What is data structure why is an array called a data structure which are the other data structures?

A data structure is a collection of more than one elementary item, in some kind of aggregate organization.
An array is a type of structure where more than one item of the same type are arranged serially in memory, and accessed using an index. The item can either be an elementary type or it itself can be a structure type.
A struct (not to be confused with the use of "structure" in this answer) is a type of structure where more than one item of the same or different types are arranged serially in memory, and accessed using the structure member (.) operator.
A union is similar to a struct, except that each member occupies the same address. This means that only one type of data can be stored at any one time in a union.
A self-referential structure is a type of structure, usually constructed of simpler structures, linked together with some kind of pointer scheme. Examples of this are the linked list and tree.

What is a parallel array?
a parallel is data structure for representing array of records.
What are primary data structure?
A primary data structure is a data structure that is created without the use of other data structures, whereas a secondary data structure relies on a primary data structure. A data structure is an organized collection of data elements.[NOTE: Be careful not to confuse the term data structure with the term data type. It is a common mistake. This answer addresses dat structures. Often people who ask about primary data structures or primitive data structures are really asking about primitve data types.]Here is an example where an array is a primary data structure and a binary tree is a secondary data structure based on the array:An array is a primary data structure -- it is a set of sequentially numbered data elements, such as an array of integers or an array of names -- name0, name, name2, ...A binary tree is a data structure where each element (called a node) has a data component and pointers to it's left and right sub-trees. [Think of a directory of folders, but each folder can only have two sub-folders.] We can create an and store an array of nodes to set up the tree in languages like C++ or Java.The root of the tree could be node 1 in the array, it would point to nodes 2 and 3. node 2 would point to nodes 4 and 5, while node 3 would point to nodes 6 and 7 .. and so on. generally node n point to nodes 2n and 2n+1. (You can start with node 0, but the math is a little easier if you start with node 1.)The binary tree in this case is the secondary data structure, while the undelying array is the primary data structure.
What is a complex data structure?
A complex data structure is the kind of structure that has two arrays. One array hols the real part of the complex data and the other array holds the imaginary part.
Why is an array called a data structure?
An array could be called static because it is generally not changed structurally once it is created, meaning that you do not add, delete or swap the nodes themselves, though you will likely modify the data contained by the nodes. This differs from a more dynamic data structure, such as a linked list, where adding, deleting or swapping nodes is relatively simple.
Detailed difference between structure and array?
1). Structuer is a group of diffrent data type & set of diff. data type element can manupulet by using structuer .It Size is Addition of all Data type size e.g(int,float,char*2+4+1) =7 byte size of structure 2.) Array is Collection of Same data Type Element it is intege Array , Char Array , ponter Array,Objeact Array etc,
What is meant by array with in structure in c language?
It means a structure has a member that is an array: typedef struct foo { int x[42]; // an array of 42 integers // other members... };
Describe the advantages and disadvantages of array in data structure?
Array Pros:can access any element of an array directlycan be used to create other useful data structures (queues, stacks)light on memory usage compared to other structuresArray Cons:rigid structurecan be hard to add/remove elementscannot be dynamically resized in most languages

What are the differences between structures and arrays?
Arrays are collections of repeated data items. Structures are complex data items made up of other data items, including, potentially, other structures and arrays. You can, of course, also have arrays of structures. Array items can be accessed by using its subscript whereas structure items can be accessed using its dot or "arrow" operator in C, C++, C#, Java, and JavaScript.
What is difference between structure and array?
An array is a made up of elements of the same type e.g. strings or integers. A structure on the other hand can be made up of elements of different types.
Why is secondary called secondary?
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.

What type of cell structure do archaebacteria have?
Eubacteria and Archaebacteria lack a cell nucleus and other cell structures called organelles.
How do you implement a FIFO structure?
FIFO is a first-in, first out structure. In other words, it is a queue. The most efficient way to implement a queue is with a circular array.
