Edit Question
Title
Body
A std::array<T> is essentially a C-style array wrapped in a struct . The initialization of struct s requires braces, and the initialization of arrays requires braces as well. So I need two pairs of braces: std::array<int, 5> a = {{1, 2, 3, 4, 5}}; But most of the example code I have seen only uses one pair of braces: std::array<int, 5> b = {1, 2, 3, 4, 5}; How come this is allowed, and does it have any benefits or drawbacks compared to the first approch?
