Write a program in assembly language that will

- read in four integers

you will need to call the routine ReadInt four times

one number per line

this routine reads a value from the keyboard and stores it in EAX

call ReadInt

mov Num, eax

- if the integers are A, B, C, and D, compute

A - B + C - D

(Note: C is a reserved word so you cannot use it as an identifier!)

- print out the integers and the result

use the routine WriteInt which will display the contents of the register EAX on the screen as a signed decimal

mov eax, Num

call WriteInt

Use the following set of integers (in decimal):

42, -5, -23, 35

Use only the instructions covered so far. (Don't use looping!)
