[Dev-C++] Derived class initialization

[softnasolutions-ltd.fsbusiness.co.uk <so...@so...>]

Hi all,
I'm stuying C++ using some sample programs and I have come accross this =
line of code which i don't quite understand. PLease sombody tell me what =
it means.

derivedclass::derivedclass(classgrade *ave, name, age) : baseclass(ave, =
name, age).

What i don't understand is what it means to have :baseclass(ave, name, =
age). I figure it has something to do with initiallising the derived =
calss. but i don't understant exactly what it does.

Thnx.

Napoleon.
