Write a Z$80$ assembly language program to evaluate the following expression:

W $=($X $+$ Y $$ P $+$ Q$)$:

The default output of the unmodified program file should show the following:

CS $333$ Lab #$2($Summer $2024)$

W: $0$

X: $0$

Y: $0$

P: $0$

Q: $0$

W $=($X $+$ Y $-$ P $+$ Q$)$

This indicates that all five program variables have been initialized to zero. $($The original expression is also printed for your reference.$)$

Open the program file for editing with a suitable text editor, such as Visual Studio Code. Look for the INSERT YOUR CODE HERE comment block in the program file; this is where you should begin adding your instructions to complete the program. The other code that is already provided in the file should not be changed.tart by assigning new values to the variables X$,$ Y$,$ P$,$ and Q$.$ You may choose any values you wish, but they must be unsigned eight$-$bit integers $($that is$,$ numbers up to $255)$; because these values are unsigned, you should also choose values that will cause the expression to evaluate to a positive result. This can be done by loading the new values into the accumulator, and then loading the accumulator into the variable using direct addressing mode. Next, supply the instructions which will evaluate the given expression and compute the final value of W$.$Assemble and run your program to test your results; when you are finished, confirm that the value of W has been computed correctly, given the initial values you chose for the other variables. $($Your program must actually compute this value! No credit will be given for submissions in which this value has been determined in advance and "hard$-$coded" into the program.$)$
