Question

csc 220 assembly

2. Use the following code below as a template and follow the instructions written in the comments Assume I have the following data segment written: data val1 BYTE 10h val2 WORD 8000h val3 DWORD OFFFFh val4 WORD 7FFFh :1. Write an instruction that increments val2. ;2. Write an instruction that subtracts val3 from EAX. ;3. Write instructions that subtract val4 from val2. .code ;Write your instructions here

Answer 1

The INC (increment) adds 1 to a single operand

The SUB instruction subtracts a source operand from a destination operand.

SUB dest, source

So, Required instructions are as follows:

1. Incrementing val2

  INC val2;. //val2=8001h

2. Subtract val3 from EAX

SUB EAX, val3;

3. Subtract val4 from val2

MOV AX, val4;  //AX=7FFFh

SUB val2, AX;

Please give a thumbs up if you like the solution.
