IN ASSEMBLY LANGUAGE USING MIPS IN MARS

.data

prompt1: .asciiz "\nMinimum number is : "
prompt2: .asciiz "\nRange of the array is : "
size: .word 10

#load array
array: .word 23, -12, 45, -32, 52, -72, 8, 13,22,876

.text

Answer 1

Please find the code below:

.data
prompt: .asciiz "\nMaximum number is : "
prompt1: .asciiz "\nMinimum number is : "
prompt2: .asciiz "\nRange of the array is : "
max : .float 9999
zero : .float 0
size: .word 10

#load array
array: .float 23.5, -12.5, 945.5, -32.5, 52.5, -172.5, 8.5, 13.5,22.5,876.5

.text
#load address of array and size
la $s4,array #load address of A
lw $t0,size #load i to t0

jal getArrayRange

li $v0, 4   
la $a0, prompt2 #prompt for string
syscall

li $v0,2
mov.s $f12,$f2
syscall

li $v0, 10 #terminate
syscall

getArrayRange:
l.s $f1,max
l.s $f0,zero
l.s $f2,zero

loop:

mul $t1,$s2,4 #get index of first element by multiplying it by 4
add $t1,$t1,$s4 #add index to base address of array
l.s $f3,0($t1) #load base address to f0

#check for minimum
c.lt.s $f0,$f3
bc1t skip
j next
skip:
mov.s $f0,$f3
next:
#check for maximum
c.lt.s $f1,$f3
bc1t skip1
mov.s $f1,$f3
skip1:

addi $s2,$s2,1 #increase i by one
blt $s2,$t0,loop # loop until size

li $v0, 4   
la $a0, prompt #prompt for string
syscall

li $v0,2
mov.s $f12,$f0
syscall

li $v0, 4   
la $a0, prompt1 #prompt for string
syscall

li $v0,2
mov.s $f12,$f1
syscall

sub.s $f2,$f0,$f1
jr $ra

output:
