-- program is finished running (dropped off bottom) --
This is my code
.data
array: .space 12 # Reserve 12 bytes of memory for the array
.text
la $t0, array # Load the address of the array into $t0
li $v0, 4 # System call code for printing a string
la $a0, prompt # Load the address of the prompt string
syscall # Print the prompt
.data
prompt: .asciiz "Enter three integers: "
li $v0, 5 # System call code for reading an integer
syscall # Read the first integer
sw $v0, 0($t0) # Store the first integer in the first word of the array
li $v0, 5 # Read the second integer
syscall
sw $v0, 4($t0) # Store the second integer in the second word of the array
li $v0, 5 # Read the third integer
syscall
sw $v0, 8($t0) # Store the third integer in the third word of the array
lw $t1, 0($t0) # Load the first integer into $t1
lw $t2, 4($t0) # Load the second integer into $t2
lw $t3, 8($t0) # Load the third integer into $t3
add $t4, $t1, $t2 # Add the first two integers and store the result in $t4
add $t4, $t4, $t3 # Add the third integer and store the result in $t4
sw $t4, sum # Store the sum in memory
.data
sum: .word 0
li $t5, 3 # Load the value 3 into $t5
div $t4, $t5 # Divide the sum by 3 to get the average
mflo $t4 # Store the result of the division in $t4
sw $t4, avg # Store the average in memory
.data
avg: .word 0
li $t0, 3 # Load the value 3 into $t0
li $t1, 0 # Load the value 0 into $t1
loop:
lw $t2, 0($t0) # Load the next integer from the array into $t2
add $t1, $t1, $t2 # Add the current integer to the sum
addi $t0, $t0, 4 # Move to the next word in the array
