Question

Write an Assembly program in MIPS that does the following:

- Ask to enter two integers
- Ask to choose which of the 4 operations user wants to perform.

The operations are listed as follows:

Addition
Subtraction
Multiplication
Division

- Perform the operation and display the result to the user
- Ask if the user wants to continue (C) or quit (Q). If the user chooses continue (C), steps should start over. Otherwise (Q) program ends.

Submit a screenshot of execution of your program for each operation. Also include your program source code together with a comment section in the beginning of your program that has your name, as well as a description about how to run your program.

Step-by-step explanation:

#DATA SECTION

.data

#Decalre x

x: .word 0

#declare y

y: .word 0

#Declare variables

choice: .space 1

#Store the repeat choice

op: .asciiz "C"

#Prompt

prompt1: .asciiz "\\Enter 2 integers:\\"

#Declare string for menu

menu: .asciiz "\\Menu \\ 1. Addition\\ 2. Subtraction \\ 3. Multiplication \\ 4. Division \\Enter your choice:"

#Declare string for repeat

repeat: .asciiz "\\Do u want to continue (C) or quit(Q):"

#Declare string for result

result: .asciiz "Result="
