HOW DO WE DECLARE AND INITIALIZE CONSTANT CHAR ARRAY? [1]
-----------------------------------------------------------
class Test
{
public:
static const int arr[]= {1,2,3}; // LINE 11
}

You can declare it here, but you can't initialize it here.
Initialize it in a separate definition.

Otherwise, you will get compiling error
"a brace-enclosed initializer is not allowed here before '{' token"

Header file:
class Test
{
public:
static const int arr[];
};

Implementation file in *.cpp:
const int Test::arr[3] = {1,2,3};


iostream linker error is solved by using g++ instead of gcc in makefile.
-----------------------------------------------------------------

Mistake to avoid when using 'inline'
-------------------------------------------------------------
1.Don't put inline in front of class constructor/destructor
2.Don't put inline in front of functions within 'namespace'.
