比如这样一个二维数组：
unsigned char DATA[][16] =
{
{0x20,0x04,0x20,0x04,0x22,0x42,0x22,0x82,0xFE,0x7F,0x21,0x01,0x21,0x01,0x20,0x10},
{0x20,0x10,0xFF,0x08,0x20,0x07,0x22,0x1A,0xAC,0x21,0x20,0x40,0x20,0xF0,0x00,0x00},
{0x80,0x00,0x40,0x00,0xF0,0x7F,0x1C,0x00,0x03,0x00,0xF0,0x7F,0x01,0x00,0x0E,0x00},
{0x04,0x00,0x00,0x00,0x04,0x00,0x04,0x20,0x04,0x40,0xFC,0x3F,0x00,0x00,0x00,0x00},
{0x20,0x00,0x20,0x80,0x20,0x40,0x20,0x20,0x20,0x10,0x20,0x0C,0xA0,0x03,0x7F,0x00},
{0xA0,0x01,0x20,0x06,0x20,0x08,0x20,0x30,0x20,0x60,0x20,0xC0,0x20,0x40,0x00,0x00},
{0x00,0x00,0x18,0x29,0x04,0x29,0x14,0x15,0x94,0x14,0x94,0x4A,0xD5,0x89,0xB6,0x44},
{0x14,0x3F,0x14,0x06,0x94,0x09,0x04,0x09,0x14,0x10,0x0C,0x30,0x04,0x10,0x00,0x00},
};
要用sizeof求其总的大小（不是到\0就结束那种）
方法，用sizeof
程序1：
1 2 3 4 5 | void disp()
{
printf("%d\n",sizeof(DATA));
system("pause");
}
|
返回正确结果：128
程序2:
1 2 3 4 5 | void disp(unsigned char s[][16])
{
printf("%d\n",sizeof(s));
system("pause");
}
|
返回结果：4
将sizeof(s)改为sizeof(*s)，返回结果16
问题：
因为现在必须要用指针，也就是程序2的形势。可是不知道哪里错了，是指针类型不对？还是其他原因？应该怎么改？
谢谢！
