does "struct_name var = { 0 }; " fill var with 0?

[Fred]

I have seen this syntax and would like to know weither var_name is entirely
filled with zeroes or only a first few bytes are zeroed (for example the
first field of the structure).

I have of course tried it with MSVC and it seemed to fill the entire
structure, but is this the norm? Where can I find more informations?

thanks in advance,
Fred

Yes.

The C++ standard.

occasionnaly reading the norm?
