再来看看相应的汇编码:
5: int a = 20;
00401028 mov dword ptr [ebp-4],14h
6: int & b = a;
0040102F lea eax,[ebp-4]
00401032 mov dword ptr [ebp-8],eax
7: b ++;
00401035 mov ecx,dword ptr [ebp-8]
00401038 mov edx,dword ptr [ecx]
0040103A add edx,1
0040103D mov eax,dword ptr [ebp-8]
00401040 mov dword ptr [eax],edx
8: printf("==== %d ====\r\n", b);
00401042 mov ecx,dword ptr [ebp-8]
00401045 mov edx,dword ptr [ecx]
00401047 push edx
00401048 push offset string "==== %d ====\r\n" (0042801c)
0040104D call printf (004012a0)
00401052 add esp,8
9: }
可以看出, 这两段汇编码完全一样.
