Question

Write an interactive program that inputs a decimal num1 and an integer num2. If num1 is less than num2, then it displays "num 1 is less than num 2"; if they are identical, it starts over again; if . If num2 is less than num1, then it displays "num 2 is less than num 1"

(((((((((((in MIPS assembly language)))))))))))

Answer 1

MIPS code to perform the given task is provided below, please comment if any doubts:

MIPS Code:

.data
    NUM1: .asciiz "Enter the NUM1: \n"
    NUM2: .asciiz "Enter the NUM2: \n"
    msg1: .asciiz "num 2 is less than num 1\n"
    msg2: .asciiz "num 1 is less than num 2\n"
main:
.text

LOOP:
   #the first number prompt
   la        $a0, NUM1
   li        $v0, 4
   syscall

   #read the num1
   li        $v0, 5
   syscall
   move     $t0,$v0

   #the second number prompt
   la       $a0, NUM2
   li       $v0,4
   syscall

   #read the num2
   li       $v0, 5
   syscall
   move     $t1,$v0

   #if num1 is greater than num2
   bgt      $t0,$t1, bigger1
  
   #if num2 is gretaer
   bgt      $t1,$t0, bigger2

   #if equal display loop forever
  
   b        LOOP
  
bigger1:
   #display the message
   la        $a0, msg1
   li        $v0, 4
   syscall
   b exit
  
bigger2:
   #display the message
   la        $a0, msg2
   li        $v0, 4
   syscall  

#exit code
exit:
   li       $v0,10
   syscall

Output test:
