in c++ language ...function is a derived data type ?
Data types are dependent on the language. Please note the language you talk about. You might be talking about treating functions as objects, what many modern languages do. And objects can be considered derived types, because you build them from numbers and strings etc. When you treat a function as an object you can manipulate it with other functions. Much like the derivative in maths: The derivative takes a function and gives back another function.
