Question

Draft a program that adds two BCD numbers (10-digits each). The first BCD number is stored in an array named myAuburnID, and the second in an array named myAurbunIdRev. The first number is your actual Auburn ID (with a prefix single zero digit and the remaining digits as the 9-digits of your Auburn ID); the second is the value of MyAuburnId written backwards. Your program should do the following: 1) Use shifts/rotates using myAuburnID to fill the array myAuburnIdRev 2) Display contents of the memory locations in question 3) Add myAuburnID and myAurbunIdRev using BCD arithmetic 4) Store the sum in a variable named Result, and 5) Display contents of memory post execution.
