I have an Account class in which Date object is a member of it.
When I created an account class:
These errors are coming up:
////////

Account_main.cpp is place where I create an Account object.
Also please help in understanding these errors!!

"Undefined reference" usually means the compiler can see that you use
a function, but it can't see the function itself (the definition, the
body, the implementation). 'Date::Date' is a constructor. Did you
show your compiler where the implemenation of 'Date' class is located?

Try it the other way round.

Did you *have* to quote the whole thing just to add one line?

Definitely! No, just kidding. I was in a rush and forget to cut out the
source code.
