Question $2$:

$(5+8+7=20$ Marks $)$

CO$2$

a$.$ Assume that your student ID is a Hexadecimal number and the first two

digits have been stored in the AL register and the last two digits in the BL

register. Now, determine the value stored in the destination for each line

of the following instructions.

i$.$e$.$ if your student ID is $201014071$then $Ax$ will hold $20H$ and $Bx$ will

hold $71H.$

Hints: The register only deals with Hexadecimal numbers.

b$.$ Suppose the summation $($Decimal$)$ of the first four digits of your student

ID has been stored in the CL register $($Hexadecimal$).$ Illustrate

step$-$by$-$step simulation for the following instructions.

c$.$ Write an assembly program to store the digits of your student ID in an

array and then display the summation of the numbers from that array.

Important information that must be followed : my student id is $201014071,$ so please do the math where Ax will hold $20$H and BX will holde $71$H
