Datatype is a spacial keyword used to allocate sufficient memory space for the data, or you can say data type is used for representing the data in main memory (RAM) of the computer.
Derived data types are those whose variables allow us to store multiple values of same type. But they never allows to store multiple values of different types. These are the data type whose variable can hold more than one value of similar type. In general derived data type can be achieve using array.So array is seconday data type.

Lets first understand the various classification of Data Types
1. Fundamental or Built-in data types (Primary Data Types).
2. Derived data types (Secondary Data Types).
3. User Defined data types.

The basic built-in or fundamental data types that are available in any programming language, in C we have int, float, double and char as builtin data types.
Derived data types are those data types which are derived from the fundamental data types using some declaration operators. In C we have Arrays, Functions and pointers, Structures and Classes as derived or secondary data types.

I hope this will clear your doubt.
