Question

I am using Xcode on Mac OS with 32-bit Intel architecture and need help with the following written in assembly language

Create a program for GAS that contains the following items:

-A sum variable of the appropriate size to hold initializer 0x10000

-A message variable that holds the text (preserving line breaks): Welcome to Assembly programming. Your grade will be randomly assigned by the Intel 8086 processor!

-An input variable that does not contain an initial value and is able to hold the values 0-255

-An instuction to assign the base-10 value 200 to the input variable as a binary literal

Explanation / Answer

1- This program gives you idea about how to prompts the user to enter an integer and returns the integer value entered via the EAX register. The prompt string should be passed to the proc as an argument using the stack. The prompt should be displayed using the strput.

.386

.MODEL flat,stdcall

.STACK 4096

;; change the IRVINE32 direction if it is not installed in the bellow folder

INCLUDE      C:IrvineIrvine32.inc

INCLUDELIB   C:IrvineIrvine32.lib

.data

prompt BYTE "Enter the integer: ", 0

.code

qryInt PROC

    push ebp

    mov ebp, esp

    mov edx, [ebp + 8] ; get the address of the prompt parameter

    call WriteString

    call ReadInt ; read the integer into EAX

    pop ebp

    ret

qryInt ENDP

main PROC

    ; put the address of the prompt onto the stack

    mov eax, OFFSET prompt

    push eax

    call qryInt

    ; the integer should be EAX

    call WriteInt

    exit

main ENDP

END main

2- This program takes a single string argument, counts the number of characters in the string, and returns the count via the EAX register.
