See https://gcc.gnu.org/onlinedocs/gcc-4.4.4/gcc/Designated-Inits.html

And here is one more tips.

Sometimes, you may want to initialize all array element with same value.

Then, you can do it as follows if you are using GCC.

static const int arr[10] = {[0 ... (sizeof(arr)/sizeof(arr[0]) - 1)] = 10};
