就教一下,下面这几行是什么意思.
unsigned char C0[10]={0x01,0x00,0x01,0x01,0x00,0x01,0x01,0x01,0x01,0x01}; unsigned char C1[10]={0x03,0x02,0x02,0x02,0x03,0x01,0x01,0x02,0x03,0x03}; unsigned char C2[10]={0x01,0x00,0x03,0x02,0x02,0x02,0x03,0x00,0x03,0x02}; unsigned char C3[10]={0x03,0x02,0x01,0x03,0x02,0x03,0x03,0x02,0x03,0x03}; |
