我是汇编的新手,我正在尝试制作一个输出用户字符串后缀的程序。我也想在任何时候用户输入内容时都这样做,它会以随机颜色输出反转的字符串。但我不知道该怎么做。有人可以为我做这个代码或告诉我在哪里修改代码?非常感谢你。

INCLUDE Irvine32.inc

.data

stringInput byte 50 dup(0)

promptIn byte "Enter the string: ",0

.code

swaping MACRO a,b

XOR a,b

XOR b,a

XOR a,b

ENDM

strlen proc

push ebp

mov ebp, esp

push ebx

mov eax, 0

mov ebx, [ebp+8]

Counter:

cmp byte ptr [ebx + eax], 0

je Done

inc eax

jmp counter

Done:

pop ebx

mov esp, ebp

pop ebp

ret TYPE ebp

strlen endp

strrev proc

Push ebp

MOV ebp, esp

Push eax

Push ebx

Push ecx

Mov ebx, [ebp+8]

Mov ecx, [ebp+8]

push ebx

call strlen

ADD ecx, eax

SHR al,1

count: CMP al,0

JZ finished

MOV ah, byte PTR [ebx]

swaping ah, byte ptr [ecx-1]

MOV BYTE PTR [ebx], ah

INC ebx

DEC ecx

DEC al

JMP count

finished: POP ecx

POP ebx

POP eax

MOV esp, ebp

POP ebp

RET (TYPE ebp)*4

strrev ENDP

main proc

mov eax, 0

mov edx, offset promptIn

call writeString

mov edx, offset stringInput

mov ecx, 51

call readString

push edx

call strrev

call crlf

call writestring

call crlf

exit

main endp

end main
