Can I initialize an array of array with all 0s?

Question

I have this:

uint8_t buf[X][Y];

I would like to initialize all elements to 0. Will this do the trick:

uint8_t buf[X][Y] = { 0 };

? i.e. will it initialize all X*Y elements to 0?

Answer 1

Yes. If you have an initializer ({ ... }), all elements not explicitly initialized will be initialized to zero.

Edit: Removed part that is not correct when using C.
