Initializing Constant Static Array In Header File

Question

Hi,

I have just found out that the following is not valid.

//Header File
class test
{
    const static char array[] = { '1', '2', '3' };
};

Where is the best place to initialize this?

Thanks in advance;

Answer 1

//Header File 
class test 
{ 
    const static char array[];
}; 

// .cpp
const char test::array[] = { '1', '2', '3' }; 

Answer 2

The best place would be in a source file

// Header file
class test
{
    const static char array[];
};

// Source file
const char test::array[] = {'1','2','3'};

You can initialise integer types in the class definition like you tried to do; all other types have to be defined and initialised outside the class definition, and only once.
