[問題] std::array class 跟普通的array哪個好?
問題(Question):
在coursera看到有人用std::array去宣告array
http://www.cplusplus.com/reference/array/array/
可是array不是用一般方式宣告就好了嗎?
例如說 int foo [5] = { 16, 2, 77, 40, 12071 };
多include 一個array標頭再宣告成
std::array<int,5> foo = { 16, 2, 77, 40, 12071 };
不是比較麻煩嗎?
我想問的是用std:array宣告array有啥特別的優點呢?
謝謝。
