int a,i=0; a=++i;汇编代码如下：

int a,i=0;
01221A4E mov dword ptr [i],0
a=++i;
01221A55 mov eax,dword ptr [i]
01221A58 add eax,1
01221A5B mov dword ptr [i],eax
01221A5E mov ecx,dword ptr [i]
01221A61 mov dword ptr [a],ecx

int a,i=0; a=i++;汇编代码如下：

int a,i=0;
009E1A4E mov dword ptr [i],0
a=i++;
009E1A55 mov eax,dword ptr [i]
009E1A58 mov dword ptr [a],eax
009E1A5B mov ecx,dword ptr [i]
009E1A5E add ecx,1
009E1A61 mov dword ptr [i],ecx
