00401028   mov         dword ptr [ebp-4],offset string "abcd" (0042201c)
5:        char q[10]="abcd";
0040102F   mov         eax,[string "abcd" (0042201c)]
00401034   mov         dword ptr [ebp-10h],eax
00401037   mov         cl,byte ptr [string "abcd"+4 (00422020)]
0040103D   mov         byte ptr [ebp-0Ch],cl
00401040   xor         edx,edx
