There are three types of index data structures: unique, non-unique, bitmap
Database indexes do not contain data; they are structures that improve the speed of data retrieval.
Integer (signed or unsigned)
AnswerStructure Is an Collection Of Different Data Types.
Structures are a way to group different data types together under one name. They allow you to create more complex data structures by combining variables of different types, making it easier to manage and manipulate related data. Structures help in organizing data in a meaningful way for better understanding and usage in programming.

In c language data types are used to specify the tye of data.for ex:int a;It means "a" is a variable of type integer.There are two types of data types in c.They areprimary data typessecondary data typesprimary data types are the built in data types and secondary data types are the user defined data types.eg for primary data types are int,float,char,long,double..and for secondary are arrays,structures,pointers,unions..
A structure is not a data type. We use structures to define new data types (user-defined data types). If we didn't have the ability to create user-defined types we'd be limited solely to the built-in data types and arrays of those types.
Not necessarily. A table of structures can store a variety of data types provided the structures themselves are of the same type.
Index is a data structure that improve the performance of data.
Programmers have to declare various data types while coding in order to inform the computer how to handle them. The types include numbers, arrays, characters, booleans and structures.
You seem to have lost your text book so I am giving you a link where you can study data types, including derived data types.
Primitive data structures are basic data types that are built into programming languages, such as integers, floating-point numbers, characters, and booleans. They are simple and efficient, making them ideal for storing and manipulating individual pieces of data. These data structures are commonly used in algorithms and data processing tasks due to their speed and low memory usage.
