Why can't fixed arrays be in class?

[Immortal Nephi]

I tried to put fixed array into class, but the C++ Compiler generates
an error as syntax error of '{'. I don't find anything wrong. Fixed
array is used to have a list of strings.

For example

class Test
{
public:
Test();
~Test();

private:
static const char List_Strings[5][10] =
{
"abc",
"def"
};
}

Only static constant integers can be initialized in the class; the rest
can be initialized only in the (separate) definition:

// Test.hpp
class Test
{
// Declaration only
static const char List_Strings[5][10];
}

// Test.cpp
// Definition and initialization
const char Test::List_Strings[5][10] =
{
"abc",
"def"
};
