Write a utility that accepts an "outbox" folder, "encrypted" folder, and "publickey" file. When a FILENAMEp shows up in the "outbox" folder, your utility will encrypt the FILENAME using the public key and place it into the "encrypted" folder. Your utility then verifies that the encrypted file was created successfully (length is not zero, and there were no errors such as running out of disk space, etc.), your utility creates FILENAMEp file in the "encrypted" folder, and erases the FILENAMEp and FILENAME from the "outbox" folder. You then loop thorugh the "outbox" folder and erase all files (those without the p) with create date older than 30 days.

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
