I'm not sure what point you're trying to make here.  You certainly don't 
have to write a constructor for a subclass in C++.  This works perfectly 
fine (and prints "Foo" when I run it):

#include <stdio.h>

class Foo {
public:
    Foo() {
        printf("Foo()\n");
    };
};

class Bar : Foo {
};

int main(char**, int) {
    Bar b;
}
