Question

char temp[10];
_itoa(crc,temp,16);
strcat(buf,temp);

Answer 1

如
void CKjyView::OnDraw(CDC* pDC)
{
CKjyDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
WORD crc=0xd01b;
         char* buf="123456ggh";
CString kk;
kk.Format("%s%x",buf,crc);
pDC->TextOut(100,200,kk);
}

Answer 2

word crc=0xd01b;
char temp[10];
_itoa(crc,temp,16);
运行时出错
word crc=0x20;
char temp[10];
_itoa(crc,temp,16);
就不会!why?
