Write a MIPS program to \"guess a number\". Specification Create a variable call

Question

Write a MIPS program to "guess a number". Specification Create a variable called numToGuess and set it equal to your number to guess. Pass a number entered from the keyboard to a procedure that prints one of the following messages: If the number from the keyboard equals the number to guess, print a "good guess" message. If the number from the keyboard is smaller than the number to guess, print a "too low" message. If the number from the keyboard is greater than the number to guess, print a "too hi" message. and returns 1 for a "good guess" or 0 for a "too low" or "too hi" guess. Allow no more than 5 guesses. If the number is guessed correctly before the 5th guess, print a congratulatory message and exit the program. If the number is not guessed correctly in five guesses, print a "you had your five guesses" message and exit the program.

.data
numToGuess: .word 8
lowMsg: .asciiz "too low"
highMsg: .asciiz "too high"
goodMsg: .asciiz "good guess"
winMsg: .asciiz " congratulations! you got it within 5 guesses"
lostMsg: .asciiz " you had your five guesses"
prompt: .asciiz " enter a number: "
.text
li $s0, 1

loop:
bgt $s0, 5, lost

li $v0, 4
la $a0, prompt
syscall

#read number from keyboard
li $v0, 5
syscall
move $t1, $v0

#setup parameter and call procedure
move $a0, $t1
jal checkGuess

beq $v0, 1, won #chck return value if 1, then guess is correct
add $s0, $s0, 1 #increment counter
j loop

won:
li $v0, 4
la $a0, winMsg
syscall
b exit

lost:
li $v0, 4
la $a0, lostMsg
syscall
exit:
#exit
li $v0, 10
syscall

#=================================
#procedure to check user guess and print message, return 1 if good guess and 0 otherwise
#receives the user guess as argument
checkGuess:
lw $t0, numToGuess
beq $t0, $a0, equal
bgt $a0, $t0, higher

li $v0, 4
la $a0, lowMsg
syscall
li $v0, 0
jr $ra

higher:
li $v0, 4
la $a0, highMsg
syscall
li $v0, 0
jr $ra
equal:
li $v0, 4
la $a0, goodMsg
syscall
li $v0, 1
jr $ra
