Memberwise copy

It really doesn't help when we don't know what the error is.

It would also help if you rewrote the program using std::array/std::vector and std::string.
In the current form it's neither C nor proper C++.

It really doesn't help when we don't know what the error is.

I get 2 undefined references:to "Website" constructor and to "User" constructor.

I have a muti-source program:classes.h, implementation.cpp, and main.cpp.I defined all my classes in classes.h and #included classes.h
and implemented my classes in implementation.cpp .main.cpp contains my driver program

it would also help if you rewrote the program using std::array/std::vector and std::string.

I don't think STL classes have serialize methods

Hello?!

The error basically means you are trying to call the constructor of the Website class and the User class and they have no implementation that is linked.

but I think I have both implemented and defined them
