Hello World.

I'm simply using
Code:
vector e1;
in a code an get this message when compiling:

Code:
sampleFaceSet.C: In function ‘int main(int, char**)’:
sampleFaceSet.C:107: warning: ‘e1.Foam::Vector<double>::<anonymous>.Foam::VectorSpace<Foam::Vector<double>, double, 3>::v_[0]’ may be used uninitialized in this function
sampleFaceSet.C:107: warning: ‘e1.Foam::Vector<double>::<anonymous>.Foam::VectorSpace<Foam::Vector<double>, double, 3>::v_[1]’ may be used uninitialized in this function
sampleFaceSet.C:107: warning: ‘e1.Foam::Vector<double>::<anonymous>.Foam::VectorSpace<Foam::Vector<double>, double, 3>::v_[2]’ may be used uninitialized in this function
What does that mean?
