Write an ASM program that evaluates the following expression, using variables: Z=(A-B)-(C-D) 1. Declare and initialize the memory variable A to 32-bit signed integer value -54: and variable B to 16-bit signed integer value -3210. 2. Declare the memory variables C and D and read in their values from the keyb as 32-bit signed integer value -43210 and 8-bit signed integer values -10 a. You should display a message asking for the value of the variable example: "What is the value of C?" then b. Read in the value of C from the keyboard and then c. Display the value you have read beside (ie, to the right of) the mes "What is the value of C?". Then repeat for variable D in the next line. 3. Variable Z should be declared as a 32-bit signed integer. 4. Display the string "Z = (A - B) - (C-D)" alone in a single line. 5. Display the values of all the variables A, B, C, D together in the next line (in order in which they appear in the expression); each separated by 3 spaces a semicolumn and 3 spaces again. 6. Display an empty line. 7. Display the final result contained in variable Z, in binary, then in decimal, and in hexadecimal; each in a separate line.
