_ underscore
- hyphen, dash　兩個都得
# pound / pound sign, sharp, number sign, octohorp, hash 全部都得
. fullstop＜英＞, period＜美＞
, comma

1. _ underscore
2. - hyphen and dash are both correct
3. # pound sign or number sign

Answer 4

_ 是underscore，中文是底線。
- 是hyphen，dash是長的，大約-------那麼長，當然是連埋的，不過打不到出來（可以說是中文的破折號吧＜＜不太肯定的），字典的解釋就是「長劃」。　　
#是sharp (音樂上)
