Inheritance Problem

Dave2013 (5)
Hey all, I am new the C++ language and come from a Java background. I have three C++ files (main.cpp , Person.cpp and Employee.cpp). Header files also exist respectively with constructor and function prototypes for Person.cpp and Employee.cpp. Person has a constructor that initializes its variables and a function which outputs the variables to the screen, Employee Inherits from Person. My question is, is there a way for Employee to pass its constructor arguments into the Base class constructor to initialize them that way? Or am I talking non-sense. Any help would be appreciated :)

Yes.

I assume Employ's constructor should have the same parameters as Person. If that's the case, the constructor looks like:
1
2
3
4
 
Employee::Employee(string n, int a, string addr, float s) :
    Person(n, a, addr, s)
{
}
