汇编语言程序设计：[4]数字平台长度

1、打开masm汇编编译程序，新建一个masm源文件脚本。DATAS SEGMENT ;此处输入数据段代码 DATAS ENDSSTACKS SEGMENT ;此处输入堆栈段代码STACKS ENDSCODES SEGMENT ASSUME CS:CODES,DS:DATAS,SS:STACKSSTART: MOV AX,DATAS MOV DS,AX ;此处输入代码段代码 MOV AH,4CH INT 21HCODES ENDS END START

2、在正文中输入我们的程序代码，并将文件命名为jisuan.asmdata segmentobf db '***** xi锾攒揉敫aobo welcome you !***** Designed by 1wangxiaobo@163.com',0dh,0ah db ' input data:','$'a0 db ?a1 db ?b0 db ?b1 db ?a db ?b db ?data endsstack segment stack db 200 dup(0) stack endscode segment assume cs:code, ds:data,ss:stackmain:mov ax, data mov ds, ax mov ah, 9 lea dx, [obf] int 21h inc dx mov dl, 13 mov ah, 2 int 21h mov dl,10 int 21h mov ah,1 int 21h cmp al, 13 jz lab1 mov [a0], al mov [a], al mov [a1], 1x1: mov ah, 1 int 21h cmp al, 13 jz lab1 mov [b], al mov bl, [b] cmp bl, [a] jnz x2 add [a1], 1 jmp x1x2: mov [b0], bl mov [b1], 1x3: mov ah, 1 int 21h mov [a], al cmp bl,[a] jnz x4 add [b1],1 jmp x3x4: mov cl, [b1] cmp cl, [a1] jb y1 mov cl, [b0] mov [a0], cl mov cl, [b1] mov [a1],cly1: cmp al, 13 jz lab1 mov [b0], al mov [b1], 1 mov [b], al mov bl, [b] jmp x3lab1: mov ah, 2 mov dl,13 int 21h mov dl,10 int 21h cmp [a1],10 jb z1 mov ah,0 mov al, [a1] mov bl, 10 div bl add ax, 3030h mov bx, ax mov ah, 2 mov dl, bl int 21h mov dl, bh int 21h jmp z2z1: add [a1], 30h mov dl, [a1] int 21h sub [a1],30hz2: mov ah,2 mov dl, 13 int 21h mov dl, 10 int 21h mov cx, 0 mov cl, [a1] mov ah, 2m: mov dl,[a0] int 21h loop m mov ah, 4ch int 21hcode ends end main

3、运行我们编辑的文件,计算数字平台长度的程序，如：运行时输入：111122333，结果为: 4　　　　　　　　 1111***** xiaobo welcome you !***** Designed by 1wangxiaobo@163.cominput data:11112233341111Press any key to continue
