Initialize a static member ( an array) in C++

Question

I intended to create a class which only have static members and static functions. One of the member variable is an array. Would it be possible to initialize it without using constructors? I am having lots of linking errors right now...

Click to copy

class A { public:   static char a[128];   static void do_something(); }; 

How would you initialize a[128]? Why can't I initialize a[128] by directly specifying its value like in C?

Click to copy

a[128] = {1,2,3,...}; 

Answer 1

You can, just do this in your .cpp file:

Click to copy

char A::a[6] = {1,2,3,4,5,6};
