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?

Have you tried it? Did it work? Did it work with `{ 1 }`? – pts Aug 01 '14 at 08:03

To initialize zeros `= {};` is enough. – ST3 Aug 01 '14 at 08:05

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.

2That's valid C++, but C syntactically requires something between the braces. (C11 §6.7.9/1) – Potatoswatter Aug 01 '14 at 08:05

1@Potatoswatter That is correct. Doesn't work with empty brackets. – Bogdan Alexandru Aug 01 '14 at 08:06
