LNK1120: 1 unresolved externals and LNK2019: unresolved external symbol

Question

I\'ve been getting these two errors and I cant seem to find a solution that works.

LNK1120: 1 unresolved externals

Error 1 error LNK2019: unresolve

Answer 1

Did you implement the Vector3D default constructor, copy constructor, and destructor? You showed your headers but not the implementation files. The linker complains about a missing defintion of Vector3D::Vector3D(Vector3D const&).
