ok i know this is the command for reading an integer but where does it read the integer from? I got a factorial program, heres the beginning of it:
.data
prompt: .asciiz "you want n! for which value of n?\n"
.align 4
n: .space4
i: .word 1
fact: .word 1
.text
.globl main
main:
li $v0, 4 #syscall code: print string
la $a0, prompt
syscall
li $v0, 5 #syscall code: read int
syscall
sw $v0, n
from my understanding, the program is meant to prompt u for a number and u enter a number and then the read int function will read tht integer and store it to address n. But how do i enter this number? i tried running this on SPIM(simulator for MIPS) and it just came out with a 0 everytime because apparently the read int is reading a 0?
