![Array of Structure
We can also declare an array of structure.
Each element of the array represents a
structure variable.
Example : struct employee emp[5];](https://image.slidesharecdn.com/structuresv122102017-1-180831193305/85/Structures-in-c-language-12-320.jpg)
Structures in c language
- 2. Definition Structure is a user-defined data type in C which allows you to combine different data types to store a particular type of record. It is somewhat similar to an Array. The only difference is that array is used to store collection of similar data types while structure can store collection of any type of data.
- 3. Example: Structure is used to represent a record. Suppose you want to store record of Student which consists of student name, address, roll number and age. You can define a structure to hold this information. Suppose you want to keep track of your books in a library. You might want to track the following attributes about each book − Title Author Subject Book ID
- 4. Defining a structure struct keyword is used to define a structure. struct defines a new data type which is a collection of different types of data. Syntax : Note: The closing braces in the structure type declaration must be followed by a semicolon(;).
- 5. Example of Structure •Here the struct Book declares a structure to hold the details of book which consists of three data fields, namely name, price and pages. •These fields are called structure elements or members. •Each member can have different data type,like in this case, name is of char type and price is of int type etc. •Book is the name of the structure and is called structure
- 6. Declaring Structure Variables It is possible to declare variables of a structure, after the structure is defined. Structure variable declaration is similar to the declaration of variables of any other data types. Structure variables can be declared in following two ways.
- 7. 1) Declaring Structure variables separately
- 8. 2) Declaring Structure Variables with Structure definition
- 9. Accessing Structure Members Structure members can be accessed and assigned values in number of ways. Structure member has no meaning independently. In order to assign a value to a structure member, the member name must be linked with the structure variable using dot . operator also called period or member access operator.
- 10. We can also use scanf() to give values to structure members through terminal.
- 11. Structure Initialization Like any other data type, structure variable can also be initialized at compile time. Or
- 12. Array of Structure We can also declare an array of structure. Each element of the array represents a structure variable. Example : struct employee emp[5];
- 13. The below code define an array emp of size 5 elements. Each element of array emp is of type employee
- 14. Nested Structures Nesting of structures, is also permitted in C language. Example :
- 15. Structure as function arguments We can pass a structure as a function argument in similar way as we pass any other variable or array. Example:
