Question
Instructions: write a code in MIPS that will display two user input integers along with their sum and difference. Problem: When reading the 2nd integer
Instructions: write a code in MIPS that will display two user input integers along with their sum and difference.
Problem: When reading the 2nd integer back, it reads it back 3 times (see screenshot). I am unable to identify the problem.
Screenshot:
How you can help: Please help me understand why it is repeating 3 times.
Code:
.data prompt1: .asciiz "Enter the first integer: " prompt2: .asciiz "Enter the second integer: " num1: .asciiz "The first number is: " num2: .asciiz " The second number is: " op1: .asciiz " The sum of both numbers is: " op2: .asciiz " The difference of both numbers is: "
# $s0 = first integer # $s1 = second integer # $s2 = location of sum # $s3 = location of difference
##################################### # Program ##################################### .text .globl main main:
la $a0, prompt1 li $v0, 4 # "Enter the first integer:" syscall

la $a0, prompt2 li $v0, 4 # "Enter the second number: " syscall
li $v0, 5 syscall # read integer move $s1, $v0

Thank you!
Console Enter the first integer: 13 Enter the second integer: 9 The first number is: 13 The second number is: 999 The sum of both numbers is: 22 The difference of both numbers is: 4Step by Step Solution
