The C language allows us to create custom data types.
The structure is a custom data type which c combines different data types .
The structure is a custom data type which combine different data types to form a new user define data type.
Definition
A structure is a collection of variable reference under one name providing a con vincible means of related information together.
Format: struct tag_name
{
data _type member1;
data_type member2;

};
here a keyboard struct declares a structes to hold the details of field of different data types.
Example:
struct addr
{
char name [30];
char city [15];
int pincode ;
};
Creating Structure variable
structure can be created in two ways:
1. declaration using tagname anywhere in the program.
Example:
struct book
{
char name [30];
char author [25];
float price;
};
struct book book1 book2
2. it is also allowed to combine structure declaration and variable declaration in one statement.
Example:
struct person
{
char *name;
int age;
char*address;
};
p1,p2,p3
while declaring structure variable along with their definition, the use of tag-name is optional.
Struct
{
char *name;
int age;
char * address;
}
p1,p2,p3
