Question

Write a MIPS program that reads (with an appropriate prompt) a sequence of 20 integers and stores them in an array, and then calls the following two functions and prints the results in a readable format. The two functions are:

smallestLargest: computes the smallest and the largest values in the array.

oddEven: computes the number of even integers and the number of odd integers.

Answer 1

.data
prompt: .asciiz "\nEnter a integer: " # It will use new line and enters the value
even_msg:.asciiz "\nThe number is even.\n" # for even
odd_msg: .asciiz "\nThe number is odd.\n # for odd
Result1: .asciiz "The smallest value in the array is "
Result2: .asciiz "The largest value in the array is "
Result3: .asciiz “Odd integer is”
Result3: .asciiz “Even integer is”
.text

main:
j loop

loop:
li $v0, 5 # Read in value
syscall
sw $v0,0($a1) # For storing the integer values
add $z0,$z0,-1 # For decrementing
add $a1,$a1,5 # For loading the address
add even_or_add # for odd or even integer
bgtz $z0 # For storing the next integer
li $t0,20
la $t1,array
j loop

smallestLargest:
lw $i0,0($a1)  
move $i1,$i0   
addi $a0,$a0,-1
blez $a0,ret1  

even_or_odd:
addi $a0, $zero,2 #for setting divisor 2
div $a0,$a0
mfhi $a0 #remainder
beq $a0,$zero,even
j odd

even:
la $a0,even_msg
li $v0,4
syscall
j return

odd:
la $a0,odd_msg
li $i0,4
syscall
j return

return:
j loop

exit:
