move it forward in the alphabet. For example, in this case, becomes becomes and
so on For numbers at the end of the alphabet, the letters start again from the beginning. In this
example the letter would become and the letter would become
Using a shift of the text YELLOW SUBMARINE becomes BHOORZ VXEPDULQH.
Your program will work as follows:
Allow the user to type in a single digit for the shift. The shift will be between and Your
program will store the number in a variable. You do not need to handle shifts larger than
The user will type text into the console. This will be converted to the encrypted text and
displayed on the screen.
The program will work for both upper and lowercase characters. The program will not
change spaces, digits, or other symbols.
The program will halt once it has displayed a line of text. Check for the new line character.
For example, if the user enters a shift of then enters "Good morning, Mr Turing!" your program
will display:
Nvvk tvyupun, Ty Abypun!
