VC嵌入汇编如何识别指针

VC嵌入汇编怎么识别指针
那两个输出错误结果的语法是从书上看来的，书上运行的是MASM8.0，因为我找不到编译器同时也不会用，所以就只在VC2008里试验了

C/C++ code

void main(){    int *x = new int[5];    x[0] = 1;    x[1] = 12;    x[2] = 123;    x[3] = 1234;    x[4] = 12345;    int y = 789;    int a[] = {1,12,123,1234,12345};    int result1, result2, result3;    _asm    {        mov eax, y        //输出结果正确        mov result1, eax        mov eax, [x+2]    //输出结果错误        mov result2, eax        mov eax, [a+2]    //输出结果错误        mov result3, eax    }    cout<<result1<<endl;    cout<<result2<<endl;    cout<<result3<<endl;}

C/C++ code

#include <iostream.h>void main(){    int *x = new int[5];    x[0] = 1;    x[1] = 12;    x[2] = 123;    x[3] = 1234;    x[4] = 12345;    int y = 789;    int a[5] = {1,12,123,1234,12345};    int result1=0;    int result2=0;    int result3=0;    _asm    {        mov eax , y        //输出结果正确        mov result1 , eax    /*        xor eax , eax        mov eax , dword ptr [a+16] //这里对于a数组        mov result2, eax    */            xor eax , eax        mov eax , [ x ]        mov edx , [ eax + 2 * 4 ]        mov result2 , edx    }    cout<<result1<<endl;    cout<<result2<<endl;    cout<<result3<<endl;}
