Defining constexpr static data members

Question

So, I\'m aware that in C++ static members can be initialized inside the class if they are a const literal type like the following

class test{
public:
               


        

Answer 1

static constexpr int stc = 1; // declares the static var

constexpr int test::stc; // defines the static var
