Yes.

Sorry if this has been discussed earlier.  If so, please give me
a hint of where I can catch up.

I think I recall that I read somewhere that you should be able
to construct standard library vectors for objects without
default constructors.  It seems resonable since there is a
constructor in vector<> that takes an object with which to fill
the vector.

I'm currently using VC++ 5.0 and it refuses to compile since
there is no default constructor for my class.

explicit vector( size_type _N,
                 const _Ty& _V = _Ty(),  <<== here it barks
                 const _A& _Al = _A() )

I do think I recall that the article said that the compiler
shouldn't try to use the default argument value here since
I supply my own, as in:

vector<X> a( 100 );          // shouldn't work, no default ctor
vector<X> b( 100, X( 1 ) );  // should be ok, default
                             // ctor not needed

Am I right?
