以下是汇编实现输入字符串,显示对应字符串各个字符的ASCII码的代码:
```
; Declare data segment
data segment
input db 100 dup('$') ; 100 bytes for input string
output db 100 dup('$') ; 100 bytes for output string
len db 0 ; length of input string
newline db 0dh,0ah,'$' ; newline character
data ends
; Declare code segment
code segment
assume cs:code, ds:data
start:
; Initialize data segment
mov ax, data
mov ds, ax
; Display prompt
mov ah, 09h
mov dx, offset prompt
int 21h
; Read input string
mov ah, 0ah
mov dx, offset input
int 21h
; Calculate length of input string
mov cl, input+1 ; Length stored in second byte of input string
sub cl, '0' ; Convert ASCII character to decimal
mov len, cl
; Iterate over input string
mov si, offset input+2 ; Start at third byte of input string
mov di, offset output ; Output to output string
loop:
mov al, [si] ; Load character from input string
mov [di], al ; Save character to output string
inc di ; Move to next byte in output string
; Display ASCII code of character
mov ah, 02h ; Function to display character
mov dl, al ; ASCII code of character to display
int 21h ; Display character
; Move to next byte in input string
inc si
loop loop
; Display newline character
mov ah, 09h
mov dx, offset newline
int 21h
; Terminate program
mov ah, 4ch
int 21h
prompt db 'Enter a string: $'
code ends
end start
```
