以较大整数的格式中断打印数组

Question

我有一个包含斐波那契数列的数组。当我打印内容时，我的格式是：

array[0] = 1

...

array[4] = 5

...

所以除了打印数组的内容之外，我还为 "array[" 打印了一条消息，然后是索引只是打印一个寄存器计数器，然后是最后一部分“] =”，然后我打印数组的值。对于大于 6 的大小，这不起作用，特别是后面的部分“] =”不打印并且数组的值被连接到索引。

这是打印值的代码：

.data
    arrayF: .word # starting address of array
    prompt: .asciiz "Enter value of N: "
    stringPartTwo: .asciiz "] = "
    stringPartOne: .asciiz "array["

.text
    start:
        # for printing the prompt
        li $v0, 4
        la $a0, prompt
        syscall

        # getting N from user
        li $v0, 5
        syscall
        move $t0, $v0 # putting N's value in $t0

        # Loading the beginning address of array into $a1 and $a2
        la $a1, arrayF
        addi $t1, $zero, 0 # A[i - 2]
        addi $t2, $zero, 0 # A[i - 1]
        addi $t3, $zero, 1 # A[i]
        addi $t4, $t0, 0 # Saves size of array in another register for later subroutine


   loop1:
        beq $t0, 0, done # Checking if size reached to 0
        subi $t0, $t0, 1 # Decrementing size for next iteration
        sw $t3, ($a1) # Storing A[i] in the array
        addi $a1, $a1, 4 # Accessing next element in array
        addi $t1, $t2, 0 # Moving A[i - 1] to A[i - 2] 
        addi $t2, $t3, 0 # Moving A[i] to A[i - 1]
        add $t3, $t2, $t1 # Calculating new A[i] 
        j loop1

    done:
        la $a1, arrayF # Loading base address
        addi $t1, $zero, 0 # Counter for subroutine

   loop2:
        beq $t1, $t4, finish # done printing if reached array's length
        lw $t2, ($a1) # loading the value in A[i] to $t2

        # printing "array["
        li $v0, 4
        la $a0, stringPartOne
        syscall

        # print index
        li $v0, 1 
        move $a0, $t1
        syscall 

        # printing "] = "
        li $v0, 4
        la $a0, stringPartTwo
        syscall

        # print value of array
        li $v0, 1 
        move $a0, $t2
        syscall 

        # printing new line
        addi $a0, [=10=], 10     #put newline in a0
        addi $v0, [=10=], 11     #print character in a0
        syscall


        addi $t1, $t1, 1 # incrementing counter
        addi $a1, $a1, 4 # accessing next element
        j loop2

您只为数组分配了 space 的一个字（4 个字节）。尝试存储更多的内容将首先覆盖 prompt，然后是 stringPartTwo 和 stringPartOne，具体取决于您尝试存储的字数。

您需要为数组分配更多内存，例如：

arrayF: .space 64   # allocate 64 bytes (16 words)
