小弟初学汇编,想写一个简单的输入字符串1和字符串2,查找字符串1是否包含字符串2
附上代码data segment
buf1 db 50 dup('$') ;最大字符数50
buf2 db 20 dup('$') ;查找最大字符数20
tishi1 db 'Please input the string:',0dh,0ah,'$'
tishi2 db 'Please input the string you want to find:',0dh,0ah,'$'
tishi3 db 'Find:','$'
tishi4 db 'Not Find:','$'
data ends
code segment
assume cs:code, ds:data
start: mov ax,data
mov ds,ax
mov cx,0
mov bx,0
mov si,2
mov di,2
- lea dx,tishi1
- mov ah,09h
- int 21h ;输出提示1
-
- lea dx,buf1
- mov ah,0ah
- int 21h ;输入字符串
-
- mov dl,0ah
- mov ah,02h
- int 21h ;回车换行
-
- lea dx,tishi2
- mov ah,09h
- int 21h ;输出提示2
-
- lea dx,buf2
- mov ah,0ah
- int 21h ;输入字符串
-
- mov dl,0ah
- mov ah,02h
- int 21h ;回车换行
-
-
- lea si,buf1+2
- lea di,buf2+2
- mov ax,0
- jmp z
x: inc cx
inc di
y: inc si
z: mov ah,buf1[si]
mov al,buf2[di]
cmp al,'$'
je yes
cmp ah,al
je x
- cmp ah,'$'
- je no
- sub si,cx
- sub di,cx
- mov cx,0
- jmp y
yes:
lea dx,tishi3
mov ah,09h
int 21h ;输出提示3
- lea dx,buf2+2
- mov ah,09h
- int 21h
-
- mov dl,0ah
- mov ah,02h
- int 21h ;回车换行
- jmp exit
no:
lea dx,tishi4
mov ah,09h
int 21h ;输出提示4
- lea dx,buf2+2
- mov ah,09h
- int 21h
-
- mov dl,0ah
- mov ah,02h
- int 21h ;回车换行
exit: mov ah,4ch
int 21h
code ends
end start
比如输入123412
123
为什么都是not find?
