Assmbly Language

# Description:
# This program reads series of temperature values greater than -40 (exclusive,
# so -40 is invalid temperature) and less than 140 (inclusive, so 140 is a valid
# temperature) and will stop reading when -1 is entered. if invalid temperature
# is entered then program prints an error message and rejects the number. in
# the end print the sum and count and also save the sum and count into static
# integer variables: sum_p and count_p
#
# *** temperature should be in range (-40, 140] and stop reading on -1
#
# Sample run:
# Enter a value greater than -40 and less than or equal to 140 (-1 to stop): -40
# Invalid entry
# Enter a value greater than -40 and less than or equal to 140 (-1 to stop): 140
# Enter a value greater than -40 and less than or equal to 140 (-1 to stop): 5
# Enter a value greater than -40 and less than or equal to 140 (-1 to stop): -1
# Sum: 145
# Count: 2

Explanation / Answer

.data
prompt_p: .asciiz "Enter a value greater than -40 and less than or equal to 140 (-1 to stop): "

sum_p: .asciiz "Sum: "
count_p: .asciiz "Count: "
invalid_p: .asciiz "Invalid entry "

nextline_p: .asciiz " " #

sum_var_p: .word 0 # initialize static variable sum_p to zero
count_var_p: .word 0 # initialize static variable count_p to zero

.text
main:

la $s0,promp_p

la $s1,count_p

$t2: .int -1
$t3: .int -40
$t4: .int 140

beq $s0,$t2,NOP

ble $s0,$t4,l1

l1: bne $s0,$t3,l2

l2: addi $t0,$t0,$s0

add $s1,1

bal invalid_p
