Question

Lab-3B Two-Way Branch

Write a MIPS program to read a positive integer and to determine and display whether it is an even number or odd.

A positive integer X is odd if its last digit is 1. Otherwise X is odd if X AND 1 is 1, or in other words X is even if X AND 1 is 0.

Example Input/Output

Give a positive number X= 41

X is an odd number

Give a positive number X= 40

X is an even number

Given below is the code for the question. Please do rate the answer if it helped. Thank you.

.data
   inMsg: .asciiz "Give a positive number X = "
   oddMsg: .asciiz "X is an odd number"
   evenMsg: .asciiz "X is an even number"

.text
   #print string
   li $v0, 4
   la $a0, inMsg
   syscall
  
  
   #read int
   li $v0, 5
   syscall
   move $t0, $v0
  
   and $t1, $t0, 1
   beq $t1, 1, odd
even:
   #print string
   li $v0, 4
   la $a0, evenMsg
   syscall
   b exit
odd:
   #print string
   li $v0, 4
   la $a0, oddMsg
   syscall

exit:
   #exit
   li $v0, 10
   syscall
