Question

write a program that takes twoinput values from the user and calculate the subtraction if the first number is greater than the second one other wise calculate the summation in MIPS

Answer 1

.data

message1:.asciiz"enter number 1"
message2:.asciiz"enter number 2"
message3:.asciiz"the sum is: "
message4:.asciiz"the difference is:"

.text

main:
#enter the input by the user
li $v0,4
la $a0,message1
syscall

#read the user input
li,$v0,5
syscall

#store the enteres value in the register
move $t0,$v0

#enter the input by the user
li $v0,4
la $a0,message2
syscall

#read the user input
li,$v0,5
syscall

#store the enteres value in the register
move $t1,$v0

#compare the values stored in the register

bgt $t0,$t1,difference
add $t3,$t0,$t1
li $v0,0
la $a0,message3
syscall
move $a0,$t3

difference:
sub $t3,$t0,$t1
li $v0,0
la $a0,message4
syscall
move $a0,$t3
