How can I initialize normal array member variable in initializer list?

Question

I would like to do the following:

class MyClass {
    public:
        MyClass() : arr({1,2,3,4,5,6,7,8}) {}

    private:
        uint32_t arr[8];
};
         


        

Answer 1

Works perfectly on GCC 4.5.2 with -std=gnu++0x. I get a warning and a freeze with -std=c++98.

Answer 2

Your syntax is correct. Alternatively, you can say arr{1,2,3,...}.

Most likely is that your compiler just doesn't support this construction yet. GCC 4.4.3 and 4.6.1 both do (with -std=c++0x).
