[ASM] [Inc] Arrays and Strings

##output the contents of an "array" which you initialize via .byte, .word, .half

#then, input a string and output the string backwards

.data
string_array:
	.space 1000 #define an array 1000 bytes big

reverse_array:
	.space 1000 #define the array that will hold the reverse

.globl main
.text


main:

	la $a0, user_input #user input
	li $v0, 4
	syscall

	la $a0, string_array #prepare for user input into the string array
	li $a1, 1000 #telling it to feed it into those 1000 bytes of memory + 1(why +1?)
	li $v0, 8 #the actual syscall code
	syscall


	la $t0, string_array #set t1 to store an address of our string array
	la $t2, reverse_array #set t2 to be the address of our reverse array

repeat:

	lb $t1, ($t0) #store the BYTE indicated by the address in t0
	beqz $t1, finish #if the address becomes 0, terminate

	##get the maximium of the reverse array and feed byte by byte from the back-to-front



	addi $t0, $t0, 4 #increase the address by 4, which moves us to the next byte

finish:
	la $a0, terminate
	li $v0, 4
	syscall

	li $v0, 10
	syscall



.data

user_input:
	.asciiz "Input your string: "

terminate:
	.asciiz "Terminating the program."
