Answer 2

case後面衹能寫整型或字符型變量或表達式，這與vb的select case是不一樣的

Answer 3

if (aa==true)
bb=1
else
bb=0
加个变量不就行了吗

Answer 4

if else
eles if
else

Answer 5

用多个 if else 来表达吧

Answer 6

chenghao = grade >=20000 ? "独孤求败" : (grade <= 500 ? "初学弟子" : ( grade<=1000?"初入江湖":(grade<=2000?"江湖少侠":(grade<=3500?"江湖大侠":(grade<=5500?"江湖豪侠":(grade<=8000?"一派掌门":(grade<=11000?"一代宗师":(grade<=15000?"武林盟主":"隐士")))))) ));
我没测试
不过这种写法不如用if else哈哈，我这样写是觉得好玩
