汇编冒泡排序，数组题

Posted 2021-07-07 Afololer

数组题

• cx应为长度-1
• 二层循环要保存cx,si

把数组中的0去掉，其他往前移动，最后面补0

DATAS SEGMENT
    ;此处输入数据段代码  
    ar db 6,33H,30H,30H,33H,30H,33H,'$'
DATAS ENDS

STACKS SEGMENT
    ;此处输入堆栈段代码
STACKS ENDS

CODES SEGMENT
    ASSUME CS:CODES,DS:DATAS,SS:STACKS
START:
    MOV AX,DATAS
    MOV DS,AX
    mov si,1
    mov cl,ar
    dec cl
L1:
   

    PUSH SI
    push cx
L2:
    mov bl,ar[si]
    cmp bl,30H
    jnz l3 ;不是0
    xchg bl,ar[si+1]
    mov ar[si],bl
L3:
    inc si
    LOOP l2
    pop cx
    POP SI

    
    loop L1


    lea dx,ar+1
    mov ah,9
    int 21H
    ;此处输入代码段代码
    MOV AH,4CH
    INT 21H
CODES ENDS
    END START
