You need to call a constructor in Person when constructing an Employee. By default, the compiler will call the default constructor (with no arguments), but in this case, it doesn’t exist in Person (the compiler creates a default constructor only if no other constructor exists).
You must call to a concrete constructor of Person in the first line of Employee constructor, or defining a default constructor in Person.
