C 語言小叮嚀

REMEMBER: the precedence of bitwise operators (not including shift operators) is lower than that of relational & equality operators! For example:

if (r.bytes[0] & 0xF0 == 0xB0)

is actually

if (r.bytes[0] & (0xF0 == 0xB0))

instead of

if ((r.bytes[0] & 0xF0) == 0xB0)

不過除這隻蟲也不會太難就是了 XD。
