Re: initialization of static reference.

 In the following snipet of code is it guaranteed that foo::coords_
will be initialized before foo::active_coord_ ?

 I mean is it guaranteed that the reference &active_coord_ will be
valid ?

 Thanks a lot for your response.

 #include <vector>
 #include <iostream>

 class foo {
    public:
     static std::vector<size_t> coords_;
     static size_t &active_coord_;
 };

 std::vector<size_t> foo::coords_( 1 );

 size_t &foo::active_coord_ = coords_[ 0 ]; // Is it safe ?

 int main() {
    foo ob;

    foo::coords_[ 0 ] = 10;
    std::cout<<" active coord is "<<ob.active_coord_<<"\n";

    return 0;
