Question

Hello, this is a 2 part question for my beginning assembly class. Thank you in advance for your help

Boolean Calculator (1)

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 Program

When the user makes a choice, call a procedure that displays the name of the operation about to be performed.

Boolean Calculator (2)

Continue the solution program from the preceeding exercise by implementing the following procedures:

- AND_op: Prompt the user for two hexadecimal integers. AND them together and display the result in hexadecimal.

-OR_op: Prompt the user for two hexadecimal integers. OR them together and display the result in hexadecimal.

- NOT_op: Prompt the user for two hexadecimal integers. NOT the integer and display the result in hexadecimal.

- XOR_op: Prompt the user for two hexadecimal integers. Exclusive-OR them together and display the result in hexadecimal.

The following is what our professor has given us help with:
