Structure in c

Answer 1

Structures are a way of storing many different values in variables of potentially different types under the same name. This makes it a more modular program, which is easier to modify because its design makes things more compact. Structs are generally useful whenever a lot of data needs to be grouped together--for instance, they can be used to hold records from a database or to store information about contacts in an address book. In the contacts example, a struct could be used that would hold all of the information about a single contact--name, address, phone number, and so forth.
->A structure is a collection of related elements , possibly of different types , having a single name.

->"each element in a structure is called field".

->A FIELD is a smallest element of named data that has meaning. It has many characteristics of the variable .

->It exits in memory . it can be assigned values, which in turn can be accessed for selection or manipulation.

-> A field differs form variable primarily in that it is a part of structure.

ITS SYNTAX IS:

struct tag name

{

field list;

};

Answer 2

a structure is like an array in that array(derived data type) is a collection of variables of similar datatypes whereas a structure(user defined data type) is a collection of variables of different data types

Answer 3

A structure (from now on called struct), is a list of several ODT (old data types).

I can have a structure that keeps track of, let's say my user info:

struct User {

char Username[256];

int TimeOn;

};

Note the semicolon.

Now, you can access structs by declaring a variable of struct User.

struct User UserOne;

UserOne.Username = "Bob";

UserOne.TimeOne = 0;

Answer 4

in arrays we can create number of variables in same data types but in structure we can create our own data types..

EXAMPLE:

typedef struct

{

int id;

char name[36];

int sal;

}emp;

in that above example we create emp data type it use 40 bytes of memory space.

Answer 5

Structures in C are user defined data types. They can hold a number of values but all must be of the same type.

Answer 6

data structure in c means data structure through c language but data structure means data structure through all programming languages like c, c++ and jawa etc.

Answer 7

i don't know what is data structure but say that data structure is vary importent in our life
