Project #$2$: Cryptography:

Design an assembly program to read a string from the user. Your program should encrypt the input string

according to the following encryption equation:

Encrypted letter $=(P+3)\%26$

Where:

Ensure that:

a$.$ Lowercase and uppercase letters will have the same P value.

b$.$ The encrypted letter must be written in the same case as the original letter.

c$.$ Special characters will not be encrypted.

Sample Execution:

Enter any string $($press enter to halt entry$)$: Experience is a GREAT teacher $!!$

The encrypted version is: Hashulhqfh Iv d JUHDW whdfkhu $!!$
