Re: [Dev-C++] Newbie class/vector/implementation problem

[Per W. <pw...@ia...>]

First of all, A variable type Employee should be a single employee and not
a container object. The nameing is confusing.

Secind - why a vector? Are empoloyees a numbered, continuous sequence? I
would more think of a map, which maps from an employee identifier
(employment sequence number or whatever) and the employee data.

Then you might write an DeleteEmployee() fnctions that takes the key
value of an employee and locates the employee in the map. You might also
remove an employee directly by iterating through the map and using the
iterator to specify which employee to delete.

If you can have only a single map of employees (you were planning on
declaring your vector in the implementation file) you don't need any
reference to the container in your deleteEmployee() and addEmployee()
calls. If addEmployee() and deleteEmployee() are ordinary functions they
might access the employees container as a static global variable inside
the implementation file.

However, you should think about your need to write specific functions for
add and remove of employees. If you want to perform special actions it
might be an idea to create an Employees class owning the container and
having add()/remove() as methods. If no extra work is needed, you don't
need addEmployee(), deleteEmployee() since you may operate directly on the
container.
