Question

Using MIPS, create a stack that takes user input until the user inputs 0, then output the characters that were entered onto the stack. Make sure to use $sp. Example:

Please enter a number. Press 0 to quit:

4

5

2

5

7

0

Your numbers were:

4

5

2

5

7

Answer 1

.data
input_prompt: .asciiz "Plese enter a number. Press 0 to quit:\n"
new_line: .asciiz "\n"
output_line: .asciiz "Your numbers were:\n"

.text

.globl main
main:
   li $v0, 4
   la $a0, input_prompt
   syscall
   addi $sp, -4
   move $s1, $sp
   li $s2, 0
input:
   li $v0, 5
   syscall
   move $t0, $v0
   beq $t0, 0, output1
   sw $t0, 0($sp)
   addi $sp, $sp, -4
   addi $s2, $s2, 1
   j input
output1:
   li $v0, 4
   la $a0, output_line
   syscall
output:
   beq $s2, 0, end
   lw $t0, 0($s1)
   li $v0, 1
   move $a0, $t0
   syscall
   li $v0, 4
   la $a0, new_line
   syscall
   addi $s2, $s2, -1
   addi $s1, $s1, -4
   j output
end:  
   li $v0, 10
   syscall
