Question

在汇编中如何打印数组的值？现在在这个程序中我还必须打印它的值<用户输入的索引。

.intel_syntax noprefix

.include "console.i"

.data

index:  .long 0
array:  .long 1,2,3,4,5,6,7,8,9,10,11,12                # Array initialized
value:  .long 0


.text

ask1:   .asciz          "Enter an Index: "
ans:    .asciz          "Value= "
ask2:   .asciz          "Invalid Index"
ask3:   .asciz          "Goodbye!!"


_entry:

        Prompt ask1
        GetInt index

        mov ebx, offset array                           # ebx = address of array

        mov esi, index  
        cmp esi, 11                                     # comparing index with 11

        ja  1f                                          # if Index > 11,then jump 
                                                        # to label 1

        mov eax, [ebx + 4*esi]

        mov value, eax

        Prompt ans
        PutInt value
        PutEol


        Prompt ask3
        PutEol
        ret

1:      Prompt ask2
        PutEol

        Prompt ask3
        PutEol
        ret

.global _entry

.end
