behavior compiler

基本解釋

If you want the compiler's previous behavior, remove the array from the constructor's member initialization list.
如果您要編譯器的舊行為，請(qǐng)將該陣列從建構(gòu)函式的成員初始設(shè)定清單中移除。
Leaving it to the compiler to implement the default behavior is simpler, less error-prone, and often leads to better object code.
留給編譯器來實(shí)現(xiàn)缺省行為更簡(jiǎn)單些，更不易出錯(cuò)，并且常常會(huì)產(chǎn)生更好的目標(biāo)碼。
The reason for this behavior is that, at compile time, the compiler only knows that T is a reference type, and therefore must use the default operators that are valid for all reference types.
這種情況的原因在于，編譯器在編譯時(shí)僅知道 T 是引用類型，因此必須使用對(duì)所有引用類型都有效的默認(rèn)運(yùn)算符。
