帶著對題主的膜拜心裡，想知道題主被什麼技術問題難住了，點進來卻發現這是個關於的英語的問題！以下是《牛津英語詞典》(OED)的附加解釋:
Different from, different than, and different to: are there any distinctions between these three collocations, and is one more correct than the others? Since the 18th century, different than has been singled out by critics as incorrect.
In practice, different from is the most common structure, both in the UK and North America, while different than is almost exclusively used in North America. It is difficult to sustain the view in modern standard English that one is more correct than the others, however. There is little difference in sense between the three, and all of them are used by respected writers.

關於c 函式匹配的乙個問題？
冒泡 精確匹配是說你這裡如果有個引數為char的過載，那就匹配這個，如果沒有，那剩下的int和short選int，因為比int短的整型的隱式提公升都是一步到int，而不是選最近的 白如冰 The following implicit conversions are classified as int...
