How do you initialize (through initializer lists) a multidimensional std::array in C++11?

c++, c++11

Solution

Try to add one more pair `{}` to ensure we're initializing the internal C array.

std::array<std::array<int, 2>, 2> shape = {{ {1, 1},
                                             {1, 1} }};

Or just drop all the brackets.

std::array<std::array<int, 2>, 2> shape = { 1, 1,
                                            1, 1 };

Problem

I am trying to initialize a 2D std::array trough initializer lists however the compiler tells me that there are too many initializers. e.g.: ``` std::array<std::array<int, 2>, 2> shape = { {1, 1}, {1, 1} }; ``` Compiler error: error: too many initializers for `‘std::array<std::array<int, 2ul>, 2ul>’` But clearly there aren't too many. Am I doing something wrong?
