我正在試圖做一個簡單的程序來計算字符串中的字符數。看起來我遵循結構,但我一直得到相同的錯誤地址錯誤,任何人都知道爲什麼?我不斷收到不良地址異常,任何知道爲什麼?
.data
array: .space 100
prompt1: .asciiz " Enter the string that you would like to reverse and calculate character: "
prompt2: .asciiz " "
.text
main:
la $a1, array # allocate the array space
ask:
li $v0, 4 # print String
la $a0, prompt1 # load prompt1
syscall
li $v0, 8 # read the string
syscall
move $a1, $v0 # move input to $a1
li $t0 ,0 # $t0 will hold the actual numbers of character in the string
loopCount:
lbu $t1, 0($a1) # load the next character into t1
beqz $t1, print # check for the null character
addi $a1, $a1, 1 # increment the string pointer
addi $t0, $t0, 1 # increment the count
b loopCount # return to the top of the loop
print:
li $v0, 1
move $a0, $t0
syscall
