Those data types which are derived from the fundamental data types are called derived data types. Function, arrays, and pointers are derived data types in C programming language. For example, an array is derived data type because it contains the similar types of fundamental data types and acts as a new data type for C..
Keeping this in view, what is meant by derived data type in C++?
A derived data type is a collection of data types that describes the rules for interpreting the information stored in a contiguous region of memory. Some authors refer to them as user-defined types, some as programmer-defined types. Both the C and the C++ languages provide syntax for declaring derived data types.
Similarly, why is an array called a derived data type in C++? An array is a derived data type because it cannot be defined on its own, it is a collection of basic data types usually, such as integers, doubles, floats, booleans, etc. In object oriented languages you can have your own class which can be the basis of an array.
Besides, what is meant by derived data types?
Derived data type is the aggregation of fundamental data type. character, integer, float, and void are fundamental data types. Pointers, arrays, structures and unions are derived data types. Character is used for characters.
What is the difference between user defined data type and derived data type?
are int(integer) , char(character), float, double, bool etc. Derived Data Types are array, pointers etc. User Defined data types are those which are defined by the user using basic data types in them.

In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists of instruction s that tell the computer what to do and data that the program uses when it is running.What is Array explain with example?
Array. An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. For example, a search engine may use an array to store Web pages found in a search performed by the user.What is user defined data type?
A user-defined data type (UDT) is a data type that derived from an existing data type. You can use UDTs to extend the built-in types already available and create your own customized data types.What is enum in C?
Enumeration (or enum) in C. Enumeration (or enum) is a user defined data type in C. It is mainly used to assign names to integral constants, the names make a program easy to read and maintain. The keyword 'enum' is used to declare new enumeration types in C and C++. Following is an example of enum declaration.What is primary data types in C?

What is void data type?
void data type: it is actually refers to an object that does not have a value of any type. when we have defined functions that return no value, i.e. functions which only print a message and have no value to return. Such a function is used for its side effect and not for its value.What is a pointer in C?
Pointers in C language is a variable that stores/points the address of another variable. A Pointer in C is used to allocate memory dynamically i.e. at run time. The pointer variable might be belonging to any of the data type such as int, float, char, double, short etc.What is data structure in C?
Data Structures in C are used to store data in an organised and efficient manner. The C Programming language has many data structures like an array, stack, queue, linked list, tree, etc. A programmer selects an appropriate data structure and uses it according to their convenience.What is array in C?

Primitive data types are the general and fundamental data types that we have in Java and those are byte, short, int, long, float, double, char, boolean . Derived data types are those that are made by using any other data type for example, arrays. User defined data types are those that user / programmer himself defines.What is difference between data type and abstract data type?
The basic difference between abstract data type (ADT) and concrete data type is that the latter allow us to look at the concrete representation, whereas the former hide the representation from us. An ADT may be pure ADT or Updatable ADT. An updatable ADT is one where some operations actually change values of the ADT.What does primitive data type mean?
Primitive data types are predefined types of data, which are supported by the programming language. For example, integer, character, and string are all primitive data types. Programmers can use these data types when creating variables in their programs.
