static const array of const structure

[Dario de Judicibus]

I wish to define in my application a static constant array of static
constand structure. I am not sure which is the right declatarion and
initialization.

For example, if structure is

MYSTRUCT.H
struct MyStruct
{
String name ;
int value ;
}
static const MyStruct * const arrayOfMyStruct ;

is that correct?

const MyStruct arrayOfMyStruct[] =
{
{"George",127},
{"Mary",212}
} ;

That's not an array, but a pointer. And since that pointer is const,
you'd have to initialize it immediately. It can't be changed later. But
it doesn't match the below definition, which is not a pointer, but an
array.
If you want to declare your array in the header, you need to add the
size and make it extern. The rest has to look the same as in the
definition:

extern const MyStruct arrayOfMyStruct[2];

is that correct?

const MyStruct arrayOfMyStruct[] =
{
{"George",127},
{"Mary",212}
} ;
