part 1 is the most important and it is written in assembly language please
Hint: Instead of a 26-part if/elseif/lelse statement, a much better way is to subtract the value of 'A'from whichever letter you have in the key to get the shift value. The complete example, along with its ciphertext is given below: OPENSESAMEOPENSESAMEOPENS Key: Plaintext MEETUSATTWELVEOCLOCKSHARP Ciphertext: ATIGMWSTFASAZRGGDO0OGWEEH After collecting the key and the plaintext from the user, your program will output the ciphertext to the console Note: You can limit the length of these strings to 100 characters in your program, and you do not have to handle the case when the user types more than 100 characters. You can also limit the string to only uppercase letters (as shown in the examples), to mlake the logic simpler. If there are no spaces, that also rneans that you can use scanf ( "%s" , str) to enter the string(s) Sample Output Enter the message: MEETUSATTWELVEOCLOCKSHARP Enter the key: OPENSESAME Encrypted message: ATIGMWSTFASAZRGGDOOOGWEEH decrypt.asm This program will do the opposite of encrypt.asm. It will apply the Vigenre cipher in reverse. It wil subtract the offset from the ciphertext characters, producing the plaintext. Sample Output Enter the encrypted message: ATIGMWSTFASAZRGGDO00GWEEH Enter the key: OPENSESAME Decrypted message: MEETUSATTWELVEOCLOCKSHARP Note: For the purposes of this assignment, you can limit the strings to 50 characters (51, including the null byte) Part 2 (4 marks) For this part of the assignment, you can create any assembly language program that you like. Suggested ideas include (but are not limited to) A number guessing game A question/answer program that collects statistics on yeso answers A program that sorts a list of numbers, entered by the user, and outputs them Hint: Instead of a 26-part if/elseif/lelse statement, a much better way is to subtract the value of 'A'from whichever letter you have in the key to get the shift value.
