An array stores a list of values, usually of the same type. Values are distinguished by a subscript.
A class usually doesn't store objects, but it defines a template for objects. Objects based on this class store data, which can be of different types, and are distinguished by name (similar to variables). A class thus defines a new, composite, data type (so does an array, but in a more limited way).
Besides, a class can also define functions (usually called "methods"), specifically for objects of that type.
Usage example: If you want to sort 100 numbers, or do some other work with them, you might store them in an array of numbers (integers, or floating-point numbers, depending on your needs).
If, on the other hand, you want to store information about a person, you might create a class, where you define that a "person" includes information about a first name, last name, birthdate, etc.

∙ 14y agoAn array is a collection of the same type of data, for example, integers. Each element is accessed through an index - a numerical value. For example, myArray[x], where "x" is an integer variable.
An object (created from a class) can store different types of data; each is accessed through its name, for example, person.age, person.name, etc.
An object, or class, also has several other properties that distinguish it from an array; for example, classes/objects also have methods (functions defined at the class level), and with classes you can have inheritance.

Why is an array called a derived data type?
An array is not a derived data type at all. In order to be derived there has to be a base class and an array has no base class. Here is the basic declaration of the std::array template class from the <array> header file: template<class _Ty, size_t _Size> class array { // fixed size array of values // ... }; A vector, on the other hand, is derived (from the <vector> header file): template<class _Ty, class _Alloc = allocator<_Ty>> class vector : public _Vector_alloc<!is_empty<_Alloc>::value, _Vec_base_types<_Ty, _Alloc>> { // varying size array of values // ... };
