打印汇编变量C++
大家好! 我正在进行MASM课程,并且开始了这项练习。 我有一个简单的汇编代码:
.386
.model flat,c
.data
quote byte "Machines do feel", 0
message byte SIZEOF quote DUP(0),0
.code
start proc
mov esi,0
mov ecx,SIZEOF quote
LP:
mov al,quote[esi]
mov message[esi],al
inc esi
loop LP
ret
start endp
end
我想编写一个可以“ printf“变量”消息”的C ++程序。
我该怎么做?
我尝试添加:
mov eax, DWORD ptr [message]
在“ .ASM”文件中以存储消息变量的地址在功能返回的寄存器上,然后我编写了此程序来尝试打印值:
#include <iostream>
extern "C" char *start();
int main(){
char *message = start();
for(int i = 0x0; i < sizeof(message)/sizeof(char); i++){
printf("%s", message[i]);
}
return 0x0;
}
但是当我尝试运行它时,我得到了错误:
Unhandled page fault on read access to 6863614D at address 0040162E (thread 0024), starting debugger...
0024:err:seh:start_debugger Couldn't start debugger L"winedbg --auto 32 68" (2)
您能解释一下我如何打印“ .ASM”文件“消息”变量的值? 还可以向我展示不同的方法吗?
非常感谢您,编码不错!
Hello All!
I'm doing a MASM course and I got into this exercise.
I have this simple assembly code:
.386
.model flat,c
.data
quote byte "Machines do feel", 0
message byte SIZEOF quote DUP(0),0
.code
start proc
mov esi,0
mov ecx,SIZEOF quote
LP:
mov al,quote[esi]
mov message[esi],al
inc esi
loop LP
ret
start endp
end
And I want to write a C++ program that can "printf" the variable "message".
How can I do this?
I tryed to add:
mov eax, DWORD ptr [message]
To the ".asm" file to store the address of the message variable on the register returned by the function and then I wrote this program to try to printf the values:
#include <iostream>
extern "C" char *start();
int main(){
char *message = start();
for(int i = 0x0; i < sizeof(message)/sizeof(char); i++){
printf("%s", message[i]);
}
return 0x0;
}
But when I try to run it I get the error:
Unhandled page fault on read access to 6863614D at address 0040162E (thread 0024), starting debugger...
0024:err:seh:start_debugger Couldn't start debugger L"winedbg --auto 32 68" (2)
Can you please explain me how can I print the values of the ".asm" file "message" variable?
And can also show me different methods to do this?
Thank you so much, have a nice coding!
