Please explain the error message and provide the solution. Thank You....................................................................................................................

You generally have two main steps to build a program : compilation of sources into objects, then linking of these objects into an executable. Your error message suggests that you did not provide all the objects to the linker, or in the wrong order. What is your command that generated this error ? — SR_, Sep 09 '21 at 07:28

How did you compile these two files? This error suggests that the "Account.cpp" is not compiled or linked by you. Try this:

gcc Account.cpp main.cpp
