"namespace" and "class"

[janek]

I have a question:

what differences are between:


namespace Mary {

int r = 5 ;

char m[r] ;

void print1() ;

}


and


class Mary {
private :
int r = 5 ;
char m[r] ;

public :
Mary();
~Mary() ;
void print1() ;
}


excluding "private", "public", contructor and destructor in "class Mary" ?
Generally: what differences are between using declaration of "namespace"
and "class" ?

In the class case, members m and r are not visible outside the class.
However, in the namespace case, m and r *are* visible to anyone
accessing the namespace.

Also, the namespace variant will create global m and r, the class case
has them as instance data.

This program does not work as as c++ doesnot support variable sizeof
arrays like that.

This program does not work as it has a variable array inside the
namespace which is neither supported in c or c++
