Question

In assembly language:

Boolean Calculator

Create a program that functions as a simple Boolean calculator for 32

bit integers. It should display a menu that asks the user to make a

selection from the following list:

1. x AND y

2. x OR y

3. NOT x

4. x XOR y

5. Exit the program

The program should run in a loop. When the user makes a choice, call

a procedure called ChooseProcedure which invokes the appropriate

procedure to perform the logical operation as outlined below:

AND_op : Prompt the user for two hexadecimal integers . AND them

together and displays the result in hexadecimal.

OR_op : Prompt the user for two hexadecimal integers . OR them

together and displays the result in hexadecimal.

NOT_op : Prompt the user for a hexadecimal integer . NOT the integer

and displays the result in hexadecimal.

XOR_op : Prompt the user for two hexadecimal integers . XOR them

together and displays the result in hexadecimal.

Error checking : Your program should check for valid menu selection.

In case of invalid selection, it will do nothing but will continue waiting

for input.

Implement the program with case table

Explanation / Answer

Pleaee find below the BooleanCalculator assembly code using case table: INCLUDE Irvine32.inc .data caseTable byte '1' ;lookup value dword Process_1 ;address of lookup value entrySize = ($ - caseTable ) byte '2' dword Process_2 byte '3' dword Process_3 byte '4' dword Process_4 byte '5' dword Process_5 numberOfEntries = 5 msgIntro byte "This is Your Name's fourth assembly program which will later",0dh,0ah byte "function as a simple boolean calculator for 32-bit integers.
